STALK-EYEHD CRUSTACEA OF GREAT YARMOUTH. 181 
Stenorhynchus rostratus. Beaked Spider Crab. C.—Taken 
in shrimp-nets. 
__ SS. tenuirostris. Slender-beaked Spider Crab. C.—A common 
take in the shrimpers’ nets all the summer. 
Iithodes maia. Thornback Crab. K.—Known to fishermen 
as ‘Camperdown Pilots.” Most of those seen in fish-shops are 
brought from the west coast, or from the other side of the German 
Ocean. Trawlers only bring it in as a kind of curiosity. The 
dried shell is frequently seen in local fish-shops as a window 
attraction. Is never eaten here. It has been dredged up in the 
neighbourhood. 
Hyas araneus. Harper Crab. C.—Frequent on the beach in 
winter time ; numbers sometimes washed ashore in frosty weather, 
when it is seen feebly struggling, not uncommonly on its back, 
and often heavily berried. Is not at all common in the warmer 
months. I have frequently found freshly-moulted examples on 
the sands. 
H. coarctatus. F'.—Occasionally washed up on the beach. 
EHurynome aspera. K.— The only record I have of this 
species is one taken out of what I am assured was a locally-taken 
eod-fish, Oct. 7th, 1889. It was in company with Portumnus 
variegatus. 
Pirimela denticulata. Toothed Crab. F.—This pretty little 
Crab appears to be fairly common, its small size, grey hues, and 
retiring habits shielding it from casual observation. I first met 
the species Oct. 9th, 1889. Several times since found on the 
piles, and amongst seaweed. 
Pilumnus hirtellus. Hairy Crab. R.—As arule this species, 
I think, merits the title of a rarity. It is seldom found in perfect 
condition. On Noy. 25th, 1892, I picked up half a dozen on the 
north beach within the space of a fewyards. They had evidently 
been brought hither from the rough ground at Cromer by strong 
tides. 
Cancer pagurus. Edible Crab. F.-—-There is no harbour 
Within my “ten mile limit” for this species. Those found 
occasionally are undoubtedly driven hither by the strong sea 
currents following north-westerly gales. Have occasionally found 
small specimens amongst the drift at the high-water mark. 
By chance a fine example is taken in the shrimp-nets; on one
