out of consideration the Echinodermata, in which Johannes 
Miiller’s acuteness everywhere recognized traces of bilateral 
arrangement, such are to be found amongst the Coelenterata, 
. for example, in the 12-rayed Philomedusa Vogtii, and in the 
young brood of the equally many-rayed Cunina Kollikeri. The 
radiate structure is exhibited, on the contrary, with the greatest 
strictness in many four-rayed Discophora, and in the biradiate 
Ctenophora, which therefore prove, even in this respect, to be 
true Coelenterata.

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 ; 
* 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 first 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. Se. Phil. July 1861, p. 156). Itis 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. :
