OF SOUTHERN INDIA. 143 
restriction of the genera it has been found, that the smallest number of fossil 
species belong to Buccimum proper. There is scarcely one true Buccinum from the 
cretaceous beds, to which genus in general the species have been attributed. (Vide 
Mat. p. 1. Pal. Suisse, 3me. ser. pt. ii, pp. 672 and 673). The following are the creta- 
ceous species known up to the present time; most of them belong either to the 
sub-family wasszv# Or BUCCININE :— 
1. Buccinum gaultinum, D’ Orb., is most probably a Nassa. 
Q, o rennense, D’Arch., in all respects a very doubtful species. 
3. Sy Steiningert, Miiller, a Nassa. 
4, Be constrictum, Hall and Meek, sp. (Fusus id. Am. Acad. Arts and Se. Boston, 
v, p- 391, Pl. 3, Fig. 7) may be a Nassa. 
5.—Pseudobuccinum Nebrascense, M. and H. (1857. Proc. Acad. Nat. Sc. Phil. p. 140). 
6.—Buccinopsis Parryi, Conrad, 1857, Emory’s Report, p. 158, Pl. 3, Fig. 4. I have not been 
as yet able to procure this publication, and quote the species on Mr. Gabb’s authority (vide 
Proce. Am. Phil. Soe. VIII, 1861, p. 97). 
7.—Nassa lineata, Sow., 1836 (Buccinum pseudolineatum, D’Orb.) is a true Nassa. 
8.—Buccinum supracretaceum, Binkh., 1861 (Monogr. Gast. et. Ceph. de Limbourg, p. 12, 
Pl. 1, Fig. 7) is apparently a Nassa, and related to Nassa Arrialoorensis, n. sp. 
9.—Buceinum liratum, Gabb, 1864 (Pal. Calif. I, p. 26, Pl. 28, Fig. 211). The posterior lip 
is rather thickened, and it is possible that the species belongs to Budlia. 
10-11.—WNassa eretacea and antiquata, Gabb, cid, p. 97. 
12.—Haydenia impressa, Gabb, ibid p. 98. 
13-14.—Pseudoliva lineata and voluteformis, Gabb, ibid, p. 99. 
To this we add from the South Indian cretaceous deposits three new species, 
15-17.—WNassa Vylapaudensis and Arrialoorensis, and Pseudoliva subcostata. 
To the species of Buccinum, quoted by Pictet and Campiche, as to be excluded, we would add, 
Bue. cancellatum, Alth, which appears to be a Hindsia (vide ante p. 10). 
Nassa affinis, Sow., is not a Cerithium, as D’Orbigny suspected, but a Rissoa and remains 
R. affinis = R. velata, Zek.; vide Sitz. Akad. Wien, 1865, LII, Revis. ete., p. 19. 
Nassa carinata, Sow. ; it is not possible to trace this species without comparing the original 
fragment, although it most probably belongs to Péerocera subtilis, Zek. (Sitzungsb. Akad, Wien, 1865, 
LII, Revis. ete., p. 70). 
Nassa costellata, Sow. ; (Fitton in Trans. Geol. Soc. London., ser. II, Vol. IV, p. 344, Pl. 
XVIII, Fig. 26). D’Orbigny (Prod. II, p. 156) places this species under Cerithiwm, and apparently 
more correctly, for the remaining varices on the whorls, to which Sowerby refers in his description and 
figure, are quite foreign to species of the BucoINID®, but they do occur often among the CERITHIID®, 
and especially among cretaceous forms, as Cerithium reticosum, Sow., Cerith. furcatum, Zek. and others. 
Excluding thus the very doubtful species we may say, that there are up to the present 17 species 
of BuccrnNIDH known from cretaceous rocks, five being European, nine North American, and three 
South Indian ; but I suspect that, when all the forms described from the cretaceous beds of Europe 
under the name of Cerithiwm are better known, several species of N4ASSIN# and PHOSIN# will be 
found represented among them. The comparatively large number of North American species has 
increased only through the late addition of the successful Survey of California, and the careful 
examination of the fossils by W. Gabb. The three Indian species are noticed here for the first time, 
thus adding to the six or seven species of Nassa two more, and to the two North American species of 
Pseudoliva one. Compared with other fossils as regards their frequency of occurrence, the 
BuccrInID# must be said to be very rare, and most of the species are known from single or a few 
specimens only.
