moist atmosphere of ship-board. 



The type appears to have been 

 described from an abnormally thin 

 and varicose shell, which also, judg- 

 ing from the slight development of 

 the digitate processes of the outer 

 margin of the aperture, was probably 

 young. The thinness of the type 

 sj^ecimen is perhaps to be explained 

 by its having come from a greater 

 dej'tth, our present series sli(»vvlng 

 tliat the thickness of the shell varies 

 inversely as the depth. 



Family Phoridae. 



4. Xenopliova iiallidala (Reeve). 



A tolerably perfect dead shell was taken off the west coast 

 of the Andamans in 240 to 220 fathoms (Station 53). It 

 may be mentioned that Prof. Wood-Mason dredged a dead 

 and weathered specimen of this shell in the Andaman Sea at 

 228 fathoms, at the same time with tiie type of the Ilomarid 

 ^^x\Vi?> Nephropsis \ and that in 18S7 Commander Carpenter 

 dredged a fine series of living specimens in 290 to 240 fathoms 

 veiy near the position of Station 56. 



Family Capulidse. 



5. Amalthea^ sp. 



Some small specimens, symbiotic with Rostellaria deli- 

 catula, were taken in 98-102 fathoms (Station 96). 



Family Calyptrseidse. 

 6. Crepidula^ sp. 



At Station 105 in the Laccadive Sea, at 740 fatlioms, a 

 single specimen was obtained of a curious form which we 

 doubtfully refer to this genus. 



The shell is broadly and not quite regularly oval, depressed, 

 thin, translucent, and covered with a delicate olive-green
