 at low water mark. 



LANGOUSTIANS. 



GENUS PALINURUS: the body almost cylindrical; in 

 front a deep depression, having on each side a prominent 

 spine, with others scattered about. The legs one-fingered. 



CRAAVFISH, RED CRAB. P. Vulgaris. M. Edwards' 

 Crust., vol. 2, p. 292. Leach's Malac, pi. 30. Cancer 

 Homarus, Pennant, pi. 11, fig. 22. 



A large and valuable species, inhabiting along the borders 

 of rocks, where it is often taken in Crab pots; which however 

 its long and unyielding antennae frequently hinder it from en- 

 tering. Keeping in companies it also gets entangled in the 

 Trammel Net, and in some abundance on the fishermen's 

 lines. 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 foliaceous ; 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 foliaceous ; second pair of legs didactyle, 

 the third pair slender and not enlarged at the end. Cara- 

 pace with a slightly projecting snout. 



SLOW SHRIMP. A. Stirynchus, MJEdwards' 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 

 the 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- 

 lianassa, has the habit of burrowing in the sand, from which 

 it 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 

 spawn, was dug out of the sand in the middle of summer. 



GENUS GEB1A : carapace terminating in a rostrum large 

 enough to conceal the eyes, the sides forming a ridge pass- 

 ing back and encircling the region of the stomach. Outer 

 antennae without a scale. Abdomen long, more enlarged
