Specific Characters. Female. Shell rather tumid, seen laterally, of a 

 somewhat irregular rounded oval shape, greatest height in the middle and not 

 fully attaining 3 /4 of the length, dorsal margin almost straight in the middle, 

 sloping gently in front, more steeply behind, ventral margin evenly curved, 

 posterior extremity broader than the anterior and obliquely blunted, forming 

 below a slightly produced angular corner; seen dorsally or ventrally, rather 

 regularly ovate, with the greatest width about in the middle and somewhat 

 exceeding half the length. Frontal incisure of valves moderately deep and 

 turned upwards, being overhung by the rather prominent rostral part, which 

 is obliquelly truncated at the end, with the upper angle rather slight, the 

 lower produced in a small procurved dentiform point. Valves of rather firm 

 consistency and only slightly transparent, surface evenly vaulted and minutely 

 punctate, being everywhere clothed with short stiff hairs; rostral prominences 

 fringed both in front and below by a hyaline finely ciliated border, selvage below 

 the incisure short and rounded off. Eyes scarcely visible in the living animal, 

 being in most cases quite devoid of pigment. Inner ramus of posterior 

 antennas very small, with the distal joint somewhat compressed and provided 

 in front with a slender ciliated seta, carrying moreover at the tip a peculiarly 

 tortouos thin bristle abruptly bent at the base; outer ramus very flexible and 

 having almost constantly the outer part of the natatory setae brocken off. 

 Last pair of limbs with a rather great number of cleaning spines, amounting 

 to 28 on each limb. Caudal rami each with 10 marginal claws. 



Male very unlike the female in its outward appearance, the shell being 

 of a much more elongate, oblong oval shape, with the dorsal and ventral 

 margins only slightly arched. Frontal incisure of valves much wider than in 

 female, almost rectangular, and the rostral prominence far less procumbent, 

 whit the tip obtusely blunted and not exhibiting any trace of an angle below. 

 Eyes largely developed and very conspicuous in the living animal. Anterior 

 antennae with the 2 prolonged apical setae exceeding the stem of the antennae 

 by about half their length. Posterior antennae with the outer ramus much
