THE INDIAN MUSEUM: 1814—1914. 
officers both military and medical, and notwithstanding 
the fact that the expedition took place at a time of year 
(the winter months) most unfavourable to many forms of 
life, his collections, which are being described by many 
specialists of different nationalities in a special volume (VIII) 
of the Records of the Indian Museum, were of exceptional 
interest, more especially as regards the lower vertebrates, 
the earthworms, mollusca, land planarians, and other 
terricolous and aquatic groups. The great '^find” of the 
expedition was undoubtedly a new genus and species of 
that peculiar group the Onychophora, intermediate in many 
respects between the arthropods and the annelid worms. 
This little animal has been named by Mr. Kemp Typhloperi- 
patus williamsoni, in memory of Mr. N. Williamson whose 
murder was the ultimate cause of the expedition. It is the 
only member of its group that has been found north of the 
Isthmus of Kra in the Malay Peninsula, and may, therefore, 
be said to be the only peripatus as yet known from continen¬ 
tal Asia. 
Two expeditions still remain to be considered. Both of 
them passed through Burma to Western China and in both Dr. 
J. Anderson, the first Superintendent of the Indian Museum, 
took a prominent part as medical man and naturalist. 
The first was in 1868 and the second in 1875. The zoologi¬ 
cal collections formed a basis of extensive research, both 
anatomical and systematic, on the part both of Anderson 
himself and of other workers in Calcutta. The results were 
published in two large volumes (text and plates) under the 
title of Anatomical and Zoological Researches : comprising 
an account of the zoological results of the two expeditions 
to Western Yunnan in 1868 and 1875; and a monograph of 
the two Cetacean genera, Platanista and Orcella.” Unfor¬ 
tunately a considerable proportion of the specimens appear 
either to have been lost after their arrival in Calcutta, 
or possibly never to have been brought back to India; 
for apparently Dr. Anderson was in the habit of pre¬ 
paring in the field very elaborate descriptions of the 
animals he collected, and of drawing detailed figures while 
they were still fresh. Those specimens that remain, how-
