Plateau Pika, O. curzoniae. Who was Mrs Curzon? I think I have found out

In 1858 Brian Houghton Hodgson (FRS 1877) gave the pika he first described and I wrote about in my last post, and now known to be a keystone species of the Tibetan Plateau, the specific name curzoniae. He ended his description:
This beautiful little animal is appropriately dedicated to the Hon’ble Mrs Curzon.
In the Eponym Dictionary of Mammals, the authors state: ‘Unfortunately this is as full a description of the lady as we can find’.

But who was she? The requirements for our Mrs Curzon are that as the Honourable Mrs Curzon she must have been the daughter of a viscount or baron, or to have married the son of one, and, it could be argued, have had a strong connexion with India.

I have been digging in genealogy websites and find that, out of several possibilities, Augusta Latham Hallifax (1837-1917) fits the bill. She was the daughter of Brigadier-General Robert Dampier Hallifax (sometimes shown as Halifax) and was born in South Africa. She married the Honourable Ernest George Curzon (1828-1885) on 14 January 1856 at Umbala (now Ambala), 120 miles north of Delhi.

Ernest George Curzon eventually became Colonel of the 52nd Regiment of Foot which served in India from 1853 until 1865. The regiment (later to become part of the Oxfordshire Light Infantry) took part in the Siege of Delhi during the Indian Mutiny in 1857, marching from Ambala. Augusta’s father would also have been in the Siege of Delhi had he lived long enough. Colonel of the 75th Regiment of Foot (later merged as part of the Gordon Highlanders), he was given the job as a Brigadier of leading one of two brigades from the vast military cantonment of Ambala to besiege Delhi. However, having passed Karnal, he became so ill that he was sent back there where he died on 1 June 1857. The Commander-in-Chief of the Army in India, George Anson, a Whig politician as well as a soldier, had died of cholera, four days after leaving Ambala, so it is possible or even highly likely that Hallifax was also a cholera victim.

Ernest George Curzon was the seventh child (out of ten) of Richard William Penn Curzon-Howe, 1st Earl Howe. Therefore he had the courtesy title of ‘The Honourable’, as did his wife. Four of Ernest and Augusta’s six children were born in India.

Hodgson’s paper* describing what we now know as the Plateau Pika appeared in the Journal of the Asiatic Society of Bengal. Volume 26 was published in 1858 but the papers were received in 1857. Indeed, his paper noted that it was sent from Darjiling (Darjeeling) in April 1857, fifteen months after Augusta Hallifax became ‘the Hon’ble Mrs Curzon'.

Fortunately, the National Portrait Gallery has two photographs (albumen prints) of Augusta taken in London by the French photographer, Camille Silvy (1834-1877) in 1860 (her fourth son was born in London in 1861):

Or does somebody have a better candidate for the beautiful little Mrs Curzon?

And here is Tim Melling's photograph of a Plateau Pika taken at about the same time as my video:

And, finally, Hodgson's paper to the Asiatic Society of Bengal:



*As well as the Plateau Pika, which he named Lagomys Curzoniae, he also described as a new species Mustela Témon which is now regarded as a subspecies of the Mountain or Altai Weasel, Mustela altai temon.

A morning on the Tibetan Plateau in Sichuan: 2. Plateau Pika - another fluffy animal

The Plateau or Black-lipped Pika, Ochotona curzoniae is an animal of, and confined to, the Tibetan Plateau. Ecologists have it marked as a keystone species of the Plateau where it is thought to increase plant growth by aerating and turning the soil through its burrowing. Many predators—like the Pallas’s Cat—rely on this species. Each family has a burrow with multiple entrances and a central nesting chamber.

As we found last November on the Plateau in Sichuan, they are extremely common. We were surrounded by pikas, eating close to a burrow or dashing from one to another. Also extremely common was the White-rumped Snowfinch (Onychostruthus or Montifringilla taczanowskii). We noticed that in areas where these snowfinches settled, the pikas appeared from their burrows. Presence of the finches appeared to assure the pikas that there were no predators near. Snowfinches nest in old pika burrows.

There was another species of snowfinch present in smaller numbers but formed into larger flocks, the Rufous-necked Snowfinch (Pyrgilauda or Montifingilla ruficollis).

Pikas do not hibernate (unlike marmots which had disappeared for the winter). The do make stacks of hay, usually inside the burrow, which they obviously use to supplement their diet of live grasses and herbs, especially in winter. They also have a much thicker, lighter-coloured coat in winter. However, it appears that mortality during the winter is high, with only 1-2% of adults surviving to breed for two years.

Pikas, like all lagomorphs, are coprophagic. They break down their vegetarian diet in the hindgut i.e. beyond the point that some of the nutrients produced can be absorbed. Two types of faecal pellet appear, the normal hard ones that litter the ground and special soft ones which they eat and send through the digestive tract again.

A Plateau Pika eats a lot of grass—61 g/day and there are lots of Plateau Pikas. It has been estimated that in energy intake terms, about 6.2 million kilojoules per hectare are consumed each year by pikas in the alpine meadows of Qinghai-Tibet or 1.3 times that consumed by the domestic sheep kept there*. It is perhaps then not surprising that the Plateau Pika is regarded as an agricultural pest and that they have been, and are being, poisoned in vast numbers in order to protect the existing, and encourage the spread of, livestock industry in China. The damage caused to the grassland, to predator populations and, ultimately, to agricultural productivity itself can be imagined. We see vast areas of natural grassland infested by domestic yaks: the locals see agricultural land infested by pikas and rodents. But we can hardly complain; we have fields upon fields of rye-grass monoculture for our livestock.

My video below shows a Plateau Pika that was filmed from the same position I used for the Pallas’s Cat (see my last post) at an altitude of over 3,500 metres.
