SCLATEE ON THE NORTHERN LIMIT OF QXTADEUMANA. 509 



species for more than six hours together, but having no large shot I 

 was unable to procure any.' Mr. Deppe told me afterwards that 

 this Ateles was the only Monkey he got during his whole stay in 

 Mexico from 1824 to 1827. 



I have had the opportunity of examining this specimen in the Berlin 

 Museum in company with Dr. Peters. It is an Ateles of a species 

 allied to A. beelzebuth of Brazil and A. liybridus of New Granada, 

 but probably referable to Ateles frontatus — Br achy teles {Eriodes) 

 frontatus, Gray, (Voy. Sulphur). However this may be, it indubitably 

 proves the existence of a species of this genus in Mexico, as far north 

 as between 18° and 19° N.L. That this Ateles ranges still further 

 north seems amply proved on the evidence of M. Auguste Salle — 

 the well-known Naturalist and traveller — from whom I have re- 

 ceived the following communication relative to this subject : — 



" La limitela plus nord on on trouve des Singes a ma connaissance, est l'Etat de 

 San Luis Potosi, aux environs du 23 e degre de latitude, dans le haut de la riviere 

 de Tampico egalement. On en trouve une espece dans les montagnes et lieux tres 

 deserts de l'Etat de Veracruz, aux environs de Cordova entre cette ville et Huatusco 

 par le 19°. Je crois que c'est un Ateles, je ne sais pas au juste. Quoique tres com- 

 miin je ne l'ai pas vu aux Galeries du Museum, mais je tacherai de vous en donner 

 le nom; a Cordova on les nomme Changos. A la cote entre Veracruz et Tampico 

 il y a de grandes forets ou en trouve. On dit qu 'il j en a deux cspeces dans l'Etat 

 de Chiapas." 



In G-uatemala Mr. Salvin informs me that Monkeys are rather 

 scarce and difficult to be seen, but that three species have been 

 described to him as existing there. Of one of them he has brought 

 home an imperfect skin, which appears to be that of an Ateles. 



In Nicaragua, M. Salle states that he found four species of Qua- 

 drumana during his travels. Examples of two of these were pur- 

 chased by the British Museum in 1848 through Mr. Cuming, and 

 are now in the collection. One of the species is an Ateles (probably 

 A. frontatus), the second is a Mycetes, described and figured by 

 Dr. Gray in the Proceedings of the Zoological Society for 1848* under 

 the name M. palliatus, and erroneously stated to be from Caraccas. 



Further south, in Costa Bica, Dr. Peters informs me that the late 

 Dr. Hoffman, who up to the time of his lamented death, worked 

 vigorously at the Fauna of this interesting region, met with three 

 species of Quadrumana and forwarded examples of all to Berlin, 

 namely, — ■ 



1. An Ateles, apparently the same as Deppe's Mexican specimen 

 — though varying in colour. " This species," writes Dr. Hoffman, 

 " varies very much in colour from red "" to grey. It is called Mono 

 Colorado, and has a flavour like mutton." 



2. Mycetes palliatus, Gray. 



3. Cebus hypoleucus, Geoffr., called in Costa Bica Mono caro 

 biancho. " It bellows like a dog," says Dr. Hoffman. 



The Zoological Society have lately received some living examples 

 of the Hapale oedipus, said to have been obtained from Chiriqui, and
