XVIII. — Beply to Dr. Gray on Testudo chilensis &c. 

 By P. L. SCLATEE, Ph.D., F.Pt.S. 



To the Editors of the Annals and Magazine of Natural Historif. 



Gentlemen, 



Dr. Gray, following his habitual practice, has thought 

 proper to reply to my scientific criticisms upon the species de- 

 scribed by him as Ateles Bartletti and Testudo chilensis with 

 a series of personal remarks which I do not care to notice. 

 As, however, one of the charges made against me would, if 

 true, affect the credit of this Society, I request you to publish, 

 in answer thereto, the subjoined account of some observa- 

 tions on this subject made at the meeting of this Society last 

 evening. 



I may also as well state that it is not correct that (as 

 assumed by Dr. Gray) my information as to the synonyms of 

 the (so-called) Testudo chilensis was obtained from Dr. Gray's 

 " short note." 



I am. Gentlemen, 



Your obedient Servant, 

 Zoological Society of London, P. L. SCLATEE. 



II Hanover Square, London, W. 



January 17th, 1871. 



" On concluding my series of reports upon the additions to 

 the Society's menagerie for the past year, I beg leave to take 

 this opportunity of calling the attention of the meeting to the 

 register of accessions to the menagerie now lying on the table.
