O.f Spirifer MoosaJcTiailensis, Davidson, or a closely-allied Salt Range, in the 
species. Punjab. 
I should have added to these a large and remarkable Spiri- 
ferj abundant in Dr. Gerardos Oxford collection, but that 
Prof. Oldham finds it in the same beds with the Triassic 
Ammonites ! It is clear we have yet much to learn of Indian 
Geology. The only two species that need description in the 
foregoing list are a brachiopod and a lamellibranchiate shell. 
1. CHONETES VISHNU—A. Sp. 
PI. 5, fig. 12. 
C. semiuncialis, profunde biloba, transversa, auriculis nullis, striis angularibus 
irregulariter bifurcatis et intcrlineatis: striis incrementi distinctis. 
Transverse, the ears square, not produced. Half an inch 
broad, and about a quarter long, convex, strongly bilobed— 
the furrow reaching to the very beak—striate. The stride are 
angular, with equal spaces between them : they bifurcate 
very irregularly at all distances from the margin,—and are 
wavy and rather nodular,—crossed by somewhat distant 
coarse lines of growth, and by very numerous close concentric 
strise. 
Interiorly, lines of small and rather remote puncta are 
placed in the furrows between the ridges. 
This species differs from all allied forms described by De 
Ivoninek, in the strong bilobation and the coarseness of the 
* Gerard’s collection, Oxford Museum. In the Trans, of tbe Asiatic Society, 
the Rev. It. Everest mentions Producta scotica, and Orihoceratites. It is 
quite probable that both these may occur, 
f Prof. Oldham’s collection. 
% I can hardly distinguish it from & Keilhavii of the mountain limestone 
of Spitsbergen.—See p. 53, woodcut.
