 Between the typical Temorella affinis and the variety 

 hirnndoides — promoted by Prof. G. O. Sars to the rank of a 

 species — the differences seem to be of degree only, depending 

 upon the amount of development of the posterior angles of the 

 metasome, the hirsute furniture of the furca and some other 

 very slight variations. It seems better to look upon all these 

 forms as belonging to one and the same species. Our only 

 local record is "brackish water ditches at Hartlepool"

The British species assigned in the Ray Society Monograph 

 to Metridia arinata Boeck is saiil by G. O. Sars not to belong 

 to that species, but to J/, lucens Boeck. \\'e therefore adopt 

 that view, and are able to include it as taken off North 

 Sunderland, and also three miles off Ryhope (G. S. B.) N.D.
