PONTELLIN2B. 71 



in the male as long as the last two. The third and 

 fourth abdominal segments in the male each bear a 

 sharp projecting spine on the right side, and the last 

 thoracic segment is produced downwards into a hook- 

 like spine. The caudal setae are not as long as the 

 abdomen. Length of the animal -p^th of an inch 

 (1*5 mm.). Colour dark brown. 



This species is at times taken in great abundance 

 by the surface net. I have a gathering taken in this 

 way by Mr. B. C. Davison off the Yorkshire coast, 

 which more than filled a four ounce bottle, and con- 

 sisted of about equal quantities of P. brevicornis, Ano- 

 malocera Patersonii, and larval decapods. I have also 

 notes of its occurrence in surface gatherings from 

 Bridlington Bay, the Channel Islands, Westport Bay 

 (Ireland), and Kinsale Harbour; in gatherings made 

 amongst Algae and Zostera at Clifden Bay and the 

 Scilly Islands, as well as in tide pools on the Durham 

 coast ; also in dredged material from Cumbrae and 

 Portincross, Firth of Clyde. 



Sub-family 2. PONTELLINJE, Dana. 



Having two or more paired lateral eyes, in addition 

 to a large median eye which usually springs from 

 behind the rostrum as a projecting globe; in other 

 respects like Calanince.
