THE INDIAN MUSEUM: 1814—1914. 
He contributed a few papers to the Royal, Zoological, and 
Entomological Societies, and a great many to the Annals and 
Magazine of Natural History, which embodied his original 
work not only in the field of systematic and descriptive zoo- 
logy, but upon morphology—especially the morphology of 
Arthropoda; upon phylogeny—especially the phylogeny of 
Insecta ; upon physiology, and upon the philosophy of zoo¬ 
logy. It was in the last branch of the science that his inquir¬ 
ing, original genius found its happiest exercise, and he was 
particularly interested in all problems as to the significance of 
animal organs. More than most systematic zoologists was he 
dissatisfied with the dry facts of animal structure, and his 
desire to see through these facts into their origin and meaning 
—to make zoology really a science of living beings—may be 
said to have been a passion with him. Unfortunately his 
published work in this direction does not represent a fraction 
of his accumulated knowledge, principally because he had an 
almost fastidious objection to publishing anything that was 
not exhaustively complete. But this philosophical bent of 
his mind is amply illustrated by his papers on the claspers, 
and on the antennae, and on the femoral brushes of the Man- 
tidae ; on the mode in which the young of Astacidae attached 
themselves to the mother ; on the stridulating organs of Crus¬ 
tacea, of Arachnida, and of Myriapoda : on sexual charac¬ 
ters in Mollusca; on Mimicry; on the scent-glands of 
scorpion-spiders; on the meaning of Viviparity; etc. In 
purely systematic zoology his principal published works 
were :—(1) a catalogue of the Mantodea which was not com¬ 
pleted at the time of his death, and (2) a series of papers on 
the Butterflies of the Andamans and Nicobars and of Cachar, 
written in collaboration with Mr. deNiceville. These papers 
were the result of work undertaken between the years 18 SO¬ 
BS, when Mr. deNiceville was employed on the staff of the 
Museum, during which period he worked with that gentle¬ 
man almost exclusively at the Lepidoptera of the Indian 
region, the result being to greatly increase the collections in 
the Indian Museum and to add largely to faunistic knowledge. 
In this series of papers must specially be mentioned a very 
curious case of mimicry between two distinct groups of Papi-
