XXXV. — Notes on some new or little-known Marine Animals. 

 (No. 3.) By P. H. Gosse, A.L.S. 



Class CRUSTACEA. 



Fam. CRANGONIDiE. 



Crangon spinosus (Leach). The Spinous Shrimp. 



A specimen brought me Sept. 1st is slender as compared 

 with C. sculptus and fasciatus. Its ground colour is drab or 

 pale wood-brown, with a defined band of opake white across the 

 fourth segment, a much broader one across the front of the 

 carapace, and an irregular broad white band running down lon- 

 gitudinally on each side, so as to unite these two, leaving an 

 oblong mark of drab insulated in the middle ; a broad band 

 of which crosses the tail-plates. The under parts of the body 

 and the legs are spotted with crimson. 



Crangon trispinosus (Hailstone). The 3-spined Shrimp. 



This species was not uncommon early in June in Weymouth 

 Bay, but ceased to occur from that time until the end of August, 

 when half a dozen were again dredged. Some of them were an 

 inch and a half in length. Their colour consists of a vast 

 number of ruddy-golden stars closely set, interspersed with black 

 and pale specks, on a pellucid grey ground. On the fourth 

 abdominal segment there is a speck of pure opake white, in the 

 median line, near its hind edge : this speck, though occasionally 

 obsolescent, appears to me to be so constant as to be charac- 

 teristic. The manners of this Shrimp are exactly those of its 

 congeners, burrowing in the sand, or rather sinking into it, by 

 the rapid displacement of it by means of the false feet. 



Class ANNELIDA. 

 Fam. AmphinomidjE. 



Euphrosyne foliosa (Aud. et M.-Edw.). The Leafy Euphrosyne. 



A little worm which I presume to be this species, I obtained 

 by dredging in Weymouth Bay, August 9th. The minute an- 

 tenna at the tip of the caruncle appears to be flattened and trun-
