tolerably long-, ami will ilcvelopcd. I'osterior pair of plcopoda

I'ho specimens that I have prociu-cd agree in every particular with 

 Leach's veiy meagre description in the ' Edinb. Encyc,,' both as to 

 colour and the form of the gnathopoda, and resemble M. -Edwards's 

 figure and descrijition of Amplutlioe Jxrinii . Eut M. -Edwards states 

 that P. fuclcoJa difters in " the great inequality which exists in the 

 fii'st and second pairs of gnathopoda," which is evidently an error, 

 since Leach classifies it with those that have " foui' antei-ior feet with 

 a fihform hand." 



7. Pherusa Barretti, n. s. (Piate XXVII. fig. 10.) B.M. 



Cephalon produced into a small depressed rostrum. Third segment 

 of the pleon ha^dng the posterior margin laterally produced near 

 the middle into a long upcurved tooth. Eyes large, subreniform. 

 Superior antennae one-third as long as the animal ; peduncle stout 

 at the base, having the first joint distally produced interiorly ; 

 second and third joints not so long as the first. Inferior antennae 

 someAvhat longer than the superior ; peduncle having the fourth 

 joint reaching as far as the extremity of the peduncle of the su- 

 perior. Gnathopoda minute, uniform. Posterior pair of pleopoda 

 not exceeding the penultimate in length. In other respects the 

 animal resembles P. fucicola ; and it may, without close examina- 

 tion, be mistaken for Ati/lus inermis. 



Length about | an iueh. 



Hab. North Atlantic {Mr. Barrett). 



It is named in compliment to the industrious natiu'alist who 

 discovered it.

Cephalon vaulted. Eyes prominent. Upper antenna not so long as 

 the lower ; thii'd joint of the peduncle scarcely distinct from the 

 flao-ellum. Mandibles having an appendage. Gnathopoda sub- 

 chelate, small, feeble, submembranaceous ; second pair not larger 

 than the first. Posterior pair of pleopoda biramous. Tel son single. 



This genus appears to be closely allied to Dexamhie and Att/hts :
