Homarus, Pennant, pi. 11, fig. 22. 
A large and valuable species, inhabiting along the borders 
rocks, where it is often taken in Crab pots ; which however 
Jts long and unyielding antenme frequently hinder it from en- 
uring. Keeping in companies it also gets entangled in the 
trammel Net, and in some abundance on the fishermen’s 
j'Ues. It meets a ready sale in the market, though not so 
highly esteemed for the table as the Lobster. 
GENUS CALL1ANASSA : the integuments, except of the 
claw legs, soft; caudal plates large and foliaceons; second 
pair of legs didactyle, of the third pair larger at their ends. 
BURYING SHRIMP. C. Subterranea. M. Edwards’ 
Crust., vol. 2, p. 309. Leach’s Malac., pi. 32. 
GENUS AXIUS: integuments moderately firm. Caudal 
plates large and foliaceons ; second pair of legs didactyle, 
the third pair slender and not enlarged at the end. Cara- 
pace with a slightly projecting snout. 
‘"'LOW SHRIMP. A. Stirynchus, M. Edwards’ Crust., vol. 
2, p. 311. Leach’s Malac., pi. 33. The male of what I 
judge to be the same species differs from the female, in the 
snout, which in my specimen of the latter was finely not- 
ched, and without the well marked longitudinal ridge of the 
former. The outer antennae of the male are furnished with 
a ridge of firm hair on their inward line, decreasing towards 
fhe point, which the female is without, and the former also 
has well marked brushes near the lateral edges of the ab- 
dominal rings. This species, like those of the Genus Cal- 
jianassa, has the habit of burrowing in the sand, from which 
>t rarely emerges ; and then it seeks shelter in a crevice 
covered with weeds, for it is sluggish in its motions, and if 
distant from a soft bottom in which to sink, incapable of 
escaping an enemy. A female, that I obtained loaded with 
was dug out of the sand in the middle of summer. 
GEB1A : carapace terminating in a rostrum lar"-e 
enough to conceal the eyes, the sides forming a ridge pass- 
,n S back and encircling the region of the stomach. Outer 
antennae without a scale. Abdomen long, more enlarged
