CRUSTACEA. 487 



'* Common in crab boats. There appears to be two other species 

 on our coasts which. I have been accustomed to call JEsop's 

 Shrimps, from their habit of bending up the back into a hump, 

 but further observation is necessary to decide whether they are 

 known to naturalists." 



One of these is the following. 



Pakdalits thompsoni. — Bell, Stalh-eijed Crust, p. 290. 



Pandalus Jefireysii. — Spence Bate, Ann. JVat. Hist., and Brit. 

 Assoc. Rep., 1867,^. 278. 



Occasionally on rocky ground in about 6 fathoms of water. 

 Genus, Pal^mon. — Fair. 



" Carapace elongated into a serrated rostrum of considerable 

 length." First pair of antennae on three branches. First pair of 

 legs small, slender, chelate ; second pair larger and chelate. 



Pal^mon sereatus. — Common Prawn. — Pennant; Leach, Malac, 

 pi. 48; Milne Edwards, Sist. des Crust, t. ii, p. 389; Bell, 

 Stalk-eyed Crust., p. 302. 



''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, advancing 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 

 is with a bag net suspended from a circular ring of iron at the 

 end of a pole. Another method is by small pots, resembling 

 those employed for the Crab and Lobster. The Prawn is a 

 tempting bait for most sea fish." 



It inhabit all our coasts from about forty fathoms. 



PAiiiEMON SQUiLLA. — Linn., Fair. ; Leach, Malac, pi. 43 ; Milne 



Edwards, Hist, des Crust., t. ii, p. 300 ; Bell, Stalk-eyed 



Crust, p. 305. 



" Scarce, and generally confounded with the last named species." 



According to Leach it is tolerably abundant on the coast of 



Devon.
