excuse. The present specimens agree in every respect with Dr. 

 Leche's figure and description of " G. damarensis," and also, except 

 in being a little darker coloured, with the type of G. ochraceo- 

 cinereus.

The peculiar fimbriation of the lower sides of the spines in this 

 species, previously noticed by Waterhouse \ is unusually well-marked 

 in these specimens, the spines being as it were finely feathered on 

 their edges and inferior^ surfaces ^ This animal is one of the most 

 distinctly West-African forms in the whole collection, the genus 

 Atherura being, so far as Africa is concerned, entirely confined to 

 that district, and only reappearing again in the Malay part of the 

 Oriental Region.

" Iride fusca."— E. 



Fur long, extraordinarily soft and fluffy. General colour pale 

 yellowish white, wholly different from that of any other species of 

 the group, and indeed scarcely to be matched as a general body 

 colour in any other mammal ; its tint all over the body something 

 like that of the centre of the belly of D. arboreus. Hairs of upper 

 side dull brown for three fourths of their length, their tips pale 

 yellow, whiter on the head, deeper yellow on the rump. Hairs of 

 underside and limbs similar, but the brown gradually decreasing in 

 extent downwards, those of the chin, chest, and belly wholly pale . 

 yellow ; cheeks, a ring round each eye, hands and feet, and hairs on 

 ears white ; hairs of the dorsal spot also white. 



This most remarkable species is unfortunately only represented 

 by a single young individual, in which the milk-dentition is still in 

 position. The only adult dimension that I am able to give is, there- 

 fore, that of the first true molar (7 "2 millim. long externally, and 5' 6 

 broad anteriorly above, and 6*6 long below) ; but comparing the 

 specimen with equally young individuals of D. arboreus, it is 

 evident that its size when adult would be just about the same as 

 in that species. Its actual dimensions are : — Head and body 295 

 millim.; hind foot 48 ; ear (above crown) 13. Skull — basal length 

 55; interparietal length 11, breadth 16-2; diastema between in- 

 cisors 4 "7, behind incisors 5 '3 ; lengths of upper milk premolars ;

^ Prof. Stewart has been kind enough to examine the fringes on these s])ines 

 microscopically for me, and he tells me that "they are only extensions of the 

 cuticular layer of the spines. On the under surface of the spines they are thin 

 and scale-like, becoming simple and hair-like at the margins."
