162 CRETACEOUS GASTROPODA 
rocks of New Jersey, “ occurring in the state of casts,” etc. From the deficient state 
of preservation, in which the species of Turbinopsis have been found, it is really very 
difficult to ascertain, whether they belong to this family at all. The spiral striz, or 
revolving lines as the American paleeontologists usually call them, present in both of 
the species and the want, or at least non-appearance, of transverse ribs indicates 
rather a different character of ornamentation, from what is usual in the family 
Oancettartipe. 1 would not be in the least surprised, if the two species were shown 
to belong to the family Trocurpx or Lrrroriwrpz, (Modulus). We describe in the 
following pages five species of Oawozzrarupz from the South Indian cretaceous 
beds. In transferring two species, formerly described by Prof. Forbes as Voluta 
breviplicata and V. Camdeo, to this family, we do so in accordance with the general 
habitus of the shell, the character of ornamentation, the anterior position and un- ~ 
equal strength of the columellar folds, and the thickness of the posterior portion of 
the inner lip. All the Indian Cayceztarmpz belong to the upper series of the cre- 
taceous beds, and mostly to the Arrialoor group. 
The Cane. torquilla, Zekeli, from the Alpine-Gosau deposits must be excluded, 
being a Fasciolaria or possibly a Latirus ; there are, however, two as yet undescribed 
species of Cancezzarup# known to occur in the same deposits (vide Sitz. Akad. 
Wien, 1865, LII, Revis, &c., p. 80) ; and these being included we may fix the number 
of presently known cretaceous species belonging to this family at thirteen, four 
being European (one doubtful), four North American (two doubtful), and five 
South Indian, thus at least approximately showing that the family appears to have 
been more numerous in the tropical regions during the cretaceous time, precisely 
as during the present epoch it is nearly exclusively confined to those seas. Only a 
few species are known from the Mediterranean sea.

1. CANCELLARIA ANNULATA, Stoliczka, Pl. XIII, Fig. 11. 
Canc. testa ovali, spira brevi-subacuta ; ultimo anfractu ventricoso, spira altiore ; 
anfractibus spiraliter striatis, transversim costulatis ; striis elevatis, filiformibus, in- 
terstitiis latioribus separatis ; costulis circiter ternis in uno curcuitu crassioribus, 
varicosis, ceteris tenuioribus atque inter se nonnunquam mequalibus ; columella ar- 
cuata, triplicata. 
Spiral angle 65°; sutural angle about 10°. 
Shell ovate, the last whorl ventricose and largest. There are only about five or 
six whorls present, and all of them are ornamented with spiral elevated strice and 
transverse ribs, exactly similar to those in typical Cancellarie. The spaces between 
the spiral striee are broader than the thickness of the strize themselves, which being 
erossed by the transverse ribs produce a reticulated surface of the shell. The ribs 
are, however, always stronger than the striae, and generally about three of them in
