OF SOUTHERN INDIA. 73 
D’Archiae (Groupe Nummulitique de l’Inde, 1853) deseribes the following 
species, which I do not see how to separate from Gosavia, but which exhibit 
very remarkable differences from Voluta, or any other known rozurinm, both as 
to their form and the distribution of the columellar plaits over the whole extent 
of the inner lip, the anterior plaits being always the strongest: Voluta dentata, 
Sow. (loc cit. 324, Pl. 32, Fig. 2, Pl. 33, Fig. 11); V. Haimei, D’Archiac (p. 325, 
Pl. 31, Figs. 26 and 27); V’. Sismondai, D’ Arch. (326, Pl. 31, Fig. 25); V7. multi-dentata, 
D’Arch. and Haime (826, Pl. 32, Fig. 1); V. Humberti, D’ Arch. et Haime (327, 
Pl. 34, Fig. 9); V. Salsensis, D’ Arch. and Haime (828, Pl. 34, Figs. 10and11). There 
may be a doubt whether the beds from which these have been obtained be truly Num- 
mulitic. On this point I can only refer to the repeated statements of D’ Archiac, 
that Nummiulites occur with them. And if in other respects these beds contain 
Nummiulitic fossils, i. e., are eocene, there is no reason for doubting that those shells 
must be of the same age. We have in our (Geological Survey) collections good 
specimens of Vol. dentata, and these are generically identical with the cretaceous 
Gosavia: of the other species, I have seen only doubtful casts of V. multidentata. I 
may, however, take this opportunity of mentioning, that I know of several strong 
indications of the occurrence of cretaceous deposits in the Punjab and Scinde. 
The sole living representative of Gosavia appears to be Imbricaria, Schum. 
(Conohelix, Swains). Neglecting the notch on the posterior lip in the former, 
and its interior crenulation in the latter genus, the resemblance is indeed very 
marked; and as the animal of Jimdricaria and Cylindra are in some respects 
different from other wzrrimvx, it may after a while be found convenient to unite 
these three genera into a separate group, placing them intermediately between 
the Conzp# and Vorturipz. When the teeth in any of the species of the two 
last mentioned genera have been recorded, it can then be easily settled whether 
they are better kept separate, or be added as a sub-division of the Conzpx, to 
which, I cannot help thinking, they seem to have more relation than to the 
urrrin& of the Voturips. 
1. Gosavia Inpica, Stoliczka, Pl. VI, Figs. 3, 7, and 8. 
Gos. testa conica, elongata, spira brevi, acuminata, fere tertiam partem totius 
altitudinis formante ; anfractibus senis sew septenis, sutura impressa sejunctis, superne 
parun excavatis, inferne seu prope medium carinatis: carina tuberculata; superficie 
spiraliter striata: stris latis, prope suturam atque in carma ternis tenuioribus, trans- 
versalibus partim interruptis, nonnunguam lamellosis ; apertura angusta, recta; labro 
antice producto (Fig. 5. a.), postice ad carinam insinuato ; labio calloso, nvultiplicato ; 
plicis anterioribus fortioribus, approximatis atque obliquioribus quam posterioribus ; 
canali ad terimmationem (7) emarginato. 
Height of last whorl of the largest specimen found, 45 mm. and probable total height 65 mm. 
This species in many respects resembles the European Gosavia squamosa. The 
spire is elevated, consisting of six or seven volutions, the last of which measured 
U
