RECORDS OF THE AUSTRALIAN MUSEUM, 



8CALA TURRISPIIARI, Sp. ttOV, 



(Fig. IS). 



Shell minute, solid, very tall and slender, conspicuously tabu- 

 late. Colour, pale cream. Whorls eight and a half (including 

 two and a half whorled protoconch), deeply con- 

 stricted at the suture, flattened medially, and 

 angled above and below. Sculpture, the proto- 

 conch smooth and glossy, extreme apex asym- 

 metrically protuberant, remainder with two spiral 

 keels, and a third margining the suture. After 

 the protoconch the adult sculpture commences 

 suddenly without transition. The adult whorls 

 are obliquely crossed by about seventeen blunt, 

 close set, widely and squarely projecting lamella, 

 which disappear on the base. Both lamellse and 

 interstices are crossed by fine, dense, spiral grooves 

 which fret the lamellti? blades. Aperture I'ound. 

 Length, 2-64 mm.; breadth, 0-8 mm. 



The four specimens before me are not suffi 

 ciently perfect to furnish full details of length, 

 number of whorls, apertui'e, and base. The 

 turrited spire, peculiar ribbing, and small size 

 of the novelty, amply distinguish it from any 

 Austra'ian species.

This species has not hitherto been traced so 

 far noi'th. It appears to me to be i-elated 

 rather to the Eissoidse than to the Scalida?. ^'^0ff
