7. TURRITELLA ELIcrTA, Stoliczha, Pl. XIV, Fig. 3, and Pl. XIX, Figs. 15-16. 
Turr. testa perlonga, valde attenuata ; anfractibus numerosis, postice late tumes- 
centibus, ad medium paulo excavatis, superioribus spiraliter minute striatis atque 
liratis, inferioribus levigatis ; striis inerementi minutis, supra medium valde insinu- 
atis ; ultimo anfractu ad peripheriam basalem subcarinato ; basi paululum producta ; 
apertura subquadrangulari, altiore quam lata. 
Spiral angle 9°; sutural angle 12°-13°. 
Height of one whorl : its width (considered as 1:00) coo nie puns 
The very elongated form and the broad swelling along the posterior suture give 
_ this species at first sight the appearance of a Nerinea; the sutural swelling is, how- 
ever, not margined by a separate line, as is the case in all Nerinee, and the want of 
all columellar plaits confirms that distinction. 
A very characteristic mark of this species is produced by the great height of 
the whorls in proportion to their width, which distinction separates it readily from 
T. biformis, Goldf. (Petr. Germ. ITT, pl. 197, fig. 8), and also from the intertrappean 
T. prelonga, Hislop, with which Mr. H. Blanford thought it apparently identical 
(vide Mem. Geol. Sur. India, IV, p. 141). The uppermost whorls are minutely 
spirally striated on the elevated band, and more strongly on the rest of the surface, 
but on the larger whorls ‘only the insinuated strie of growth are distinctly 
traceable (vide Pl. XIX, Fig. 16). The basis of the last whorl is slightly convex, 
obtusely carinated at the periphery and apparently smooth. 
Locality.—In the white sandy limestones near Ninnyoor, where the species 
was found with Nerinea Blanfordiana, and several Crprarpa and VoLuripe. 
Formation.—Arrialoor group. 
8. TURRITELLA CONTUMESCENS, Stoliczka, Pl. XVI, Fig. 17; Pl. XIX, Fig. 17. 
Turr. testa anfractibus numerosis, complanatis composita ; margine posteriori 
anfractuum tumescente, tuberculis transversaliter elongatis atque obliquis ornato ; 
superficie anfractuum infrd quatuor striis granulosis fortioribus atque nonnuilis 
minutissimis notata. 
Spiral angle 20°; sutural angle 10°. 
Height of one whorl : its width (consd, as 1:00) i w. 0°40. 
The ornamentation of this species recalls very much some other similar 
cretaceous forms, like 7. Decheniana, Goldf. (Pet. Germ. pt. III, p. 107, pl. 197, 
fig. 8), or 7. biformis, Sow. (ibid. fig. 8; Stoliczka in Sitzgb. Akad., Wien, LIT, 
Revision, etc., p. 8), but the great width of the whorls in proportion to their 
height is a very marked distinction of the Indian fossil. 
The posterior margin of each whorl is ornamented with a broad, tuberculated 
band or ridge, and below it are four spiral granulated stric alternating with some 
other much finer ones. The granulation of these strie, specially of that on the 
anterior suture, is not always very distinctly traceable, although it never appears 
to be wanting. The basis of each whorl is rather flattened and spirally striated ; 
the section of the whorls is roundly angular,
