222 BRITISH PARASITIC COPEPODA. 



Xo males have been observed. 



Habitat. — Parasitic on the skin of the hake (Merlnc- 

 cius vulgaris). The specimens were found adhering 

 to scales near the base of the pectoral and ventral 

 fins of a hake captured in the Firth of Clyde in 

 December 1899. The whole parasite was enveloped 

 in some soft, nearly transparent, jelly-like matter, and 

 at first sight had the appearance of a small roundish 

 mass of mucus, and thus easily escaped notice : when 

 preserved, the mucus assumed a whitish colour. Miss 

 Bainbridge {op. cit.) described some specimens found 

 on the skin of a hake, " purchased at Sheringham, 

 Norfolk."

Female, — Cephalothorax tolerably elongated, usually 

 deflected backward upon the genital segment, and 

 extending somewhat beyond its distal end. Genital 

 segment subquadriform, the postero-lateral corners 

 prolonged backward and slightly outward in the form 

 of narrow subtriangular processes, their width at the 

 base being equal to about half the length and with the 

 apex bluntly pointed ; genital segment exclusive of 

 the lateral prolongations about as broad as long. 

 Abdomen intermediate between the processes, com- 

 paratively rather longer than broad and bluntly 

 rounded at the end. Three shallow knobs at the 

 anterior end of the genital segment, on the dorsal 

 aspect, one on each of the flatly-rounded corners, and 

 one intermediate and somewhat behind the others ; 

 two similar but smaller knobs also present on the fore- 

 head as shown in the figure (PI. LXVII, fig. 4). 



Antennules nearly as in Clavella scombri, but the 

 antennae, which are three-jointed, are scarcely so
