figs. 2a, ^ 2d. 
Localities. —Awamoa (type); Pukeuri; Rifle Butts; Ardgowan ; 
Pareora; uppermost Mount Brown beds, Weka Pass, large specimen 
[= N. australis (in part) of Suter, 1921, р. 43]; ? Waikaia (umbilicus is 
concealed by matrix); ? McC ullough's Bridge, Waihao. 
ne good specimen from the last locality has outer lip strongly retracted 
to suture and funicle smaller and more separated from umbilical walls. 
Two smaller imperfect specimens are not so distinct from notocenica, 
consequently more specimens are needed before a separation would be 
justified. 
Natica inexpectata Finlay. (Plate 55, fig. 13.) 
1924. Natica inexpectata Finlay, Trans. N.Z. Inst., vol. 55, p. 452. 
Type in Scd collection of Mr. H. J. Finlay. 
Height, 1 ; diameter, 15 mm. 
Locality. келү A. Clifden, Southland. 
Distinguished from N. zelandica by its different sei more convex 
and wider whorls, and smaller umbilical funicle. N. co and N. sub- 
lata are only about half the size, and have much gies ee 
Natica bacca n. sp. (Plate 55, fig. 14.) 
Shell small, oval; spire low, suture tangential; aperture large, semi- 
lunar; outer lip gently retracted to suture for considerable distance ; inner 
thin callus on parietal wall and somewhat narrow but arge 
funicle which about half fills umbilicus; notch separating funicle from 
parietal callus very shallow. 
Type in collection of New Zealand Geological Survey. Kindly pre 
sented by Dr. P. Marsha 
Height, 5mm.; length, 5 mm. 
Locality.—Hampde 
species is probably the N. zelandica of former lists. The very 
shallow notch between the parietal callus and the funicle, and also the 
narrowness of the latter, distinguish the species from N. notocenica, which 
it resembles in shape. 
Natica planisuturalis n. sp. (Plate 55, figs. 10, 11.) 
Shell small, broadly ovate; spire moderately raised, less than half 
the height of aperture; who rls 5, flattened above; suture tangential ; 
outer lip Maur concave, orit at about 30° from the vertical, slightly 
retracted to suture; bilieus wide with an almost central funicle about — 
half its own width from umbilical walls all round ; parietal callus thin — 
with Hole narrow eene separating it from funicle. ;
