Eight specimens, the largest 2mm. long, were caught in the web of a worm tube 
taken January 19th, 1912, at Aerial Cove, Macquarie Island, by Mr. H. Hamilton. 
These correspond well to Dr. Lamy’s figure of a species from Graham’s Land on 
the opposite coast of Antarctica. 
Two generic names have already been applied to this species. Reasons for discarding 
both and adopting Bochefortia are related by Dr. W. H. Dali, Trans. Wagn. Inst., iii., 
1900, p. 1158. 
Rochefortia macquariensis sp. nov. 
(Plate IV., figs. 40, 41.) 
Shell small, thin, rather inflated, inequilateral, the ventral and posterior margins 
rounded, the anterior more pointed. Colour white under a thin cream-coloured 
epidermis. Surface with a nacreous lustre, sculptured by very fine and close concentric 
threads. Length, 3-3 ; height, 2-7mm. 
Three specimens from a worm tube collected January 19th, 1912, at Aerial Cove, 
Macquarie Island, by Mr. H. Hamilton. 
This seems related to Tellimya ovalis Thiele, from the Davis Sea, but has a more 
prominent umbo and the anterior side more sharply produced.

In 1898 Mr. Smith was inclined to reduce this form to a variety of L. miliaris Philippi, 
but Dr. Thiele has since refigured both to show the distinction in contour between them. 
As Mr. Smith wrote, “ the dentition is a little different also,” I have here figured the
