OF SOUTHERN INDIA. 301 
In Europe likewise Amp. bulbiformis is one of the most common species all 
through the Alpine upper cretaceous deposits, and also in 8. W. France, in Hungary 
and in Transylvania. I also found among the cretaceous shells, brought from Texas 
by Prof. F. Romer and presented to the Museum in Bonn, two casts which most 
probably belong to this species. 
Formations.—Ootatoor -, Trichinopoly — and Arrialoor — groups.

Amp. testa globosa, levigata, spira brevi, acuminata, viv tertiam partem totius 
altitudinis occupante; anfractibus convexiusculis, ultimo valde inflato, convezo ; 
apertura semilunari, labio crasso, calloso, fissuram columellarem tegente. 
Spiral angle 90°- 95°; sutural angle 8°. 
Height of aperture : total of shell .., «(considered as 1:00) about 0°70. 
Approximate height of last whorl: its width ( 5 eld in rss Osioe 
Largest specimen measuring 80 mm. in height and about 70 mm. in width. 
This species is distinguished by the great size of the last volution and the com- 
parative shortness of the spire. The upper whorls are six or seven in number, 
convex and separated by impressed sutures; the last is evenly rounded, somewhat 
more globose on the back, than in front. The aperture is very large, semilunar, 
anteriorly rounded, posteriorly angular; the inner lip very thick ; the fissure scarcely 
traceable, being covered by the inner lip. 
The recent Amp. fluctwata, Sow., is nearly allied to this species, but it is broader 
and has a shorter spire. Amp. mastoidea, Pict. and Camp. (Mat. Pal. Suisse, 3me. 
Ser., p. 381, pl. 76, figs. 2 and 8,) from the ‘étage Urgonien’ at Ste. Croix, is 
also a large, allied form. 
Locality —Ninnyoor, in whitish arenaceous limestone; not rare with Wer. 
Blanfordiana, Turr. elicita, Cypree, and other species, which mostly resemble such 
forms as at present live in the neighbourhood of, or on, coral reefs. 
Formation.—Arrialoor group.
