2. Paraphronima crassipes, Claus. 



The head is almost as long as deep, eqiialling tlie three 

 following pereional segments in length. The upper antennce 

 of the female are longer than half the head, in the male onlj 

 a little shorter than the head. The fourth pereional segment 

 is shorter than the first and second together (5 : 6). The se- 

 venth is longer than the fourth (15 : 13). The first and se- 

 cond pairs of pereiopoda are equal. The carpus of the first is 

 narrow, the tibia projects into a process; the second ends with 

 a slender dactylus and two spines, which are a little shorter. The 

 third and fourth pairs are equal, only a little longer than the 

 fifth and sixth (11 : 10). The seventh pair are as long as the 

 sixth. The first pleonal segment is a little longer than the seventh 

 pereional one. The sides are rounded. The pleon is as long 

 as the four preceding pereional segments. The peduncles of 

 the pleopoda are only a little longer than the rami. The 

 first pair of uropoda are shorter than the second and third.

(Fig. 2). 



The head as long as deep, equalling the four following seg- 

 ments in length. The pleon is as long as the four preceding 

 pereional segments. The first pair of pereiopoda shorter 

 than the second, witliout carpal process. The end of the 

 metacarpus of the second pair is spoon-shaped, with the 

 dactylus forming a chela. The third and fourth pairs, 

 equal, are the longest of all; the seventh pair is shorter than 

 the sixth. The peduncles of the two last pairs of uropoda 

 are very broad; those of the first pair are much narrower, 

 with the outer ramus very short and narrow.

4. Paraphronima californica, n. sp. 



The head a little deeper than long, equalling in length 

 the three following segments; the second pereional segment 

 is longer than the first. The pleon is shorter than the four 

 last pereional segments. The first pair of pereiopoda are only
