J. R. KiNAiiAN on the Britannic Species of 



This species, first added to the Irish lists by William Thompson, from speci- 

 mens obtained by Doctor Ball at Bray, occurs not uncommonly to me in sandy 

 pools in the littoral zone : it is much rarer in the dredge, and I have not taken 

 it as a deep water species. 



Its characteristic stunted form, the truncated beak, and the smooth abdo- 

 men, distinguish it readily from all the British species known, and indeed from 

 all foreign species which have been described. The great extent of range given 

 above leaves little room to doubt that further research will bring it to light all 

 round Ireland.
