Hurron.—On new Tertiary Shells. 825 
Part II. 
[Read before the Wellington Philosophical Society, 13th February, 1885.} 
Tue following new species are chiefly from the collection in the Canterbury 
Museum, which Dr. von Haast very kindly allowed me to examine. But I 
have also added a few which I obtained in the Hawke’s Bay District last 
January. 
Tornatellina ovalis. 
Shell ovate rather thin, spirally grooved ; whorls 5, rounded ; the two 
first smooth, the others with smooth spiral ribs much broader than the 
grooves, which are longitudinally striated ; ribs about 16 on the body 
whorl, and 6 or 7 on the penultimate whorl. Aperture ovate, pointed 
behind ; columella with a single strong, sharp, fold about half-way up. 
Length, ‘17 inch; breadth, 08 inch. 
Locality. White Rock River. 
Ancillaria lata. " 
Shell broad, tapering anteriorly; the spire short and obtuse, covered 
with a large callus extending over the posterior portion of the body whorl. 
The rest as in A. australis. 
Length, 1:65 inch ; breadth, :9 inch. 
Locality. Petane and Wanganui. 
Distinguished from australis by its greater breadth and obtuse spire, 
but there are intermediate varieties. 4. hebera, with which it has been 
confounded, differs in having the sides nearly parallel and the spire 
longer. 
Voluta aculeata. 
Shell small, fusiform, the spire produced, acute ; whorls 6 (?), longitu- 
dinally ribbed, the posterior end of each rib rising into a sharp tubercle 
pointing outwards ; ribs low, rounded, 8 in a whorl; suture covered up. 
Aperture rather narrow, the outer lip not reflexed ; columella with four 
plaits. 
Length, ‘8 inch ; breadth, -33 inch. 
Locality. White Rock River. 
Voluta kirkii, v. kirki, Hutton, Cat. Tert. Moll., p. 7, 1878. 
Shell ovato-fusiform ; spiral short, acute, the whorls smooth ; body 
whorl longitudinally subplicate, rounded at the shoulder and narrowing 
anteriorly ; the plications rising into a row of tubercles below the shoulder ; 
there are 8 or 9 in a whorl. Aperture moderate, with a posterior callus. 
Columella plaits not seen. 
Length, 8:5 inch; breadth, 2:0 inch. Length of aperture, 2-6 inch. 
Locality. Porter River.
