trum is more depressed; anteriorly, there is less 
development of the lateral branchial teeth, and 
there is a relatively greater distance between the 
fifth pair of pereiopoda. The pleon is almost 
circular, and covers the entire surface of the 
ventral region. | 
The colour of the animal is of a reddish-brown, 
which increases in brightness as it approaches 
towards the extremity of the chele. In one or 
two young females the carapace was smooth and 
glabrous. 
.Found in tolerable abundance in Esquimalt 
and Victoria Harbours, and, indeed, in all the 
sheltered inlets along the mainland coasts from 
the mouth of the Fraser to San Francisco. 
Dredged in about eight fathoms of water, but 
easily obtained in pools at extremely low tides. 
Its favourite haunt is under a large flat stone, or 
hid under the seaweed that fringes the margin 
ofa pool. The specimen from which the draw- 
ing was made was taken in Esquimalt Harbour.
