brush of very long hairs. The hand is long and narrow, 
and fringed on both margins with a few hairs ; the palm 
is very oblique and not defined ; the finger is short and 
much curved. 
The rest of the animal appears to bear a near re- 
semblance to M. gryllotalpa . 
The specimen from which our figure is taken was 
damaged, the inferior antennae and last pair of walking 
legs being broken off. By an error one of the latter is 
figured as being present, but it is drawn considerably too 
short, most probably it is of the same dimensions as that 
in the other species. The specific name also, proposed in 
allusion to the fascicle of hairs on the second pair of 
legs, has accidentally been incorrectly printed, but its 
proposer considers that there is less liability of con- 
fusion if the original name, though established by 
accident, be retained, than if it were now to be altered. 
The animal is of a horny colour, gradually passing 
into a gray tint along the dorsal surface. 
It was dredged by us near Plymouth, in company with 
our friend Mr. H. Stewart.
