A common species, found of largest size on the rockiest 

 coasts, where it seeks the shelter of large stones and places 

 overhung with weeds. It prefers the stillest waters, advance- 

 ing and retiring with the tide; in Summer preferring water 

 that has a distinct feeling of warmth, and in winter going into 

 what is at that season less cold than at the margin, but never 

 far from land. 



It is sought after as a delicacy, the usual method of taking 

 it being with a bag net suspended from a circular ring of iron 

 at the end of a pole. Another method is by small pots, re- 

 sembling those employed for the Crab and Lobster. The 

 Prawn is a tempting bait for most sea fishes.

The FAMILY of STOMAPODS, 



Is formed of stalk-eyed Crustaceans that are destitute of bran- 

 chiae in interior cavities. It is divided into 

 CARIDIOIDANS, having legs formed alike, and fitted for 

 swimming ; the carapace reflexed against the base of the 

 legs, and again nearly covering the thorax, abdomen much 

 developed. 

 SINGLE CUIRASSIANS ; the legs various, the first large 

 and cheliform, the three next short and subcheliform, the 

 three last slender and natatory. Most of the thoracic rings 

 distinct, abdomen well developed. 



CARIDIOIDANS. 

 OPOSSUM SHRIMPS. 



GENUS MYS1S: The form slender and lengthened; scale 

 slender, on a long peduncle. Thoracic legs slender and 

 bifid, each anterior one shortest, abdominal paddles minute 

 and simple. 

 OPOSSUM SHRIMP. M. Spinulosus. M. Edwards' Crust, 

 vol. 2, p. 457. 



Common in summer, when it draws near the shallows from 

 deeper water: it also enters rivers in multitudes, forming a 

 long line of migration, at which season it is much devoured 

 by the Trout. Its English name is taken from its habit of 

 carrying the eggs in a receptacle under the thorax until they 

 are "hatched as in the analogous genus of Quadrupeds, the 

 Opossum tribe.
