J 872.] LETTER FROM PROF. J. REINHARDT. 797 



Mr. Sclater read the following extract from a letter addressed to 

 him by Professor J. Reinhardt, of Copenhagen, dated August 30th, 

 1872:— 



" In turning over the ' Proceedings,' I have seen and read your 

 valuable paper on the Quadrumana found north of Panama — and 

 take the present opportunity to offer a suggestion with reference to the 

 Ateles vellerosus, and particularly to the precise locality of this 

 species. 



" We have in our collection a full-grown female of a large Ateles 

 brought from Mexico, and presented to the Museum in 18-13 by the 

 late botanist Prof. S. Liebmann. I have hitherto considered it a 

 new species and given it a provisional name ; but when I saw your 

 beautiful figure of Ateles vellerosus, it immediately struck me 

 that our Mexican Monkey might be that species. It is true 

 our specimen is a much larger animal (total length 53") ; the yel- 

 lowish colour on the inside of the limbs does not extend so far 

 down to the hands as in your specimens ; and the whiskers offer 

 only a faint trace of the whitish colour which encircles the face of 

 your Ateles. But the difference in size seems not to be of much 

 consequence, as long as it is uncertain whether your specimens are 

 fully grown or not ; and the difference in colour is, upou the whole, 

 not more perplexing than that occurring in several other species of 

 Ateles. I myself have little doubt of the identity ; but, for the 

 purpose of enabling you to judge for yourself, I enclose a drawing 

 of my Ateles, made many years ago, shortly after it had been 

 stuffed. 



"Iu the notes communicated to me by my late friend Prof. Lieb- 

 mann, it is stated that the said Monkey was shot in the neighbour- 

 hood of the small place Mirador, situated not far from the volcano 

 of Orizaba in the State of Vera Cruz. This Ateles is common there, 

 and lives in small troops in the deep barrancas up to an elevation of 

 2000 feet above the sea. Furthermore he met with it in the eastern 

 parts of the State of Oaxaca ; it was to be found in the forests there 

 even up to 4000 feet, the same elevation to which the Tapir ascends. 

 But at the same time he expressly states that he never met with 

 this Ateles, nor indeed with any other Monkey, on the Pacific slope of 

 the great Cordillera in Oaxaca, and that, as far as he could learn, Mon- 

 keys are to be found on the western coast only south of Tehuantepec. 

 I therefore strongly suspect that Mr. Boucard had been misguided by 

 untrustworthy information, when he told you {anted, p. 5) that his 

 specimen was procured near Acapulco. It may have been sent to 

 him from that harbour ; but it has certainly been killed at some dis- 

 tant place on the eastern slope of the Cordillera. 



" Still one more remark, and I have done. If I am right in re- 

 ferring my Ateles to the A. vellerosus, and not to A. melanochir, 

 the only evidence of the occurrence of this last-mentioned species in 

 Mexico rests, so far as I can see, on the specimen sent by Deppe to the 

 Museum at Berlin. But, from your note upon the northern limits of 

 the Quadrumana in the New World (Nat. Hist. ftev. 1861, p. 507), 

 it seems that this specimen, in some respects, does not quite agree
