are labelled ‘‘types,” and these are certainly very distinctive in appearance, 
having' a short spire, the umbilicus sealed, but with the mouth open, the lips 
expanded in a manner quite unlike that of the species convicta and incon- 
victa, with which it has been confounded. 
The spire is snbconical, a little elevated, the perij)hery subkeeled in the 
earlier whorls, the last whorl well rounded, the mouth a little descending, 
the outer li}» expanded all round giving it a flaring a.ppearance; the 
columella reflected, flattened, entirely closing the umbilicus, which is very 
narrow and open in the young. The .shell is chalky white, somewhat bright, 
not dead, and there is no sculpture save Faint growth lines. The tyiie 
measured 22 mm. in breadth and 15 mm. in height. 
Many shells from “On trees olf the Limestone Caves,” north end of the 
Napier JKange, collected by Dr. H. Basedow.

A single specimen collected by Dr. H. Basedow “in rocks” at Lime- 
stone Caves, North end Napier Range, differs in size and coloration from 
those collected on trees somewhere in the same locality. Shell small, 
whorls rounded, sutures deep, spire a little elate, coloration brownish cream 
fading on the last whorl, mouth open, li]) thin reflected all round, umbilicus 
sealed. The sculpture is of the same kind, but appears to be a little coarser 
than in the larger shells, while the apical whorls ai'e smooth and .shining, 
a minute radial striation being only obscurely seen under a strong lens. 
Breadth 17 mm.; height 11 nun.

A fine series, collected by Dr. Hei'bcrt Basedow in the Barker River 
Gorge, ]\Iid Napier Range, differs from another long series secured by the 
same collector “on trees off the Limestone Oaves” at the northern end of 
the Napier Range, in their .smaller size but more in their shape. The whorls 
are more flattened, the sutures less impressed, the spire more deju'essed and 
rounded, the last whorl showing a little subkeeling, and the mouth not so 
thrown out, more in line with the sfiire, the outer li]) however flaring as in 
woodivardi, and the umbilicus sealed. The typo is a dead shell measuring 
20 n;m. in breadth by 14 mm. in height.

Another lot of shells, collected by Di'. H. Basedow and labelled Barker 
River Gorge, are all dead, and divisible into two series, obviously collected 
at two different places in the Gorge. One series consists of large shells all 
weathered white, varying from 20 to 22 mm. in breadth and fi'om 14 to 
16 mm. in height. In form, height, apiJcarance these a.gree very closely with 
woodu'arili, but differ in the fact that the columella instead of being 
appressed, sealing the umbilicus, runs into the cavity and covers half the 
umbilical opening but leaves it quite unsealed. So many shells have been 
collected that this character is of valid s))ecific worth in this ease, though 
often such is not the ease, and each instance must be judged separately.
