20 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., Fig. 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., 

 I. c., fig. 8, from which its produced spire, narrower whorls, and aperture easily distinguish 

 it. Narrowly rimate, suhcylindrically turreted, of solid, scarcely polished suhstance ; 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 croAvded 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 margin broadly reflected, very slightly arcuate (much as in pi. xx, fig. 3, I.e.}, columella 

 dilated, obliquely rounded at base. 



Long. 13f , diam. 4| (last whorl to base of aperture, 5); apert. alt. 3J, lat. 2f mm. 



Hather 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 (PET^US) PRETIOSUS, Cantor. 



Four specimens were found at Tinali, and a single one, of a slightly different form, near 

 Murree. 



21. BULIMINUS (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.
