Two species of Cyclodoripf^c are known from .American waters : 

 C. agassi::ii and C. anfciiiiaria, l)oth described briefly by A. Milne 

 Edwards and later described in detail and figured by Milne Edwards 

 and Bouvier. Of C. agassizii, these authors recognized one varietal 

 specimen from off Havana ; the first Johnson-Smithsonian Deep-Sea 

 Expedition obtained three similar specimens in Puerto Rican waters. 

 This additional material ])ermits establishing that so-called variety as 

 a distinct s]iecies, to which the name hoiivicri is here given.

 Zool., vol. 27, p. 94 (part), 1902. 



Description. — Cyclodorippc bouvieri differs from C. ac/assicii as 

 follows : There is no spine on the protogastric regions ; the median 

 spines are tubular, not conical, and are higher than in agassicii; the 

 granulation is coarser on carapace and cheliped ; the margin of the 

 rostrum is arcuate, not angled ; orbit narrow in dorsal view, margin 

 rounding, orbital spine smaller than in the allied form. Wrist with a 

 prominent blunt outer tooth or spine near distal end and directed 

 forward. 



Type locality and distribution. — A male specimen from statirni [oo. 

 northeast of Puerto Rico, latitude i8°4o'i5" N., longitude 64°5o'i5" 

 W., 150 fathoms, March 4, i<;33. has l)een selected as the holotyi)e 

 (U.S.N.M. no. 67827). It has a carapace length of 5.2 mm and a 

 width of 5.6 mm. An ovigerous female was also taken in the same 

 haul. A second male siiecinien was taken at station 101. latitude 

 i8°45'4o" N., longitude 64°48' W.. in 300 fathoms. The specimen 

 that Milne ICdwards and Ijouvier thcnight represented but a variet} 

 of C. agassizii was dredged by the Ignited States Coast Survey 

 steamer Blake oft' Havana, Cuba (station ^;^) in 242 fathoms.
