302 CATALOGUE OF THE SrECIES OF 



*#* We hear that the Zoological Society have recently added a 

 young male Ourang-outang to their menagerie, which promises to 

 do as well as the female which has now lived some time in their 

 possession, and continues in sound health. The new-comer is a 

 younger animal, not more than half the size of its companion. 

 Both have been cheerful and lively since their introduction ; and 

 their is every reason to look forward to their living to maturity.

 Dear Sir, 



As you have been kind enough to express a wish that I should send 

 you a zoological paper for insertion in your useful journal, I have great plea- 

 sure in enclosing you a monographic revision of the Genus Cylftereu of La- 

 marck, which I have found necessary to divide into several genera, and to 

 which I have added the description of the new species which are in the col- 

 lection of the British Museum, or in my private cabinet. 



Yours, very truly, 

 To the Editor of " The Analyst." John E. Gray.
