MOLLI'SCA, T. SMITH. 7.1 



The soft parts accompany the shell, and since they present nu opcrciilinn. and 

 taking into consideration also the general form of the shell. I am inclined, until the 

 animal lias been investigated, to place this species in the genus Volutharpa.

Station 331 : 250 fathoms. 



A single specimen was found by .Mr. R. E. Priestley, at " Kvans Cove. Terra 

 Nova Bay, Victoria Land, in "lacier 30 feet above sea level." Possibly carried to 

 this place by a bird, or, being verv light when devoid of the animal. Mown there 

 by the high winds which prevail in that inclement region.

Station 194: 180-200 fathoms. 



A single specimen from this station containing the animal is rather larger than 

 the type, and some of the lamella; on the liack of the body-whorl are produced 

 into hook-like hollow spines. 



It is ID'5 mm. in length, 10 in diameter, and consists of six volutions.

This species is (juite distinct from T. coulmanensis, differing in having the wlmrls 

 at the shoulder just below the suture rounded, and not tabulated or angulated. In 

 character the erect lamellae are very similar to those of Trophon laciniatus (Martyn).

 volutions in these specimens are less sloping than as represented by Thiele's tigure. and 

 the columella is not so straight, inclining to the left anteriorly.
