The Amphipoda of Bermuda. 113 



palm olilique, forming- nearly entire posterior margin, provided with 

 numerous short setae ; finger rather long and curved, concave mar- 

 gin somewhat serrated. 



Second gnathopods with second joint long and slender and slight- 

 ly curved so that posterior margin is slightly convex, anterior apex 

 produced to form acutely pointed process ; third joint about as 

 broad as long; fourth joint spheroidal, articulating with third joint 

 by rather slender stalk, provided with a few setae posteriorly ; wrist 

 very short, triangular ; hand strongly developed, oval in form, broad- 

 est about ^/a distance from proximal to distal end, palm extending 

 to very near proximal end of posterior margin and somewhat in- 

 cised, posterior margin separated from palm by rather prominent 

 triangular process which bears apically a stout spine, form of palm 

 variable, but always with deep U-shaped notch toward distal end ; 

 linger very long and curved. 



First and second pereiopods rudimentary and 2-jointed. Branchial 

 vesicles confined to third and fourth thoracic segments, long and 

 oval in form. Third, fourth, and fifth pereiopods developed normally. 



Abdomen made up of 2 segments. Uropods, only one pair which 

 are very short and 2-jointed, with the terminal joint exceedingly 

 small and rounded, the iirst joint broader apically than proximally 

 and bearing several setae apically. 



Length 9 mm. 



The species was represented by numerous specimens received 

 from Dr. L. J. Cole and bearing the date July 15, 1903. 



According to Pearse this species was abundant in the Gulf of 

 Mexico, off Northwest Channel, in 10^/^ fathoms. 



Pearse figures the second gnathopod of the male with the prox- 

 imal end of the hand broadened to form a triangular process and 

 with the palm bearing a very large triangular notch. In the speci- 

 mens from Bermuda the second gnathopod of the males does not 

 differ from that of the females which corresponds with that figured 

 by Pearse. 



Cyamus fascicularis Verrill, 1903. 



1903. Trans. Conn. Acad. vol. 11, p. 21; pi. 8, fig. 4. 



A slender bodied Cyamus from the body of a young sperm whale, 

 taken off Bermuda and exhibited at St. George's in April. 



" This species is much more slender than those of the right whales 

 and allied cetaceans. The two branchial segments are about as 

 wide as the following ones, and bear fascicles of small, short, some-
