LESTRTGONUS KINAHANT. 9 



The inferior pair have the peduncle reaching beyond that 

 of the superior, and terminating abruptly, the flagellum 

 being considerably narrower, and somewhat shorter, than 

 that of the upper pair, although the articuli are similarly 

 formed to those of the superior. In all other respects 

 except, perhaps, in the less unequal length of the caudal 

 appendages the description of L. exulans will suffice for 

 this species also. 



The near resemblance of this species with that of L. 

 Fabricii (M. Edw.) of the Indian Ocean and L. rubescens 

 (Dana) of the Pacific, is quite as remarkable as that exist- 

 ing between L. exulans and a species from Chili. 



The first specimen which we received was sent to us by 

 Professor Kinahan, who captured it off Carrickfergus, 

 and in compliment to whom we have named the species.* 

 We have since received it in considerable numbers from 

 Mr. Edward, of Banff. 



The colour, as far as we can judge from the dead ani- 

 mals, is that of a salmon tint, with a few small spots of 

 dull red. The eyes are probably green. 



* It is with much regret that we learn, while this sheet is passing through 

 the press, that this able carcinologist has, at an early age, departed this life.
