4 Mr. G. S. Brady on the Non-parasitic Marine^ Copepoda 



process : in the male the feet are somewhat similar, but the 

 central joint is destitute of the spinous process, and the ter- 

 minal joint of the outer branch of one side is expanded into a 

 very broad lamina, which is terminated by a broad ciliated 

 seta. Abdomen of the female with four, of the male with five 

 segments. Length, exclusive of tail-seta, -y\ of an inch. 



Hah. Bridlington Bay ; several specimens taken in the 

 towing-net by Mr. E. C. Davison. On weeds in Koundstone 

 and Clifden Bays, Ireland [G. 8. B.). 



The most distinguishing characters of this fine species are 

 the auditory setse, with which the upper antennse are on their 

 basal portions thickly clothed, and the broadly laminar con- 

 struction of the fifth pair of feet, more especially in the male 

 sex.

This species occurs not uncommonly in surface-net gather- 

 ings from the open sea, but never in very great numbers, so 

 far as my observation extends. I accept Boeck's identification 

 of the species with C. typticus of Kroyer, but without the 

 opportunity of myself referring for verification to the original 

 description.

Of very frequent occurrence in surface-net gatherings from 

 the North Sea. I have also once taken it sparingly amongst 

 Fuci near low-water mark, between Sunderland and Ryhope.
