34 BEITISH COPEPODA. 



as have come under my notice,are very minute, and have 

 probabty on that account been overlooked. By Glaus, 

 the inner branches of the swimming-feet are stated 

 to consist of two joints only, but in our British species 

 three joints are distinctly present. The visual organs 

 I have had no opportunity of examining in fresh 

 specimens and must, therefore, accept as correct Dr. 

 Glaus' description which, briefly, is as follows : The 

 frontal lenses are large and very convex, and approach 

 each other towards the median line ; much behind 

 these, in the lower portion of the cephalothorax, lie the 

 elongated rod-shaped pigment bodies, slightly curved 

 and converging towards their bases ; the median eye- 

 spot is single, as in Sapphwma, and in the case of C. 

 germanus (anglicus) shows a pigment-spot in the 

 form of a half x, and one (or two ?) crystalline lenses.
