ALARIA. ele, 
is well exemplified in ‘‘ Rostellaria’’ composita, Sow., a lower Oxfordian fossil, 
Alaria seminuda, Héb. and Desl., and probably others. 
35. ALaRiA HAMUS, Desl., var. Noposa. Plate IV, fig. 9. 
A single specimen, said to come from Stoford, in the Buckman Collection, 
presents some curious analogies with, and yet some marked differences from, A/. 
hamus. It is a stouter and larger shell than the average of South-Dorset 
specimens. Number of whorls ten to eleven; not only are the apical whorls 
smooth and without ornament, but this peculiarity extends to the subapical whorls, 
so that the turrited character characteristic of the hamus-group is not developed 
until much later. The longitudinals are extremely thick and nodose. The wing 
overlaps the lower half of the penultimate, a feature not preserved in the Burton 
Bradstock specimens ; there seems also to have been an anterior spine on the keel 
of the body-whorl instead of a mere spinous swelling. 
36. ALARIA PINGUIS, sp. nov. Plate IV, fig. 10; and Plate VII. fig. 11. 
Description.—Since the available specimens are probably incomplete, dimensions 
cannot be given, but the spiral angle is about 45°. Spire wide-angled and conoidal, 
and consisting of eight whorls; the apical whorls, as usual, plain; subapical 
whorls convex and either plain or spirally striated; the anterior whorls possess 
coarse longitudinal tuberculation in addition to the spiral ornaments. Body-whorl 
bicarinate, keels plain or nearly so. 
Relations and Distribution—Through the var nodosa there seems to be some 
connection between these shells and the regular Al. hamus. Yet, omitting that 
possible intermediary, the differences are so great as to warrant a somewhat 
stronger distinction. Since none of the processes are known, the species must be 
regarded as tentative and incomplete. 
Rare in the Parkinsoni-zone of Dorset. The specimen, Pl. IV, fig. 10, is 
from Stoford, horizon unknown; the specimen, Pl. VII, fig. 11, is from P,, 
Vitney Cross.
