PLATE IY. 
1. Lacocnitus Cuittoni, n.sp. Pl. IV, Fig. 1. 
Shell very small, turbinate, subperforate, rufous, slightly glossy, 
thin, semi-transparent, with rather close longitudinal membranous 
white costelle, which easily rub off; they are nearly equidistant, five 
to six per millimetre. Spire conical, apex rather pointed; periphery 
rounded; whorls 5, convex, the first three increasing slowly, the 
others more rapidly, faintly microscopically spirally striated, the body- 
whorl about two-thirds of the total height; suture impressed. 
Aperture subcircular, slightly oblique; peristome simple, straight; 
notch at the suture very slightly indicated; columella lip somewhat 
callous, expanded, completely covering the small umbilicus ; margins 
convergent, not united by a callus. Base rounded. Operculum not 
seen. Alt. 3, diam. 2°25 mm. 
Type in my collection. 
Hab.—Fern Flat, Buller River, South Island. A single specimen 
found under a log by Dr. Ch. Chilton, whose name I have much 
pleasure in connecting with this species. 
L. Chiltoni is near to L. Hedleyi, Sut., but the latter is more 
depressed, the membranous plaits are not,equidistant on the body- 
whorl, the margins of the aperture approximate more, and the narrow 
umbilicus is open. ’ 
2. Lacocuiius (?) Sruperr, n.sp. Pl. IV, Fig. 2. 
Shell very small, globosely conoidal, perforate, whitish-horny, 
| faintly glossy, fragile, transparent, smooth, showing under the lens 
_ Tegular and close lines of growth. Spire conoidal, rather short ; 
: whorls 34, rather rapidly increasing, convex, slightly flattened below 
the suture ; periphery rounded; suture deep. Protoconch smooth, 
Tather obtuse. Aperture ovate, longitudinal; peristome simple, 
acute, outer lip regularly arched, basal lip strongly convex, 
- columella lip almost straight, vertical; margins converging, not con- 
— tected by any callosity. There is no indication of a notch at the 
| suture. Umbilicus pervious, very narrow. Base convex. Operculum 
| ey transparent, with few whorls round a subcentral nucleus. 
diam. 2°25mm.; height of aperture 1°5 mm. 
| Ype n my collection. 
ab —W hangarei, North Island (Mr. Grosch).
