middle: seen from above elongate-ovate (fig. 17), more than twice as long as broad, 

 lateral margins evenly arcuate, tapering to the extremities, of which the anterior is sub- 

 acuminate, the posterior narrowly ruuiidcd. Surfece of the sliell smooth, pubescent, 

 with very fine and rather closely-set short hairs (fig. 19); colour light green. The 

 ventral margin of the left valve is produced in the centre so as to form an overlapping 

 flange, which is marked by fine transverse striae (fig. 18). Length -87 mm. Swimming- 

 setae of the antenncE (fig. G) reaching somewhat beyond the apices of the claws ; terminal 

 joint of the antennae narrow, about one-third as long as the preceding joint ; secrmd 

 pair of maxilla; (maxillipeds) in the female (fig. 22) digitiform, with a terminal brush of 

 rather long setae, and bearing an elongated palp which ends in one short and two very long 

 setae ; in the male the limb is strongly prehensile, on the right side (fig. 24) thick, with 

 angulated margins, and bearing a very broad, blunt, almost falcate terminal claw, on 

 the left side (fig. 23) the limb is much narrower, is not marginally angulated, but has 

 on the inner side a tuft of four or five small hairs and terminates in a sharply bent, 

 hook-like claw ; terminal unguis of the first pair of feet (tig. 25) stout and strongly 

 curved ; the second foot bears terminally two slender curved claws, one of which is very 

 short, and a long seta; postabdominal rami (fig. 27) simple, cylindrical, each of them 

 bearing a long terminal seta and another very minute seta placed a little on the 

 proximal side of the apex. Copulative organs (fig. 28) elongated, very complex, 

 ending in a somewhat hatchet-shaped intromittent process ("?): on each side of the 

 postabdominal rami in the female is situated an irregularly shaped laminar process 

 — spermatheca ] (fi.g. 29) ; the testes form two large ovoid coils of delicate spermatic 

 tubes. 



Hab. A gathering from Puerto de St. Maria, near Cadiz, contains numerous examples 

 of this species. 



The genus Cypridopsis proper is distinguished from the subgenus Candonella chiefly 

 by a much greater tumidity of shell and by the armature and relative lengths of the 

 last two joints of the antenna — the penultimate joint in Cypridopsis being prolonged as 

 far, or nearly as far, as the extremity of the last joint, and the claws being slightly 

 different in the two sexes. Except as a matter of convenience, the differences seem to 

 me scarcely sufficient to warrant the separation of Candonella as a subgenus. 



Genus Ctpeetta Vavra'. 



Shell as in Cypridopsis. Second pair of legs forcipate. Postabdominal rami as in 

 Cypris, but much smaller and more slender. 

 The name Cypretta has been applied by Vavra to this group as a subgenus of 



' Vavra, " SlissTvasser-Ostracoden Zanzibar's" (Jahrbuch der Hamburgischen wissenschaftliclien Anstalten 

 xii. 1895).
