shell), by an angular (sinuated) striatum of the shell in each whorl, and by the thickness of 
the shell. The specimens were labelled “Hills near Namcho Lake, Tibet.” Other work, 
especially on the different local floras of India, compelled me to delay the determination for 
a future occasion. 
When later the paleontological collections of the Asiatic Society of Bengal were amal¬ 
gamated with those of the Survey in the Indian Museum, I found amongst them a much 
better preserved specimen of the same kind as mentioned above; but no locality was 
attached, only the inscription “ Glaucouia” sp. P 
This discovery induced me to return to the examination of the Pandit’s fossils, and they 
yielded the interesting result that the fossils belong to that genus, which was established 
first by Zekeli in his paper on “ Gasteropoda of the Gosau formation, 1852 ” with the name 
Omphalia, Zclc., with which Glauconia, Gieb., is synonymous.

I think I am right, using the generic name Omphalia, as Zekeli established it, 
and not Glauconia, Giebel, which was published, it is true, in the same year, but Zekeli’s 
paper was presented already, partly at least, in 1851, although published only in 1852. 
Prof. 1’euss and Dr Stoliczka, in their papers 1853 and 18(15, did the same, only in 1868 
Dr. Stoliczka adopted, in contrast with his paper of 1865, the genus Glauconia, including 
Omphalia, Zek. 
Quite unnecessarily and superfluously M. Coquand, 1865 (1. c.), established a quite new 
genus Cassiope, uniting with it, without sufficient grounds, Zekeli’s Omphalia. Zekeli first 
gave most figures of this genus, and so his name is to be used by all means. 
The characters of the genus are the following :— 
“ The shell is always shortly conoidal or turreted, very thick, with spiral ridges or ribs; 
the columella generally hollow, aperture round-ovate ; the exterior lip with two emarginations, 
of which one lies above, or rarer in the middle of the right labial margin, the other on the 
base. The striae of growth are sinuated (waved) according to the emargination.”
