Austrodrillia vawitensis Hedley 
(=Drillia angasi S u t e r). 
North Island: 16, 1 shell, h. 12. Hedley States (1922) that 
Hutton’s and Suter’s Drillia angasi is dilTerent from the type 
by Crosse and proposes the name used here. 
Melatoma (Splendvillia) laevis Hutton. 
North Island: 4, 1 shell, h. 12. — 10, 1 shell, h. 17. — 16, 
1 Shell, h. 6.5. Hedley (1922) proposes the subgenus Splendrillia 
for comprising this and some related species. 
Sgrinium (Belå) neozelanicum Suter. 
North Island: 11b, 1 shell, h. 9.5. This species has been re- 
ferred by Hedley (1922) to the genus Scrinium Hedley. 
Heterocithava mediocvis n. sp. 
(PI. I, fig. 29.) 
Shell small, turreted, apex pointed, spira exceeding the aperture 
a little in height. Sculpture: apical whorl first smooth, then spirally 
punctured; two next whorls with fine spiral striae and numerous 
thin equidistant, somewhat flexuous, longitudinal costae; fourth and 
subsequent whorU with coarser, more distant axial ribs and 4—5 
spiral threads, the second one strengest, forming nodules when 
Crossing the axial ribs; axial costae continuous over all the spire, 
their number in the penultimate whorl 11; spiral lines on the 
body whorl 10 (besides one or two intermediate ones) as well as 
6—7 on the canal. Interstices everywhere with fine spirals of 
microscopic grains. Suture rather deep. Colour white. Aperture 
narrow, vertical, with a deep sinus in the broad varix limited at 
each side by a short tooth; on the inside of the lip one further 
tooth .(or indistinct). Edge of outer lip with some short furrows 
corresponding to the spiral ribs, sinuous below. Canal short. Di 
mensions: H. 5.5, br. 2.3 mm. — Locality: North Island: 16, 4 
dead shells. 
This species comes near in sculpture and shape to H. seriliola 
and concinna of Hedley (from Queensland) described in his splendid 
and useful revision on the Australian Turridae (1922).
