as well as the terminal spine of the exopod, are long, slender, and 

 serrate or piumose. 



Male. A male specimen 3.7 mm. long which I refer to this 

 speeies is not in sufficiently good condition to he figured. The 

 carapace is less deep than in the female, the pseudorostrum more 

 horizontal and the spines ou the surface of the carapace mostly 

 reduced to tubercles. The spines on the dorsal surface of the ab- 

 dominal somites however are even longer than in the female. 



Remarks. This speeies differs remarkably from ali the de- 

 scribed speeies of the genus in the spinose armature of the carapace. 

 Nevertheless the structure of the mouthparts shows it to be a true 

 Campylaspis , though it appears to be exceptional in having the 

 ischium of the second maxillipeds distinct and in the imperfect 

 development of the branchial apparatus.

 As I bave already noted, these specimens show more distinctly 

 than do those from the West of Ireland the double dorsal keel on 

 the posterior thoracic and anterior abdominal somites.
