CALIFORNIA STALK-EYED CRUSTACEA. 87 



below; dactyls narrow, compressed, convex above, abruptly contracted 

 near the tip into a short, curved claw; in the three anterior pairs the 

 dactyls are shorter than the propodi and leave the lower margin nearly 

 straight; in the last pair the dactyl is much longer than the propodus, 

 much longer than the preceding dactyls, and has the lower margin con- 

 cave. The outer surface of the palm is brownish with light-colored 

 reticulations. 



Length of carapace, 10 mm.; length of first ambulatory leg, 9.5 mm. 



Width of carapace, 10.5 mm.; length of last ambulatory leg, 10.5 mm. 



Described from a single female specimen found by 

 Professor W. E. Ritter in the branchial cavity of a 

 species of Cynthia from Paget Sound. Collection of the 

 University of California. 



Genus Fabia Dana. 



Closely allied to Pinnotheres. Carapace smooth, more or less mem- 

 branaceous, not much broader than long, and marked by a pair of longi- 

 tudinal sulci which extend backward from the upper margin of the orbits, 

 enclosing between them the median area. Front not rostrated. Eyes 

 normal, not widely separated. Antennularyfossettes not widely separated. 

 Maxillipeds with the merus large and the ischium rudimentary; third 

 joint of the palp articulated on the inner margin of the preceding one. 

 Ambulatory legs subequal and rather slender; dactyls short. 



Type. — F. subquadrata Dana. 



This genus differs from Pinnotheres in no important 

 character except the longitudinal sulci on the carapace.

Carapace smooth, glossy, membranaceous, subquadrata in outline, with 

 the angles broadly rounded; the space between the longitudinal sulci is 

 longer than wide and slightly narrowed behind; antero-lateral margin 

 rounded and marked by a raised line. Front very short and turned
