COCCULINA coERcrrA, sp. iiov. 

 (Plate liv., figs. 1, 2). 

 Shell small, thin, almost symmetrical, slightly elevated, very 

 narrow. Colour white. Apex prominent, smooth, inrolled, two- 

 whorled, situated a little behind the centre of the shell. 

 Anterior and posterior slope about equal. Sculpture, slight concen- 

 tiic growth lines. Edge of aperture sharp, smooth ; sides straight ; 

 ends rounded. Length, 4-6 ; breadth, 1-3; height, l-15mm. 



The present collection contained a single specimen, another was 

 dredged by Mr. W. F. Petterd and myself in 300 fathoms twenty- 

 seven-and-a-half miles east of Sydney.

This species was originally described from Foveaux Strait, New 

 Zealand. Its range is now extended to Australia. The example 

 dredged by the "Miner" is larger than the type, being 1-5 in 

 height, 2-5 in length, and 0-9 mm. in breadth. The surface is 

 clothed with a rather caducous ochraceous epidermis disposed in 

 oblong grains. When stripped of the epidermis the white surface 

 of the shell shows no trace of these grains, and would readily pass 

 for a different species. Towards the margin some specimens have 

 broad shallow radial undulations. A specimen from off Port 

 Stephens is in this Museum ; the " Thetis " took it in 63-75 

 f.'ithoms off" Port Kembla, and I have dredged it in 20 fathoms in 

 Wreck Bay, N. S. Wales.
