of anterior margin ; third joint short ; fourth about twice as long as 

 broad, subrectangular ; wrist small, triangular, broader than long 

 with many long setae on convex posterior margin ; hand very large, 

 subrectangular, twice as long as broad, with palm oblique and hav- 

 ing moderately deep notch near middle, prehensile angle with stout 

 spine, palm provided with numerous submarginal setae, posterior 

 margin with 6 fascicles of setae and apex with 5 or G long setae ; 

 finger curved, stout and of usual form. 



Pereiopods with epimera of moderate size, of usual form and 

 provided with dactyls but no spinning glands. 



Uropods .3 pairs, biramous ; first extending slightly be3'ond second, 

 rami cylindrical, inner one slightly longer than outer, peduncle ^/s 

 longer than rami, provided with sharp spines on inner margin ; 

 second uropods of essentially same form as first but with peduncle 

 much shorter so that rami are slightly longer than peduncle ; terminal 

 uropods reaching much beyond the others, rami very long, equal, 

 laminar, finger with spinules, apices narrowly truncate. 



Telson flat, slightly longer than broad, with lobes widely separated, 

 cleft ^/a to base ; each lobe terminating in long acute process and 

 bearing 2 long stout spines side by side on inner margin near apex. 



Length 6 mm. 



The species was represented by a number of specimens some of 

 which were found in sand at Flatts Village from low water to 

 2 fathoms. 



The species has been reported previously only from the Medi-

Ceradocus parkeri sp. nov. 



Eyes, small round, compound. 



First antennae long and slender, about 1/3 as long as bodj-, with

 is made up of about 20 segments which are provided with long 

 setae; accessory flagellum half as long as principal flagellum, made 

 up of 6 or 7 segments ; peduncle with first 2 segments cylindrical 

 and equal in length, third joint less than 1/5 as long as second and 

 narrower. Second antennae about ■'/s as long as first, with short 

 flagellum made up of about 8 short segments, slightly shorter than 

 last joint of peduncle, which in turn is about '^/a shorter than the
