'»****'■ M*- Station 282 (Antarctic). 0-1,000 metres. Two males (one young), two females 
(one young). 
Shell of female. Height rather more than half the length. The greatest height 
a little behind the middle. Ventral margin scarcely arcuate, passing in a broad even 
curve to the posterior margin, which is broadly arched, and meets the straight dorsal 
margin in a rounded obtuse angle. The antero-ventral curve viewed from the inside 
has an imbricate appearance. Glands : Right asymmetrical gland opens at about half 
the height of the shell. Left asymmetrical gland at the nastero-dorsal angle. The 
posterior margin of the left valve bears a row of glandular cells. The remarkable 
group of gland-cells in the centre of the ventral margin of each valve, though present, is 
less noticeable than in the male. 
First antenna bears four sense-tubes of unusual length. 
Frontal organ slender, unjoin ted. Head almost straight, hairy except at the tip, 
which is rounded, scarcely wider than the stem. 
Second antenna. One bristle of the secondary branch is longer than the other 
four, sword-shaped, broadening towards the tip, acutely pointed.
