Hub. China. 



This fine Ape was presented to the Society on the 15th instant by 

 Miss Charlotte Alice Winkworth, of 65 Gloucester Crescent, Regent's 

 Park. Miss Winkworth received it from a relative in Shanghai, 

 who sent the following account of the animal : — 



" The Ape is about three or four years old, a fine male ; he comes 

 from the province of Szechuen, in China, and is probably the fiist 

 conveyed home from the interior of China. In the winter he has a 

 splendid coat of rich brown hair, very long and thick ; and is very 

 fierce and powerful." 



The canines are either not much developed, or they have been 

 broken out, perhaps in some eucounter with the wires of his den. 



3. Observations on the Margined-tailed Otter [Fteronura 

 sandbachii). By Dr. J. E. Gray, F.R.S., V.P.Z.S., &c. 



(Plate VII.) 



During the first visit of the British Association to Liverpoolin 1837 

 I observed a dej)ressed-tailed very large-footed Otter in the Mu- 

 seum of the Royal Institution of that town, which had been collected 

 in Demerara by Mr. Edmondson, and presented to the Museum by 

 my friend Mr. Sandbach. I brought it before the Natural-History 

 Section, and nained it Pteronura sandhachii. 



A descrijttion of the specimen was publislied in ' Loudon's Maga- 

 gine of Natural History' for 1837, i. 580. 



Mr. Gould kindly made me a drawing of the specimen during the 

 meeting, whicli was engraved, with some notes on the genus, iu the 

 ' Annals and Magazine of Natural History' for 1839, ii. 285, t. 14. 

 This plate is copied in Wiegmann's 'Arciiiv ' for 1838, p. 392, t. 10 

 (which did not a|)pear until late in 1839). 



Professor Wiegmann at first doubted the distinctness of the genus 

 from Eiihydru, but after he received the plate admitted that the 

 genera were distinct . He })roposed to alter the name of the genus 

 from I'terunuru to Pteruru.
