REPORT ON THE GASTEROPODA. 525 



jects a thickish stalked mushroom-like foot, out of the centre of which extends a long thin tongue- 

 like process, somewhat like that figured by Gould in the " U.S. Exploring Expedition," pi. xiv. 

 fig. 247, but shorter and not subulate. 



In regard to the shell, it is of course hardly necessary to say that the apical " nucleus " is not 

 " sinistral " (Adams, Genera, vol. i. p. 239). 



Stilifcr ebiirrieios, Desh. (Conch, de Bourbon, p. 57, pi. vii. fig. 25) is larger than this species, with 

 a shorter spire, fewer whorls, and a more marked style. 



2. Stilifer crotaphis, 1 n. sp. (PI. XXXVII. fig. 10). 



Station 162. April 2, 1874. Lat. 39° 10' 30" S., long. 146° 37' E. Off East 

 Moncoeur Island, Bass Strait. 38 fathoms. Sand and shells. 



Shell. — In form like a Eulima, high and conical, milky hyaline and glossy, with 

 faint spirals and lines of growth, convex whorls, and a fine subulate slightly bent apex. 

 Sculpture: Longitudinals — there are many fine but not sharp scratches in the lines of 

 Growth. Spirals — there are feeble obsolete ridges and furrows, and a very faint angula- 

 tion at the periphery, which occurs just at the edge of the base. Colour pure white and 

 hyaline, but slightly milky. Apex very small and sharp, but without any definite style. 

 Spire high and narrow, conical, with slightly concave profile lines ; it is bent at the very 

 tip. Whorls 10, small, being both short and narrow, of very regular and slow increase, 

 slightly convex ; the base is short and rounded. Suture strong, being linearly impressed 

 and slightly marginated below. Mouth somewhat quadrangular, being pointed above and 

 in front of the pillar. Outer lip sharp and thin, scarcely convex till it reaches the outer 

 corner, where it is slightly angulated and then is curved across the base. Inner lip : there 

 is no trace of it across the body ; the junction of the body and pillar is very obtuse- 

 angled. The pillar is very straight, with a slightly thickened and rounded edge ; the 

 junction of the pillar and outer lip is angulated. H. - 145 in. B. 0"089. Mouth, height 

 0-086, breadth 0"055. 



The outer lip of the solitary specimen of this species is somewhat broken, especially toward the 

 point of the pillar, which is thus left abnormally projecting as in Stiliferina. The shell is much 

 smaller, narrower, more conical and sharper pointed than Ajoicalia giintheri, Angas, from New South 

 Wales ; than Stilifcr brazieri, Angas, from Port Jackson, it is much more compressed and acute.
