36S Notes on the Fauna of the Nicobar Islands. [No. 173. 



Cynopterus marginatus, (B. Ham.) Inhabits India generally, as also 

 the countries eastward of the Bay of Bengal to Malacca, and the great 

 eastern archipelago. 



Hipposideros murinus, (Elliot) : vide /. A. 8. XIII, 489. Identical 

 with specimens from Southern India, and from the Malayan peninsula. 



In addition to the above, Capt. Lewis informed me of a large Monkey, 

 evidently a Presbytis (vel Semnopithecus) from his description, of which 

 he vainly attempted to obtain specimens, from its remarkable wildness ; 

 also of a large Squirrel, distinct from any in the Society's Museum, and 

 therefore probably new, considering the locality. 



Capt. Lewis likewise obtained, in the immediate vicinity of the Nico- 

 bars, an example of Delphinorhynchus rostratus, F. Cuv., as identified 

 from its skull which he has presented to the Society, and which entirely 

 accords with that of a specimen captured in the Red Sea. 



Sus The Nicobarian Pigs appear to have been derived from the 



Chinese domestic species, turned loose upon some of the islands.* 



It can scarcely be doubted, however, that several additional species 

 of mammalia remain to be discovered, as particularly Bats, with proba- 

 bly more Squirrels, and at least two or three species of small Carnivora, 

 and perhaps Insectivora. 



Aves. 



Palceornis caniceps, nobis, ante pp. 23, 51. Capt. Lewis obtained a 

 living specimen of this bird, with the wings and tail mutilated by its 

 native captor. Dr. Cantor has another and very fine specimen, evidently 

 a female, with black beak, from the Malayan peninsula. 



P. erythrogenys, nobis, ante p. 23. Specimens of this bird were pro- 

 cured both by Mr. Barbe and by Capt. Lewis ; and a living male was 

 given by the latter gentleman to Mr. Halfhyde, of the Preventive ser- 

 vice, who, when it died, presented it to the Society. This individual was 

 in far more beautiful plumage than the specimens previously examined : 

 it measured eighteen inches and a half in length, of which the middle 

 tail-feathers were ten and a half; expanse of wings twenty-two inches 

 and a half ; and closed wing seven inches and five-eighths : irides dull 

 greyish. The cheeks and ear-coverts, continued forward to the beak, 



* It may be here remarked, that Capt. Lewis has himself turned a pair of Cervus 

 axis loose, in a locality where they are likely to propagate.
