The head is shorter than tlie first tiu-ee perreonal segments together, and is twice as deep 

 as long. The penvon is globularly inflatcd; tlie last two segments are dorsally feebly 

 produced in the median line. The second pair of jjcraiojjoda are almost twice as long as 

 the first, and about as long as the third. The femur of the fifth pair is longer than 

 the carpus. The rami of the iiropoda have the margins sniooth; the outer ranius is much 

 shorter than the inner. The telson is obtiisely triangulär, and about a tenth part as long 

 as the peduncle of the last pair of uropoda.

Phronimopsis spinifera is easily distinguished from its hitherto kiiown coiigericrs 

 bv the deep head, the globularly inflated perajon, the great length of the second paii' of 

 pera^opoda, aud b)' the iiarroAv and not hirsute uropoda. 



Claus did not give any separate specitie diagnosis, but poiiited out the following 

 distinctions as being of specific value: the spine-like processes of the peduncles in both 

 pairs of antennas, and in the labrum, the angularly bent femora of the first two pairs of
