CRETACEOUS GASTROPODA 
3. ALARIA GLANDINA, Stoliczka. Pl. II, Figs. 14 and 15. 
Al. testa acute-elongata, anfractibus numerosis, ad sutwram posteriorem sensim 
constrictis, levigatis, transversaliter costulatis: costulis acutis, obliquis, 8—12 in uno 
circwitu ; spira ultimo anfractu (sine canali) longiore; ala simplici, falcata, postice 
ad peripheriam uncinata, acuta, interne anfractui penultimo affixa. 
Spiral angle 32°—35°, sutural angle 8°. 
The whorls are rather numerous in this species, when compared with its size, 
and are much constricted on the upper suture. The transverse ribs, which differ 
from 8—12 in number, are oblique and obsolete next the upper suture, similarly as in 
A. papilionacea, but they are always much sharper. No spiral striation is percep- 
tible in any of our specimens, which are well preserved on the exterior surface. The 
anterior canal has not been seen perfect, but it could not have been of greater 
length than is indicated in the outline, and, including the last whorl, it had about 
the same height as the spire, consisting of all the preceding whorls. The wing is 
prolonged posteriorly into a rather long point and anteriorly simply curved towards 
the canal. Only a very slight sinus seems to have been present between the canal 
and the wing. 
The small number and the form of the transverse ribs of the whorls combined 
with the shape of the wing distinguish the Indian species without difficulty from 
Al. costata, Sow. of the Gosau deposits (Zekeli, t. XII. Figs. 1 and 2, Stoliczka, 
Sitzungsb. Ak. Wien. LII, p. 66) or from Ap. Robinaldina, D’Orb. (Pict. Mat. 
Pal. Suisse, Ste. Croix, Pl. 92, Figs. 9 and 10.) 
Localities. N.of Alundanapooram, E of Anapaudy. 
Formation. Trichinopoly group. 
4, ALARIA ACICULARIS, Stolicezka. Pl. II, Figs. 16 and 17. 
Al. testa conica, aciculari; anfractibus numerosis, subplanis, transversaliter 
costulatis, spiraliter minutissime striatis, callositate plus minusve obtectis atque politis ; 
ultimo anfractu subinflato, spira breviori ; rostro brevi (7), labro expanso, postice ad 
anfractum penultimum affixo. 
Spiral angle 35°—40°, sutural angle 5°. 
This little form seems to be occasionally nearly as much covered with an enamel 
coating as the Rost. palliata, with the exception, that the covering is more equally 
distributed over the entire surface of the shell. The whorls are nearly flat, separated 
by slight impressions, which mark the sutures. The apex on well preserved 
specimens is perfectly covered, and the ventral or front side of the shell equally so. 
Where the coating is thinner transversal ribs in rather an oblique position, and a 
very fine spiral striation, are perceptible. The last whorl is somewhat convex, 
shorter than the spira, subangulated below, and apparently anteriorly produced into 
a short pointed canal only. The outer lip is expanded, reaching posteriorly not 
above the previous volution; its margin has not been seen preserved. ‘This species 
resembles greatly Ap. acuta, D’Orb. (Mat. p. 1. Pal. Suisse, Ste. Croix, II. p. 597, 
Pl. 93, Fig. 1), which differs by somewhat higher whorls and proportionally a greater
