Shell elongated, twice as long as high, each valve with a short, strong, spinous 

 prominence at the postero- dorsal angle ; rostral process short and broad. Length 

 of the shell, l'5-l-8 mm. ; height, 0'8— 0*9 mm. Capitulum of the frontal tentacle 

 in the female (as well as in tlie male) clubbed, angularly bent, and beset with 

 numerous small spines. Terminal seta of the antennule in the male bearing abou< 

 thirty pairs of closely set barbed hooks. Proximal sensory filament thrice as long 

 as the distal one. Principal seta of the secondary branch of the natatory antenna, 

 in the female, long and powerful, more than one-third longer than the longest of 

 the sensory setfe. In the male the three sensory setae are very slender; the 

 hooked process is bent into an irregular curve, and on the left side is very 

 strongly developed ; one of the two lateral setse much elongated. 



Found at a depth of 1500 metres in lat. 37° 45' N. ; long. 13° 38' W. ; also in

Shell rather short ; height equal to about three-fifths of the length, nearly 

 quadrangular, extremely thin and pellucid, much compressed laterally ; rostrum 

 large and curved. Length, 1*5 mm. ; height, 0-9 mm. 



Frontal tentacle of the female slender, elongated, with very long, angularly 

 bent extremity, which bears on the upper margin a few spine-like hairs, and on 

 the under side two rows of the same. Capitulum of the tentacle in the male 

 shorter, broadly club-shaped, irregularly armed with spinous hairs. Terminal 

 seta of the male antennule bearing about twenty pairs of slender, thickly-set 

 spines, and not longer than the two neighbouring setae ; proximal sensory seta
