186 Miss H. Richardson on the Isopods of the 



Tlie terminal segment, has a large sinus in which are situated 

 six sharp teeth. At the base of the sinus is a large tubercle. 

 Three double tubercles are also 

 found at the base of the terminal 

 segment. The inner branch of 

 the uropoda is affixed to the sides 

 of the abdomen and extends two 

 thirds of its length ; it is tri- 

 angularly pointed at its extremity. 

 The outer branch is long and 

 slender, almost cylindrical in 

 shape, smooth, somewhat incurved, 

 and extends much beyond the tip 

 of the terminal segment. 



The legs, all ambulatory, are 

 slender, with dactylus uniungui- 

 culate. 



Specimens were dredged off Ciliccea caudata <jilliana. x 8. 

 Catalina Island, California. 



Type. No. 2257G, U.S. N. M. 



These specimens differ from Ciliccea caudata (Say)* in 

 the presence of six distinct teeth within the sinus of tiie 

 terminal segment, while in that species there are but four ; 

 in the greater development of the spine at tiie base of the 

 sinus ; and in the median double tubercle at the base of the 

 terminal segment. 



33. Ciliccea granulosa, sp. n. 



Surface of body densely granulated ; granules large and 

 close together. 



Head with anterior margin thickened, and produced in a 

 small median point, on either side of which the margin is 

 lobed. Eyes situated post-laterally. First pair of antcnnge 

 extend to the posterior margin of the first thoracic segment ; 

 first joint of peduncle oblong ; second joint short. Second 

 pair of antennai extend to the posterior margin of the third 

 thoracic segment. 



The first thoracic segment is longer than any of the 

 following segments. The cpimera are twice as broad as 

 long. 



The first abdominal segment is short and bears indications
