36 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY. 
Hab.—Whangarei, North Island (Mr. Grosch). 
L. elegans is very distinct from all the species of the genus hitherto 
described ; the aspect of the base and character of the lamellx cal] to 
mind some of the species of Sagda. 
7. Laoma (PurixeNnataus) Lucrpa, n.sp. Pl. IV, Figs. 13-15. 
Shell very small, depressly-turbinate, subperforate, yellowish- 
‘horny, shining, pellucid, thin, somewhat smooth, with fine lines of 
growth (more distinct at the suture), microscopically finely decussate, 
Spire conoidal; periphery rounded; whorls 34, gradually increasing, 
rounded; suture rather deep. Protoconch smooth. Aperture lunate, 
transverse ; peristome straight, acute, somewhat callous, columella 
lip subvertical, slightly reflexed. Umbilicus very narrow, partly 
covered by the columella lip. Base rounded. Diam. maj. 3, min, 2°75 
alt. 2mm. | 
Type in my collection. 
Hab.—Near Auckland, exact locality not stated (Mr. Wright). 
This species comes nearest to L. transitans, Suter, which, however, 
is higher, banded with chestnut, and has the periphery keeled. 
The jaw and radula are typical, the former being strongly papillate. 
The formula of the radula is 20—1-20. 
var. ELEVATA, n.var.— This variety is higher; the number of 
whorls is the same, but they are narrower, especially the fourth and 
fitth. The protoconch is also smooth, and the shell microscopically 
finely decussate. The colour is darker, the periphery keeled, and the 
mouth destitute of callosity. Diam. maj. 3, min. 2°75; alt. 2°5 mm. 
Type in my collection. 
Hab.— Whangarei, North Island (Mr. Grosch). 
8. Laoma (Purrxenaruus) sprratis, n.sp. Pl. IV, Figs. 16-18. 
Shell very small, depressly-turbinate, perforate, pale-horny with 
somewhat irregular radiate rufous streaks, dull, thin, semi-transparent, 
with close-set longitudinal membranous costelle, produced into ragged 
processes at the periphery ; there are five to six costelle per millimetre ; 
the interstices decussate. Spire conoidal, apex pointed, periphery 
sharply keeled; whorls 5, gradually increasing, flatly rounded ; suture 
impressed, somewhat constricted, between the fourth and fifth whorls. 
Lhe protoconch is smooth, but the rest of the shell is distinctly 
spirally striated, most conspicuously so on the base. Aperture trans- 
verse, squarish; peristome straight, acute, outer lip sharply keeled, 
basal lip regularly broadly arched, columella lip subvertical, slightly 
arched, and reflexed. Umbilicus nalrow, pervious, deep. Base rounded. 
Diam. maj. 3:25, min. 2°75; alt. 2mm. 
Type in my collection. 
Hab.—Pclorus Sound, Marlborough, South Island (Mr. J. McMahon). 
L. spiralis stands nearest to J. phrynia, Hutton, but differs from it 

in having a more acute spire and a sharper keel on the periphery, 0 | 
its less rounded whorls with their very distinct spiral striation, 10 
Possessing ragged processes to the costelle, and a much narrower 
umbilicus as well as a constricted portion of the suture.
