224 MR. P. L. SCLATER ON ANIMALS IN THE MENAGERIE. [Mar. 7, 



On the 30th of June, 1865, we purchased of a dealer in Liverpool 

 the only example I have ever met with of this very singular species — 

 easily known from every other memher of the genus I am acquainted 

 with by the long thin hairs of the body, and in particular of the head, 

 as described by Dr. Gray. Our specimen was an adult male. 



The animal died in the August following, and Dr. Murie contri- 

 buted to the ' Proceedings ' some further notes on its external ap- 

 pearance, and an account of its anatomy. Dr. Murie has given 

 accurate measurements of the typical specimen (which are altogether 

 omitted in Dr. Gray's description), and also describes the colour of 

 the face and adjoining parts, but has omitted to note that there is 

 a small tubercle representing the thumb in this species. 



The accompanying drawing (Plate XIV.), which may serve to 

 render this Spider Monkey more easily recognizable, has been taken 

 by Mr. Smit from the typical specimen, which is now in the British 

 Museum. 



It is much to be regretted that we do not know the true patria of 

 this Ateles ; but I have some reason to suppose it may be from the 

 northern coast of Columbia, as I am told that a black Spider Monkey 

 with long hair over its head is occasionally brought for sale into 

 Cartagena. 



C. Ateles variegatus, Wagner. 



In July last we received from the Hon. A. Gordon a young female 

 Spider Monkey, which I was at first inclined to refer to A. belzebuth 

 of Geoffroy *, but which having died, and having been acquired by 

 the British Museum, was described by Dr. Gray as the female of his 

 A. bartlettif. 



In my remarks on this specimen (P. Z. S. 1870, p. 068, and Ann. 

 N. H. ser. 4, vol. vi. p. 472) I have given my seasons for consider- 

 ing A. bartletti, Gray, to be a synonym of A. variegatus, Wagner. 



In his reply to my remarks (Ann. N. H. ser. 4, vol. vi. p. 18) 

 Dr. Gray says that he does "not think I have proveshniy case." 

 In order to do this, therefore, more completely, I accepted the kind 

 offer of Herr. v. Pelzeln to send me one of the typical specimens of 

 A. variegatus in exchange from the Imperial Cabinet of Vfenna, and 

 thus convinced myself and other persons interested in the question 

 that my views were correct {.

% See antca, p. 39. As regards some remarks of Dr. Gray (Ann. Nat. Hist. 

 Feb. 1871) on the notice of the exhibition of this specimen as given in our 

 printed minutes, I may be permit led to observe : — (1) What I exhibited was not 

 the typical specimen of A. variegatus, but a typical specimen, i. e. one of Nat- 

 terer's original examples, of -which he altogether obtained five. (2) This was 

 received by me in exchange from the Imperial Cabinet of Vienna, not loaned to 

 me by the Museum of Munich, as Dr. Gray assumes, /. e. p. 164. (3) The name 

 variegatus was not published only in a " miserable compilation," as Dr. Gray 

 calls Reichenbach's work (Ann. Nat. Hist. Jan. 1871, p. 18), but, as shown by 

 the synonyms given below, in the ' Transactions ' of the Bavarian Academy of 

 Sciences and in other well-known works.
