78 Miscellaneous. 
very extensive collection of the freshwater shells of India—the first, 
I believe, that was sent to this country. 
It is figured by Mr. W. Wood, however, in the Supplement to the 
Catalogue of Shells as Turbo Francesi, from specimens sent home 
by Mrs. Ince: so the confusion began early. Mr. Wood (unfortu- 
nately for science, as it added some confusion to the nomenclature) 
submitted the proofs of the text of the Supplement to Dr. Goodall, 
who, I suppose, not knowing that the names which I had supplied 
to Mr. Wood had already been published (though it is mentioned 
in the preface that they are the names used in the British Museum 
collection), altered some of the names capriciously. I suppose that 
the Provost of Eton College did not think it right that a shell should 
be named after a woman; for in the same way he altered Nerita 
Smithiea and Turbo Maugere to Nerita Smithii and Turbo Maugeri. 
No one who knew him can believe that it arose from want of polite- 
ness or gallantry ; but conchologists are more liberal now. I may 
observe that all the shells figured from specimens in the Supplement 
were engraved (not etched) on the copper at once, from the shells 
selected by myself either from the British Museum, Mrs. Mawe’s, 
or Mrs. Gray’s collection; and I furnished him with the names of 
the species (which in some cases were so oddly changed) and also 
with the Lamarckian Index to the Catalogue and Supplement. 
On the Species of the Genera Latiaxis, Faunus, and Melanatria. 
By Dr. J. E. Gray, F.R.S. &e. 
The examination of the original specimens on which the various - 
species of the genus have been described and figured has convinced 
me that there are not more than two distinct species of Latiazis. 
The first, ZL. Maire, is nearly smooth, with a flat depressed spire 
and avery large umbilicus: L. purpurata, Chenu (Mollusques Mar.), 
appears to be only a variety of this species, which is sometimes of a 
purplish colour. The second, L. pagoda, Johnson, has a conical 
spire and a small umbilicus. L. pagoda, Johnson, L. textilis, A. & 
H. Adams, L. Eugenie, Beraud, and L. nodosa, A. Adams, are all 
varieties of the same species, varying in the presence or absence of a 
keel on the last whorl, and in the whorls being slightly nodose. 
They are all inhabitants of the China Seas. 
The specimens of the genus Faunus, Montfort, in Mr. Cuming’s 
cabinet show most conclusively that the shells named Faunus ater, 
F. terebralis, Lamk., F. Cantori, Benson, and F. pagoda, Reeves, 
are only slight varieties of a single species. F'. Oantori is a dwarf 
decollated state, and F’. pagoda is described and figured from an acci- 
dentally distorted adult shell. They are found in Ceylon, Penang, 
the Philippines, and New Caledonia. 
The species of Melanatria, Bowdich, have been also needlessly 
divided. There can be no doubt that M. fuminea and M. plicata, 
Reeve, are only varieties of M. spinosa, Lamk. It is found in 
Madagascar and West Africa, They vary not only in the strength
