Station 87 (North of New Zealand). Thirty metres. 



A single young male measuring '88 mm. to the end of the posterior .spine. 



The shell closely resembles Dr. Fowler's figure of Stage III (I.e., pi. XVII, fig. 56). 

 The mouth of the right asymmetrical gland is slightly prominent, and the other three 

 pairs of glands conspicuous. First antennae of female type.

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-veutral 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 postero-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 leno-th. 



Frontal organ slender, unjointed. 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.
