MAMMALIA CHIROPTERA. 21 



Tschudi has noticed (Miiller's Archiv, 1843, p. 471) a peculiar distribution 

 of the radial, crural, and middle sacral arteries in Layothrix Ilumboldti. 



PROSIMII. The Lemur coronatus has now been figured 

 by Gray (1. c.), and proves to be a distinct species. 



P. Gervais, in the Diet. Univ. d'Hist. Nat. iii, under the article Cheiro- 

 yidcus, has more precisely characterized Lemur furcifer, Blainv., nearly allied 

 to Ch. milii. Of Lesson's four genera, Cebiiyale, Myscebus, Gliscebus, and 

 Myoxicebus, he says : " ils doivent etre considered comine non avenus, 

 puisqu'ils font tous double emploi." 



Otolicnus Teng, Hedenb., lias been declared to be a new 

 species from Sennaar by Sundevall. (K. V. Acad. Handl. 

 1842, p. 201.) 



0. cinereus, "subtus albus, caudaciucreo-uigricaute; digito posteriore quarto 

 longiore." In 0. moholi, as stated by Suudevall, the tail is said to be 

 shorter, bare, and especially the third and fourth fingers of the posterior 

 hand of equal length, and a little exceeding the fifth. 0. senegalensis is said to 

 differ in the paleness of the colour, above, beneath, and on the tail, as well 

 as, according to Smith, in the uniform colour of the hair on the belly. 



The Munich collection is indebted to Dr. Pruve, also, for some specimens 

 from Sennaar, which differ from those of Hedeuborg in this respect, that 

 they have but little white beneath, but are rather of a lively yellow ; their 

 back even is clashed with a light yellow tint, which is, however totally want- 

 ing on the tail. The length of the toes is exactly as stated by Suudevall. 

 Consequently, since the colour in the specimens from Upper Nubia is vari- 

 able, and the length of the toes in dried specimens is not always to be taken 

 as accurate, I still retain the opinion that no specific distinction exists 

 between 0. Teng, molioli and senegalensis, or at least that it has not been 

 rendered evident. 



Eraser remarks (Ann. Nat. Hist, xii, p. 437), that his specimen of Galago, 

 from Cape Coast (West Africa), was shot in a tamarind tree, near the top of 

 which it had built its nest of loose leaves in the fork of a branch. The eyes 

 were large and prominent ; the motions of the animal slow.

FRUGIVOKA. In the Zoology of the Voyage of the 

 Sulphur, p. 28, J. E. Gray has given a synopsis of the 

 genera which he assigns to his tribe Pteropina, as follows : 



(ft) Wings from the side of the back ; head very long, pointed ; no tail :
