divisions; these bands are always distinct without any 

 shading or accessory bands or Hnes ; there is also a patch 

 of the same colour surrounding the anterior plaits. 



Length, 13 m.m. ; breadth, 5.5 m.m. 



Locality: Type from 100 fathoms seven miles east of 

 Cape Pillar, with a number of others; also from 80 

 fathoms 10 miles east of Schouten Island. 



This might be described as a giant M. mustellina, 

 Angas. It is distinguished from that species by its great 

 size and solidity, and the different colour pattern, which 

 is very constant. 



It is a very fine and conspicuous form, which I have 

 much pleasure in dedicating to mv friend, Mr. Charles 

 Hedlev. 



MARGINELLA ALBOMACULATA, N.SP. (PL. 

 XIII., FIG. 2.) 



Shell bulbiform, or drop shaped, very solid, glossy; 

 spire quite hidden, the summit of the shell being very 

 broad and dome shaped; aperture as long as the shelly 

 rather narrow, and much curved; outer lips massive, but 

 with a sharp edge; it bends widely out above, but with 

 an inward sweep below, giving it a sinuous outline; it 

 descends in front below the pillar, in joining which it 

 bends far back; well within the lip are numerous obscure 

 rib-like plications; columella very convex, heavily enam-* 

 elled, and spreading well out over the base of the shelly 

 and bearing six plications, of which the first two are much 

 the largest, the second being the largest of all, and reach- 

 ing w^ell out over the ventral base; the upper four are 

 much further within the aperture, and become smaller, 

 the last being little more than a small tubercle; colour 

 greyish-white, with about seven revolving lines of obscure 

 elongated white spots. 



Length, 6 m.m.; breadth, 4 m.m. 



Localitv : Type from Frederick Henry Bay in a kelp 

 root, with one other specimen. 



This is very distinct from any other Tasmanian 

 species, and seems to belong to the saggitata group.
