418 THE ZOOLOGIST. 
mouth, for the following remarkable observation :—‘‘ This species, 
though known to be common in Swanage and Studland Bays, 
immediately opposite Bournemouth, is scarcely ever thrown up 
on the beach at the latter place; but in July, 1875, an enormous 
number occurred, forming a little bank, and comprising many 
thousand specimens. Some of them were very large, and many 
in a soft state after change of skin. All were thrown up dead. 
I could never hear of any occurrence in the neighbourhood to 
account for this wholesale destruction. If it had been the result 
of submarine explosion or the like one would have expected to 
find other species, dead fish, &c., amongst them; but nothing 
besides Maia squinado was there, beyond the usual casual speci- 
mens that turn up on the beach. Nothing of the kind has 
happened since, to my knowledge.” 
Eurynome aspera, Leach. 
This beautiful little crab terminates our British list of 
“spiders,” or triangular carapaced Crustacea. It is an elegant 
species, and of a pleasing bright colour. Its carapace is usually 
about three-quarters of an inch in length and proportionately 
broad; it is extremely spinous and tuberculated, as also indeed 
are its legs. The rostrum is large in proportion to the size of the 
animal, and divergent; the anterior pair of legs are remarkably 
long, and the fingers are somewhat curved. The abdominal seg- 
ments are carinated and tuberculated, those of the female being 
much broader than those of the male. 
Prof. Bell remarks that this species is a deep-water one; it, 
however, is not entirely so, for we have obtained it fairly plentiful 
from the bays of the Channel Islands. 
It has been recorded from St. Andrews, rare; Dublin, rare; 
Shetland, rare; Plymouth; Galway, common; Belfast; the 
Hebrides; Moray Firth; Isle of Man; Hastings; and the Cornish 
coast. So that it is very generally distributed. 
The ova of this species present no particular feature; they are 
exuded about June, and are of the usual orange colour, becoming 
darker as the development of the enclosed zoza proceeds. 
The carapace being thick, and the size of the animal small, spe- 
cimens may be dried without disarticulation, provided care be taken 
to keep them from the light of the sun or from too much heat.
