703 Brady and Norman — Monograph of the 3Iarme and Freshwater Ostracoda ■ 



Sub-fam. — Halocyprinae. 



Shell short, ventricose, scarcely longer than high ; rostral process short, sinus 

 obsolete, presenting only a slight sinuation of the valve. Frontal tentacles alike 

 in both sexes ; capitulum club-shaped, bent at an obtuse angle on the peduncle. 

 Peduncle of the antennule angularly bent, setae flexuous ; in both sexes one long 

 terminal seta, and four short equal sensory ones. Secondar}^ branch of antenna 

 without mamilliform prominences ; setae of the swimming branch plumose, and 

 nearly twice as long as the peduncle. Basal joint of the mandible-palp short, 

 not longer than the second joint, its biting-plate produced, and " shovelshaped." 

 First and second pairs of maxillaj short, and nearly equal. In the male the first 

 maxilla is like that of the female both in size and shape, and the terminal setae do 

 not form an elongated lash. 



Genus 1. Halocypris, Dana {ex parte). 



Rostral process short, right valve prominent in front ; rostral sinus inconspi- 

 cuous; ventral margin strongly convex; a hinge-joint, consisting of a tooth on 

 the left and socket on the right valve at the anterior extremity ; hinge of hinder 

 end scarcely developed. Free edge of the valves strongly rounded and thickly 

 beset with gland-cells. Principal seta of the secondary branch of the antenna 

 dilated and lancet-shaped at the end. Mandible without a crenulated pad and 

 accessory teeth, but having a broad conical process directed towards the apex 

 of the limb.
