put into the hands of Mr. Leadbeater for preservation. If, there- 

 fore, the Society are anxious to compare the skins I send with the 

 heads of older and finer animals, they will find no difficulty in so 

 doing by applying to Mr. Leadbeater. 



" I send also in the same box the skin of a Mole (perhaps Talpa 

 leucura, Blyth) from Pekin. 



" A Hedgehog, which I take to be new, is also from Pekin. But 

 this species is also found in Shanghai, and has lately been captured 

 at Swatow. 



" In a bottle, preserved in spirits, you will find a small Mouse and 

 a Bat, besides several Snakes, Lizards, and Frogs. 



•' All these specimens have been fastened in a tinned box, and 

 shipped on board the 'Harkaway' bound for London. I enclose 

 you the mate's receipt." 



Extracts were also read from a letter addressed to Mr. T. Rupert 

 Jones by Mr. S. R. Pittard, containing remarks relative to the flight 

 of Albatroses {Diomedea) and other oceanic birds, as observed during 

 his voyage to Australia. 



The following papers were read : — 



1. List of Mammalia, Tortoises and Crocodiles collected 

 BY M. MouHOT IN Camboja. By John Edward G ray, 

 F.R.S., V.P.Z.S., F.L.S. 



(Plate XXI.) 



M. Mouhot having sent to Mr. S. Stevens a number of Mammalia 

 and other animals from Camboja, a series of them has been secured 

 for the British Museum Collection. 



I hasten to lay before the Society a list of all the specimens, and 

 the varieties that they present, with a description of the species or 

 varieties which appear to be new to science. 



Mammalia. 



There are eight specimens of the Long-armed Ape {Hylobates). 

 They differ considerably in colour, and yet offer some peculiarities 

 which I have not observed in specimens from other parts of India or 

 the Asiatic islands, so that I am induced to believe them to be a sepa- 

 rate species or local variety. M. Mouhot is inclined to regard them 

 as varieties or states of the same species ; as he observed that they 

 were all found in company on a small island near Camboja. 



1 . The oldest specimens, whether they are black with a more or less 

 grey back and white hands, or a white with a more or less long black 

 spot on the chest, generally have a large black spot on the crown of 

 the head, circumscribed by a pale edge ; some of the white examples 

 have white and others black whiskers. 



2. The two younger specimens are yellowish white, without any 

 black, not even the spot on the head ; but this may be only on ac- 

 count of their youth.
