CRUSTACEA OF NORTHUMBERLAND AND DURHAM 



Idotea linearis (Linne). 



Seaham in lo fathoms, 1861 (G. H.) D. 



Professor Sars has changed the usual spelHng of this genus 

 Idofea to Idothea. Such a change is not desirable, first because 

 Fabricius spelt his genus Idotea'^, and secondly because there 

 is a genus Idothea among the Mollusca. 



Fam. 2.— CIROLANID.^ 



EuRYDicE PULCHRA Leach. 



Occasionally taken in the tow-net in sandy bays near shore. 

 It seems to be more gregarious in habits than are the more 

 recently described species of the genus, which moreover are 

 usually found in deeper water. N.D. 



Fam. 3.— LIMNORIID.^ 



LiMNORiA LiGNORUM (Rathke). 



A very elaborate paper was published in 1893 by Dr. P. P. 

 C. Hoeck on the structure of this species, and on the damage 

 done by it in Holland"t. It is common on the Northumberland 

 and Durham coasts, and often does much injury to piles, 

 etc. N.D. 



Fam. 4.— ARCTURID.E 



AsTACiLLA LONGicoRN.is (Sowcrby). 



The Archniis gracilis of Goodsir and of Bate and Westwood 

 is the male of this species. 



Not uncommon off the coast. N.D. 



ASTACILLA INTERMEEIA (Goodsir).

 Philos. Jour., vol. xxxi., p. 309, pi. vi., figs. 1-3. 



1867. Arc turns intermedins, Bate and Westwood, Brit. 

 Sessile-eyed Crustacea, vol. ii., p. 271. 



* It is curious that Fabricius (Eut. Sy.«t. Supp., 1798) in the body of his work 

 pells his genus Idotea, but in the index it appears as Idothea.
