Sphyrocephalus labrosus, sp. nov. 



Brown, with a few whitish hairs at the base of the ears. The 

 head very large, massive, half as long as the whole body, oblong, 

 and as broad at the muzzle as at the top of the head, with some re- 

 semblance to a hammer, whence the name hammer-headed {Sphyro- 

 cephalus), rather more than twice as long as deep ; ears rather large, 

 destitute of tragus ; eyes rather large ; eyelids provided with eye- 

 lashes ; nostrils large and tubular ; lips extraordinarily developed ; 

 both upper and lower lips of a veiy smooth semi-muco-membranous 

 texture, corrugated and tuberculated at the margins ; the upper lip 

 with a tuberculated prominence in the line of the two outer incisors, 

 and a more elongated tuberculated ridge further up, in the line of 

 the two inner incisors ; the external lateral margin expanded into a 

 sort of stiff semi-cupshaped flap with a tuberculated edge, rising to 

 meet the nostril and then descending, following its lower edge, and 

 terminating in a curved scroll-like coil in the nostril. 



The same semi-muco-membranous lip is spread over the front 

 of the lower jaw, forming a sort of chin. The skin in the neigh- 

 bourhood of the lips, and extending upwards and backwards along 

 the nasal bones, is covered with the same sort of fine velvety down 

 which surrounds a horse's nostrils ; the hair on the rest of the head 

 is flocky ; on the downy portion there are on the sides of the upper 



* Since this paper was in print, the last number of the ' Proceedings of the 

 Academy of Natural Sciences of Philadelphia' has been received in this country 

 (the iirst copies arrived on 19th February, 1862) ; and in it I find a description of 

 a new Bat, which probably belongs to this species, by Dr. Harrison Allen (Proc. 

 Acad. Nat. Sc. Phil. July 1861, p. 156). It is said to be taken from a specimen 

 collected by M. Du Chaillu, and is named by Dr. Allen Hypsignathus monstrosus. 

 If it is the same species, of course Dr. Allen's name must take precedence. His 

 description does not quite correspond with mine, but, judging from the description 

 of the nose, may, perhaps, have been taken from a dried skin, whereas mine is 

 from a fine example in spirits. M. Du Chaillu has exhibited no specimen of this 

 Bat in England.
