220 BULLETIN 97, UNITED STATES NATIONAL MUSEUM. 



Range. — From ofT ^larthas Vineyard, Massachusetts, to off 

 Curacao, via Gulf of ISIexico; 100 to 280 fathoms. 

 Material examined. — See table on page 219. 



CYMOPOLIA FLORIDANA, new species. 



Plate 41, figs. 3 and 4. 



Type-locality.— O^ Sand Key, Florida; 120 fathoms; J. B. Hen- 

 derson, collector; one female holotj'pe (Cat. No. 503G2, U.S.N.^I.). 



Diagnosis. — Three lateral teeth. Second leg three times as long 

 RS width of carapace. Inner suborbital tooth short, hidden by the 

 lobe at the angle of the buccal cavity. 



Description. — Near C. cursor and C. gracilis^ but the carapace is 

 more quadrate, the postero-lateral margins being more transverse 

 and making less of an angle with the lateral margins. Tubercles 

 and granules of carapace distinct from one another and acutely 

 pointed; about 20 tubercles are large and are arranged as follows: 

 3 in a triangle on the mesogastric region; 2 cardiac, side by side; 1 

 intestinal; 4 in a row above the posterior margin; 5 on each 

 branchial region, of which 4 form a rhomb near the center, and the 

 fifth is near the cardiac region. Four acute teeth on frontal mar- 

 gin; those of middle pair slender, separated by a deep, V-shaped 

 sinus. Outer orbital tooth narrow, pointing nearly straight for- 

 ward; outer angle of preorbital tooth a right angle; the two superior 

 teeth of the orbit are subtriangular, the outer one the larger; inner 

 sinus U-shaped, other sinuses V-shaped. Three antero-lateral teeth, 

 small, sharp, rather spiniform, the hepatic tooth a little further 

 from the next tooth than the branchial teeth are from each other. 

 Outer suborbital tooth subtriangular, set off by large sinuses; inner 

 angle of orbit produced obliquely inward in a small, acute tooth 

 which is hidden by the large, lobiform, subacute, pterygostomian 

 tooth. First peduncular segment of antenna armed with a slender 

 spine nearly as advanced as the middle spines of the front. 



Legs slender. The propodus of the first leg reaches end of merus 

 of second, the merus of second leg reaches a little past the middle 

 of the propodus of the third. Second leg about three times as long 

 as width of carapace. Merus joints of first three legs similar to 

 those of gracilis. Last leg less slender than in gracilis; a small 

 tooth on the coxa is visible in dorsal view in line with the row of 

 tubercles above posterior margin of carapace (see fig. 3, pi. 41). 



Measurevients. — Female holotype, length of carapace 5.2, width 

 of same G.G mm. 



Range. — Known only from the type-specimen. 



Afinities. — In C. cursor and C. gracilis, the teeth and tubercles 

 of the carapace are all blunter and rounder and the inner suborbital 

 tooth is more advanced; in C. gracilis there is only one lateral tooth 

 and the legs are longer.
