ZOOLOGICAL SOCIETY. 



Sept. 26th, 1837.— Richard Owen, Esq. in the Chair. 

 Two small quadrupeds from the Society's collection were exhi- 

 bited by Mr. Waterhouse, who stated that he believed them to be 

 undescribed species. The first was characterized as 



Galago Alleni. Gal. auribus permagnis, digitis perlongis ; vellere 



intense plumbeo , rufescente lavato ; corpore subtus flavo lavato. 

 Longitudo ab apice rostri ad caudae basin, 8 unc. 1 lin. ; caudce, 

 lOunc. ; auris, 1 unc. 21 lin. : latitudo auris, 11 lin. : longitudo pol- 

 licis antipedum, 6 lin.; digiti longissimi, 1 unc. 1 lin.; pollicis pedum 

 posticorum, 7 lin.'; digiti longissimi, 1 unc. 2 lin.; pedis postici a calce 

 ad apicem digitorum, 2 unc. 11 lin. 

 Hab. Fernando Po. 



Obs. This specimen, which has four incisors in the upper jaw, and 

 six in the lower, is about the same size as the Galago Senegalensis, but 

 may be readily distinguished from that species by the greater size 

 of the ears, (the length of which is equal to the distance between 

 the tip of the muzzle and the base of the ear,) and the great length 

 of the fingers and toes. In the colouring there is also a difference, 

 G. Senegalensis being grey, washed with yellow ; whereas G. Alleni is 

 of a deep slate grey, all the hairs of the upper parts being of a rusty 

 yellow at the apex, or, as on the fore legs, rusty at the tip. The 

 under parts of the body are of a paler hue than the upper, the hairs 

 being of a dirty yellow colour at the tip ; but like those of the upper 

 parts, they are of a slate grey for the greater portion of their length : 

 on the throat and chin each hair is whitish at the apex. The hairs 

 covering the feet are of a deep brown colour. The tail is dusky 

 brown. 



Pteromys (Sciuropterus) Horsfieldii. Pier, fuscus, pilis flaves- 



centi-fuscis crebre intersparsis ; corpore subtiis fiavescenti-albo, 



genis et patagio lumbari ad marginem rufescenti-jlavis ; caudd 



subtus nitide ferrugined ; auribus mediocribus. 



Longitudo ab apice rostri ad caudse basin, 9 unc. 6 lin.; auris, 7 J 



lin.; tarsi digitorumque, 1 unc. 5 lin. 



Obs. This species is of a larger size than the Pteromys sagitta, from 

 which it differs in having the ears larger in proportion; the tail 

 more bushy and of an uniform bright rust colour beneath ; the mar- 

 gin of the flank skin is of a reddish yellow colour, as are also the sides 

 of the face below the eye. On the upper parts of the body the fur 

 is of a deep brown, each hair being grey at the base ; the inter-
