ZAUS. 157 



angular; caudal segments large, about twice as long 

 as broad ; length of the principal tail- setae about 

 equal to that of the abdomen. Colour deep yellowish- 

 brown. The integument is marked with closely-set 

 subcircular foramina or pits, especially towards the 

 front of the body. Length of the animal Yrih of an 

 inch (1'5 mm.), greatest width ^g-rd of an inch. 



The following are the localities from which I have 

 notes of the capture of this species : Portincross 

 (Ayrshire), dredged in fifteen fathoms ; off Staiths, 

 Red Cliff, and Robin Hood's Bay (Yorkshire), thirty- 

 five fathoms ; Bridlington Bay, one specimen taken in 

 the surface-net. These localities, it will be seen, are 

 all except one on the Yorkshire coast ; and in each case 

 the number of specimens found was very small, so that 

 Z. G-oodsiri must be looked upon as one of the rarest, 

 as it is certainly one of the finest, of British Har- 

 pacticidse. 



Dr. Claus has identified this species with Good sir's 

 Sterope ovalis, and considers Sterope armatus of that 

 author to be simply the male of the same animal. I 

 am unable, however, to agree with this view. Goodsir's 

 figures, if meant to represent this species, are certainly 

 very unfortunate, showing in both cases an abruptly- 

 rounded abdomen, without any distinct caudal seg- 

 ments. Moreover, in 8. ovalis the anterior segment of 

 the body is stated to be as long as the entire length of 

 the remaining segment, and the posterior legs to be 

 armed on the lateral edges with strong spines, of which 

 the two terminal are the longest. Both these characters 

 are certainly incorrect as applied to the present species.
