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

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



Class CRUSTACEA. 

 Fam. Crangonid^. 



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, bun-owing in the sand, or rather sinking into it, by 

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



Class ANNELIDA. 

 Fam. Amphinomid^. 



Euphrosyne foliosa (Aud. at 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-
