diameter apart, cross the shell obliquely. A few faint and distant 

 spiral grooves are perceptible. Traces are present of a thin, 

 membranous yellow epidermis. Aperture auriculate, slightly 

 oblique. Outer lip sinuous, neither thickened nor reflected, 

 columella broadened at the base and a little reflected. A small 

 but sharp and deeply seated plication occurs on the body whorl, 

 anterior to the centre; immediately in front of this, and deeper 

 still, is a second, ill-developed fold. A heavy callus is spread on 

 the body whorl. Length 3 mm.; breadth 1-16 mm. 



Hab. — The material at my disposal was collected in the neigh- 

 bourhood of Sydney by Mr. J. Brazier as follows :— (1) East side 

 of Double Bay; one specimen; type : (2) Under a small stone on 

 a " samphire flat " at the head of Tambourine Bay, in company 

 with Ophicardelus ; three living specimens : (3) In shell sand, 

 Cook's Landing Place, Botany Bay; two dead shells. 



Type to be preserved in the Australian Museum. 



The species before us is the second of the genus Leuconopsis, 

 founded by Hutton (Trans. N. Z. Inst., xvi., 1883 [1884], p. 213) 

 for the reception of Leuconia obsoleta, Hutton, (Journ. de Conch, 

 xxvi, 1878, p. 43, and Man. N.Z. Moll, p. 34). The name implies 

 affinity to Leuconia, but to my mind the genus nearest approaches 

 A icriculus. 



Capt. Hutton, whose kindness to his fellow naturalists is un- 

 failing, has sent me, for comparison with L. inermis, a set of 

 co-types of L. obsoleta from Auckland, New Zealand. One of 

 these, whose length is 2-24 and breadth L44 mm., is figured (fig. 16) 

 for comparison with the novelty. The Australian species differs 

 by its feeble columellar plait, more whorls, absolutely larger size, 

 but relatively more slender proportions.
