has correctly stated that this name is an absolute synonym of 

 suturalis Lamarck, Suter noticed that it was preoccupied by 

 Forbes, and has proposed a substitute. 



It is improbable that A. intermedia was taken, as alleged, at 

 Sydney. And Angas went astray in substituting that name in 

 liis catalogues for his previous N. suturalis var. Since this form 

 is still undistinguished by a name, it is now proposed to call it 

 A. particeps. From Sydney, it appears to range east to the 

 Kermadecs and Cuvier Island in New Zealand, south to Port 

 Phillip, Victoria, and west to Port Lincoln, South Australia. 

 Both A. glans and A. suturalis occur in Queensland; I took the 

 first at the Palm Islands, and the second at Mapoon. 



Arcularia pilata, sp.nov. 

 (Plate Ixxxiv., fig.80.) 



Shell small, narrowly ovate, rather solid. Colour pale buff, 

 with occasionally a narrow spiral orange line, chocolate at the 

 insertion of the lip and the tip of the canal. Whorls six, the 

 first two and a half composing the protoconch, the rest constricted 

 at the suture. Sculpture : radial ribs, about fourteen to the 

 whorl, run from base to suture, over-riding both ribs and inter- 

 stices are polished cords, ten on the last whorl, and five on the 

 penultimate; in the meshes formed by the intersection of ribs 

 and cords are fine, crowded, spiral hair-lines, as if neatl}^ brushed. 

 Canal short, a little recurved. Aperture slightly ascending, 

 varix broad and projecting, outer lip with six interior denticles. 

 Length, 5*7; breadth, 3 mm. 



Hah. — Several specimens, Torres Straits, 12 fathoms; another, 

 Darnley Island, 30 fathoms, J. Brazier. 



A. compacta Angas, has a general resemblance to the novelty, 

 but is half as long again, has a more prominent sculpture, and 

 lacks the tine hair-lines of the secondary sculpture of A. pilata. 



Pyrene felina, sp.nov. 



(Plate Ixxxiv., figs.82, 83.) 



Shell rather thin and light, ovate-acuminate, flattened at the 



periphery, contracted at the base, spire pointed, later whorls 



becoming turreted. Whorls eight, the first two smooth, forming
