known, and the species are not to be mistaken." There is accordingly no means of de- 

 termining, with certainty, whether the animal here described is identical in species with 

 that of M. Desmarest, but the probability is certainly in favour of the identification. 



At present, we are really quite ignorant of what species of Monkeys inhabit the 

 countries bordering on the Bay of Bengal to the eastward. The Semnopitkecus ob- 

 scurus (Reid, P. Z. S. 1837, p. 14,) has recently been discovered by Mr. Cuming to 

 be very common at Singapore, " varying greatly in the depth of its colouring, no two 

 specimens being precisely the same. The general hue ranges from greyish-black, 

 or smoke-grey, to black; the [lengthened] occipital crest and the tail being always 

 paler than the rest." And as the Hylobates Lar, previously known only as an in- 

 habitant of the Malay peninsula, has been received by this Society from Moulmain, 

 where it is most probably the common species of the interior adverted to by Heifer, 

 it is likely that Semnopitkecus obscurus extends its range similarly northward, and 

 that it is the maurus of Dr. Heifer's list, mentioned as " a very wild inhabitant of the 

 loftiest trees, and considered the best food by the Kareans, who shoot it with poisoned 

 arrows." The true maurus appears to be confined to Java, being replaced in Suma- 

 tra by femoralis — the doubtfully cited maurus of Sir Stamford Raffles. 



P. 840. Returning now to my first Report, in the page cited I have mentioned spe- 

 cimens of Pteropus Edwardsii vel medius from the vicinity of Madras and from 

 Travancore, the latter with a note of doubt which may now be cancelled, as I have 

 obtained the same variety of colour here, as well as intermediate specimens; and 

 Mr. Hodgson has also forwarded specimens of his Pteropus leucocephalus and Pt. 

 pyrivorus from Nepal (vide J. A. S. IV. 700), the former being (as already asserted 

 by Mr. Ogilby) perfectly identical with Edwardsii, and the latter is Pachysoma 

 marginatum, also common here. A third species of Indian frugivorous Bat, the 

 Pt. Dussumieri, Is. Geoff. (Zoologie du Voyage de M. Belanger, p. S9J, is still 

 wanting to our collection. Length about eight inches, and extent nearly two feet and 

 a half. Face and throat brown ; the back and belly covered with brown hairs having 

 some whitish ones intermixed ; the upper part of the breast russet-brown ; and sides of 

 the neck, from the ears to the insertion of the wings, fulvous with a shade of russet. 

 Specimens of this Bat were obtained " on the Continent of India" by M. Dussumier, 

 and recently by Dr. Royle near Saharunpore. The Pt. Javanicus occurs in the 

 Tenasserim provinces, and a new species has been described by Dr. McClelland from 

 Assam, as Pt. Assamensis, P. Z. S. 1839, p. 148. 



Taphozous. For descriptions of four Indian species of this genus of Bats, vide

P. 841. Hamatornis pusillus, Nobis, or Ixos pusillus. This distinct species appears 

 to fill the place, in the peninsula of India, of /. Cqfer of Bengal and Nepal, which lat- 

 ter was unknown to Mr. Jerdon who so designated the other. It also inhabits Arracan. 



P. 922. The two races of Buceros ruficollis noticed, as inhabiting the Tenasserim 

 provinces, have proved to be distinct species; of which the true B. ruficollis, Vieillot, 

 is distinguished by its superior size, the flatness of its casque, and the lateral trans- 

 verse ridges on the basal portion of the bill itself; these last being constantly wanting 

 in the other, which has likewise the casque much more elevate or convex. In my Re- 

 port to Government on a collection of Tenasserim specimens forwarded by the late Dr.
