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 

 triangularly 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 uniunguiculate. 



Specimens were dredged off Catalina Island, California. 



Type.Odt. No. 22576, U.S.N.M. 



These specimens differ from Cilicaea caudata (Say), in the presence 

 of six distinct :,eeth within the sinus of the terminal segment, while in 

 that species there are but four; in the greater development of the 

 spine at the base of the sinus, and in the median double tubercle at 

 the base of the terminal segment. 



This species is named in honor of Pr. Theodore Gill, the distin- 

 guished icthyologist.
