To Ericusa are assigned : fulgetrum Sowerby, papillosa Swain- 

 son, and sowerhyi Kiener.

Alcitho'e H. & A. Adams, Gen. Rec. Moll., i., 1853, p. 164, type 

 pacijica (arabica) selected by Fischer, Manuel, 1883, p.607. 



This genus, which is nearly related to Adelomelon, does not 

 seem to occur on the Australian coast. Solander erroneously 

 recorded V.pacifica from the Endeavour Reef. The same species, 

 under the name of V. rossiteri, was described by Brazier* from 

 Gippsland. Reeve, by mistake, recorded A. gracilis Swainson, 

 from Australia. Species from the Australian Tertiary, which 

 have been attributed to the genus, do not seem to be happily 

 placed. 



Marginella malina, sp.nov. 

 (Plate Ixxxii., fig. 65.) 



Shell small, rather thin, smooth and glossy, subtriangular in 

 outline, shoulder rounded, apex slightly projecting from a rather 

 flat summit. Colour uniform white. Whorls three, wound 

 nearly in the same plane. Aperture straight, wide, as long as 

 the shell. Outer lip rather broadly expanded. Plications four, 

 narrow, erect, becoming smaller and deeper posteriorly, the last 

 midway along the mouth. A slight glaze on the inner lip. 

 Canal a little produced. Length, 3; breadth, 2*4 mm. 



Hab. — I dredged several specimens in 100 fathoms, off WoUon- 

 gong, and, again, in 80 fathoms, off Narrabeen, N.S. W. (type). 



The latter were erroneously catalogued as M. brazieri Smith. f 

 That species is a larger shell, with more exsert spire, and lives 

 in deeper water. 



Marginella translucida Sowerby. 



(Plate Ixxxii., tig.67.) 



This species was discussed in the last part of these Studies 



(xxxviii., p. 302). A figure of a specimen 5-5 mm. long, from 



Sydney, compared with the type in the British Museum, is here 



presented.
