SECOND YARKAND MISSION. 
I have named this pretty little shell after my friend Colonel Mainwaring, B.S.C., who 
has lately discovered very many interesting, rare and new forms round Calcutta, in Behar, 
and near Darjiling. 
19. Buliminus (Petrous) beddomeanus, n. sp., Eig. 29. 
This is a very interesting species, resembling somewhat, in shape of the whorls and 
aperture, B. smithei, “ Conchologia Indica,” pi. xx, fig. 3, hut it is still nearer B. eremita, Bens., 
1. c., fig. 8, from which its produced spire, narrower whorls, and aperture easily distinguish 
it. Narrowly rimate, subcylindrically turreted, of solid, scarcely polished substance; closely, 
obliquely striate, striae more regular and crowded together than in the two preceding forms ; 
of a very pale horn colour, only here and there discernible, on account of the crowded striae, 
which are of a chalk white colour ; spire much produced, apex obtuse ; whorls 10, increasing 
very gradually and regularly, last whorl compressed; aperture very small, peristome white, 
outer m argin broadly reflected, very slightly arcuate (much as in pi. xx, fig. 3, l. <?.), columella 
dilated, obliquely rounded at base. 
Long. 13f, diam. 4 f (last whorl to base of aperture, 5); apert. alt. 3^, lat. 2f mm. 
Rather scarce near Murree. 
I have named this shell after Colonel Beddome, who has contributed so extensively 
to our knowledge of the plants, reptiles and mollusks of South India. 
20. Buliminus (Peileus) pretiosus, Cantor. 
Eour specimens were found at Tinali, and a single one, of a slightly different form, near 
Murree. 
21. Bulimintjs (Petrous) rufistrigatus, Bens. 
A single specimen of the typical form from the Jhelum Valley, and two specimens from 
Kashmir of the var. gracilis of the “ Conchologia Indica.” 
22. Buliminus (Petrous) domina, Bens. 
A few specimens were found alive near Murree. 
23. Buliminus (Petrous) candelaris, Pfr., var. 
A peculiarly shortened form found very abundantly near Tinali ; the dextral form 
appears to have been found more abundant than the sinistral. Mr. Lydekker, of the 
Geological Survey of India, informs me he has noticed that the two forms are not usually 
found absolutely together.
