Mer the arrangement of these cannot be sibi described, but 
seems to be somewhat similar to that of A. maorium. No axial threads 
can be seen, and spirals are apparently not granulated. Five varices 
remain, about "е thirds of a whorl apart, rather narrow, hardly stouter 
than nodules, n t prominent, and slightly sloping forwards. Sutures 
undulating, hardly discernible, but margined by a cord stouter than the 
others. Spire very high (11-2 times height of aperture without canal).

The species seems to be characterized chiefly by its high spire; strong, 
regular, and smooth spiral threads ; and rounded lever some of which 
would be very like this species. It is also somewhat like A. woodsi TA m 
and this species also has a long canal. On the strength of this last 
resemblance Hutton's species is here placed in Austrotriton, but with much 
doubt, since the resemblance to the genotype, A. radiale (Tate) is but 
slight, though there do not seem to be essential generic differences. This 
is one of the “ difficult " forms атй to in the remarks on А. ium 
t is in some respects like a Charonia, but the character of the varices 
seems to forbid placing it in that genus. 
Austrotriton cyphoides n. sp. (Plate 51, figs. 3a, 3b.) 
Shell small, shortly fusiform, with prominent peripheral carina and 
nodules. Protoconch globular, slightly asymmetrical, of about 4 smooth 
convex whorls, but tip is lost. Four whorls succeed this, strongly carinated 
below middle ; shoulder straight, slope almost about 40°, thence slanting 
broad, slightly twisted beak; varices at a little less than every three- 
quarters of a whorl, very low and i inconspicuous, broadly convex towards 
whole surface, producing slightly vie effect. Aperture broken, but 
evidently lirate-dentate within, inner lip spread thinly over columella,
