The British Museum Catalogue of Ungulate Mammals. 
By the death of the late Richard Lydekker systematic zoology 
suffered a great blow, for his knowledge in this province was 
profound, based as it was on a wide and deep paleontological 
foundation. More especially, he excelled in his knowledge of the 
reptiles and the mammals. The British Museum was therefore 
fortunate in being able to secure his services when it was decided 
to issue a Catalogue of the Ungulate Mammals in the Museum. 
Unhappily, however, death claimed him before he had completed 
his task, for the fifth and last volume yet remains to be written. 
The fourth, now under review, was completed only a few days 
before his death. This includes the deer, chevrotains, camels and 
lilamas, pigs and peccaries, and the hippopotamuses, and represents 
an immense amount of hard work and no little restraint; for he 
conceded much to present-day demands, both in the matter of 
nomenclature and of species ‘splitting ”—though under protest, 
which he records in his preface. We can sympathize with him 
when we come to realize that by the present standards of specific 
distinctions no less than six and twenty subspecies of the Virginian 
deer (Odocoileus virginianus) are now recognized, and of the 
chevrotain (Z’ragulus javanicus) there are twenty-three variants. 
A considerable number of these are unrepresented in the Museum 
collection, but he did well, nevertheless, to include them in this 
Catalogue. 
In the matter of illustrations it must be admitted much is left to 
be desired. ‘Their selection apparently depended not so much on 
the requirements of the work as upon the sources from which they 
could be obtained ready made. Hence it is that some, as in the 
case of the Persian fallow deer, fail to bring out the really distinctive 
characters of the species; while in the case of many other species 
no figures at all are given, evidently because there were no published 
figures available. These should have been specially prepared for a 
work of such importance. For this, however, he can hardly be 
held responsible. In spite of these small blemishes, this volume is 
in every way worthy of its predecessors, and will prove of immense 
value to students as well as to the Museum. 
Records of the Indian Museum.—Vol. VIII. Zoological Resulis of 
the Abor Ewpedition. Part 1X., 1916. 
Tur military results of the punitive force which entered the Abor 
country in 1911-12 have long since been digested and filed. The 
scientific results of that expedition, naturally, could not be so 
speedily estimated. In the ‘ Records of the Indian Museum’ above 
referred to Col. Godwin-Austen gives the results of his study of the 
slug-like Mollusca collected by Mr. Stanley Kemp, who was attached 
to that expedition as naturalist.
