 Robert Hudson, Esq., F.R.S., V.P. in the Chair. 



The Secretary read the following report on the additions to the 

 Society's Menagerie during the month of April 1872. 



The total number of registered additions to the Society's Mena- 

 gerie during the month of April was 131, of which 10 were by birth, 

 32 by presentation, 77 by purchase, 2 by exchange, and 10 were 

 received on deposit. 



The most remarkable of the acquisitions were : — 



1. A Red-bellied Flying Squirrel (Pteromys magnificus, Hodgson : 

 Jerdon, Mamm. of India, p. 177), purchased April 10th, of a soldier, 

 who informed us that he obtained it at Donglee (qu. Tonglee) gulley 

 in the Himalayas. Mr. Berjeau's sketch (Plate L.) will give an 

 idea of the form of this fine species of Pteromys, which is quite new 

 to the collection. 



2. A young female Baird's Tapir (Tapirus bairdi), purchased 

 A.pril loth, having been brought by one of the Society's correspon- 

 dents from Corinto, on the western coast of Nicaragua. 



This animal, although not by any means full-grown, has nearly 

 lost the spots of immaturity which distinguished our former specimen 

 of this interesting species, received in August last * ; and as it also 

 differs from the adult as figured by Dr. Gray (P. Z. S. 1867, pi. xliii.), 

 I have thought it advisable to have a careful figure made of it 

 (Plate LI.). 



It stands about 23 inches in height, and is 42 inches long, from 

 the extended snout to the rump. Above it is rather thickly covered 

 with brownish-black hairs of about f inch in length. The face is 

 rather paler. The ears, except for a portion of their outer rims, are 

 distinctly margined with clear white. The throat and chest are of 

 a sordid white. 



The present dentition of this animal consists of six well-developed 

 incisors above, and six below ; and two upper canines appear to have
