 Family CYPRIDIDiE. 



SubfaiTiily HERFETOC^FRIDIN".^:. 



Genus HERPETOCYPRIS Brady and Norman, 1889. 



HERPETOCYPRIS TESTUDINARIA, new species. 



Plate LVIII, figs. 1-10. 



Length 2.10 mm.; height 1 mm.; breadth 0.80 mm. 



Shell nearly twice as long as high, the greatest height behind the 

 middle, the width somewhat less than the height (Plate LVIII, figs. 

 1 and 2). Surface of the shell with short scattered hairs (Plate 

 LVIII, fig. 3), the anterior border minutely crenulated and thickly 

 set with slender hairs. The lucid spots are eight in number, mostly 

 very much longer than wide (Plate LVIII, fig. 4). 



The antennula (Plate LVIII, fig. 5) has a single short spine on the 

 second joint, two on the third joint, and on the fourth two long and 

 two short seta3. The last three joints have each three long setae. 



The antenna (Plate LVIII, fig. 6) has the group of swimming setae 

 of the second joint shortened as is usual in this genus. The third joint 

 has two setae at the middle of the outer border and four on the op- 

 posite border. The arrangement of the other setae is shown in the 

 figure. 



The first foot (Plate LVIII, fig. 7) has a single spine on each of 

 the three joints above the last, that one having two spines and the 

 long claw characteristic of this appendage. 



The second foot (Plate LVIII, fig. 8) has a short last joint with a 

 beak-shaped short claw and a single spine. The penultimate joint 

 has a single spine at the middle. The antepenultimate joint has a 

 single spine near the distal end and the basal joint has two spines at 

 its distal end. The abdominal furca (Plate LVIII, fig. 9) is smooth 

 throughout. At the base of the proximal one of the two claws is a 

 short spine (Plate LVIII, fig. 10). 



Specimens of this species were collected in May, 1906, by Mr. 

 Bryant at Funk Island, Newfoundland.
