246 REPORT ON ZOOLOGY, MDCCCXL1V. 



a thick transparent vitelliue membrane, that contained the small granular 

 contents and germinal vesicles ; their diameter amounted to about 5 gjth of an 

 inch. Under the name Cercopitliecus Samanr/o, Wahlberg has established a 

 new species of Monkey. (Hornschuch, Archiv. Skandinav. Beitr. z. 

 Naturgesch, I, S. 179.) It belongs to the largest species, and is charac- 

 terized as follows : C. cinereus ; pilis flavesceute variegatis, capite nigro, 

 pallide punctate, absgue fascia frontali pallescente ; brachiis totis uigris. 

 Mas adultus lougitudiue ad basin caudse in. 59 ; caudee lougit. 0,77. 

 Fades nigricaus genis totis dense pilosis, colore corporis. Labium superius 

 usque ad nasum et iuferius cum meuto sparse albidopilosa: ; macula ante 

 geuas nigra. Aures intus et margiue albidopilosa?. Gastreeum pallescens. 

 Pili gula? et juguli lanati, densi, breves, albicli. Antipodes tautum in antica 

 hurnerorum parte variegati. Pedes posteriores extus obscure ciuerei, albido 

 variegati. Manus omnes nigri. Cauda a basi ad medium albida, linea supe- 

 riore fusca; dein sensini nigra. Femina parum minor, similis mari. Dis- 

 covered by Wahlberg in great numbers in Caffhiaud, at an inward latitude 

 from Port Natal. 



In the ' Ann. of Nat. Hist/ xiv, p. 361, Templeton has 

 contributed some good observations made upon Innus sinicus 

 in its own locality, and regarding its specific place.. 



It is found throughout the western and southern coast provinces of 

 Ceylon, and is easily distinguished from I. radiatus by the bright tan hue of 

 the face and the black rim of the lower lip. The diversities of age and sex 

 are closely delineated. 



SIMI.E PLATYRKHiNvE. J. vouTschudi has, in the 'Fauna Peruana,'S. 23, 

 demonstrated the existence of 9 genera, with 20 species of Apes, in Peru. 

 All these Apes are distributed also through other regions of South America, 

 yet several of them may be set down as peculiar to Peru, from their attain- 

 ing the maximum of frequency in this country, and being, so to speak, 

 dispersed in different directions from it as from a common centre of origin. 

 Tschudi lays particular stress upon Layothrix Humloldti, together with 

 Ateles ater and marginatus, which extend north and eastward from Peru 

 into the adjacent tracts of land ; the remaining species, however, may be 

 regarded as having migrated from the former territory. 



Of the genus Ateles, Tschudi represents in the above ' Fauna' four 

 species; viz. A. marginatus, ater, paniscus, wdpentadactylus. He has only 

 once seen A. marginatus, but, on the other hand, A. ater more frequently. 

 In the latter species the colour of the face is a deep black merging into a 

 coppery hue, and is then difficult to distinguish from A. paniscus. As dis- 

 tinctive characters for A. ater, Tschudi adduces the following : eyes placed 

 further apart, muzzle more rounded off, the five extremities much longer in
