Cohere tetrica, G. S. Brady. 



Cythere tetrica, G. S. Brady, 1880, Bep. Chall., Zool., pt. iii, 

 p. 104, pi. xxiii, figs. 5 a-d. 



This somewhat striking form has been previously recorded 

 only from Booby Island, Torres Strait, 6 to 8 fathoms. 

 One right valve found in our series. 



Cythere dictyon, G. S. Brady. 



Cythere dictyon, G. S. Brady, 1880, Bep. Chall., Zool., pt. iii, 

 p. 99, pi. xxiv, figs. 1 a-y. 



Five separate valves of this widely distributed species were 

 found, one of which appears to belong to a full-grown female, 

 and shows the posterior spines arranged along the border of 

 the shell. Another example is a small valve of the same 

 sex, whilst the remainder are valves of male specimens. 



Cythere prava, Baird sp.

C. prava is a South Pacific form, but not exclusively so. 

 It appears to be more at home in shallow water. Our 

 specimen is a right valve, the surface of which is more than 

 usually coarsely sculptured. 



Cythere dasyderma, G. S. Brady. 

 Cythere dasyderma, G. S. Brady, 1880, Rep. Chall., Zool., 

 pt. iii. p. 105, pi. xvii, figs. 4 a-f; pi. xviii, figs. 4 a-f. 



In the "Challenger" dredgings this species was charac- 

 terized as a deep-water form, so that its occurrence in the 

 present sounding is somewhat exceptional. It is also widely 

 distributed. 



One right valve. 



Genus Krithe, Brady, Crosskey and Robertson. 



Krithe producta, G. S. Brady. 



Krithe producta, G. S. Brady 1880, Rep. Chall., Zool., pt. iii,

 Soc. Lond. (Zool.), vol. xxviii, p. 427. 



This very variable form occurs oftenest in deep water. 

 The deepest sounding from which Dr. Brady obtained his 

 specimens was taken at 1,675 fathoms. The writer records
