The carapaces found in the present dredgings are of typical 

 dimensions. The depth is rather exceptional, 390 fathoms 

 being the deepest hitherto recorded for this species. 



Station 36, east of Tasmania, 777 fathoms. Frequent. 



MACROCYPRIS GRACILIS, sp. nov. 

 (Plate ii., figs. 2a-c.) 



Description. Carapace very slender ; siliquose ; highest 

 in the middle. Height less than one-fourth the length. 

 Dorsal margin evenly arcuate, ventral margin concave just 

 above the middle and curving out to meet the depressed 

 anterior margin. Posterior end tapering to a blunt point. 

 Edge view, elongate-ovate, compressed at the extremities. 

 Length, 1mm. ; greatest height, .23mm. 



Relationships. This species bears a general resemblance to 

 M. tenuicauda, Brady 1 but is much more elongate, and the 

 dorsal border more evenly rounded. The specimen figured by 

 Dr. Egger from Station 90, off Western Australia, at 357 

 metres 2 and referred to M. tenuicauda, Brady, is probably 

 referable to this new species. 



Station 36, east of Tasmania, 777 fathoms. A left valve.

Separate valves of the above species occur in the under- 

 mentioned dredging. They agree in outline with Brady's
