OF SOUTHERN INDIA. 457 
c.. Sub-family,—MURICIN Z. 
The genus Odontopolys, Gabb (Am. Jour. Conch., I, 1865, p. 16) is placed by 
Conrad in this sub-family, but judging from the form of the type-species O. compsor- 
phytis (Jour. Ac. N. Se. Phil. IV, pl. 67, fig. 16), the genus appears to be closely 
allied to Hindsia. 
Murex fluctuosus, Forbes, mentioned on p. 129, is represented in the Geological Society’s Col- 
lection only by the figured fragment, probably belonging to some species of Z'ritonidea ; it is distinct 
from any of the species described by me. 
Meek (List of North Amer. cret. fossils, 1864, p. 22) mentions Clavellithes (or 
Piestocheilus), Pyrifusus, Tritonifusus, and others. He quotes 82 North American 
cretaceous species belonging to the Murrcerpz. 
XI. Family,—_TRITONIIDA, p. 180. 
(RANELLACEA and TRITONIACEA of Troschel). 
Valenciennes proposed (Compt. rendus, 1858, p. 762) the name Tvitonellium 
in place of Zritonium, Miller, 1776 (Lamk., 1807), so as to prevent mistaking it 
for Tritonia, Cuv., 1798, but this change is not necessary. 
The American Conchologists have largely added to the number of this family. 
Trachytriton, Meek (Check list cret. fossils, N. Am., 1864, p. 37) has been 
proposed for Fusus ? vinculum, Hall and Meek, being a bucciniform, rather thin 
shell, the canal nearly straight, columella smooth; surface without distinct varices ;” 
this genus appears closely allied to Hindsia, the principal distinction being a 
smooth lip. 
Conrad quotes (Am. Jour. Conch., I, 1865, p. 20) Buecitriton,* Tritonopsis, 
Personella, Sanellina, Sagenella, and in Check list eocene fossils of 1866 (p. 17) 
Ranellina. — 
Tritonium cretaceum, Miiller, p. 133; the original has the outer lip broken away, but it 
probably belongs to Zpidromus. 
Triton atavus, Forbes, p. 134, is founded upon a hopeless cast, possibly belonging to Cerith. 
vagans. 
Fusus pedernalis, Romer, p. 134, is determined from an impression left on a Gryphea.

XII. Family, —_COLUMBELLID. 
Morch (Jour. Conch., VII, p. 254) divides the old genus Colwmbelia according to 
the dentition into Pygmea, Humph., Witsella, Risso, and Pyrena, Bolt., each with 
a number of sub-genera. We would be disposed to retain those sub-genera as genera, 
but the generic names, referred to, cannot be introduced in that author’s sense. 
Meta, Reeve, is an intermediate form between Stromboidea and Conella ; 
typical species are Conus macrostomus, Auton, Con. Dupontie, Kiener, and others.
