210 Mr. W. H. Benson on new Species of Landr Sheik, 



cimens, one of which exhibits the large dimensions recorded 

 above. 



Helix Neherensis, B. 



JET. testa anguste et perspective umbilicata, depressa, lenticulari, 

 oblique striatula, lineis concentricis vix impressis, confertissimis, 

 superne et infra decussata; spira convexiuscula, apice planato, 

 sutura marginata subcanaliculata ; anfractibus 5, coiivexiusculis, 

 ultimo ad peripheriam rotundato, subtus convexo, circa umbilicum 

 excavate ; apertura obliqua, late lunata ; peristomate tenui, recto, 

 marginibus callo tenui minutissime granulate junctis ; columellari 

 subverticali, brevi, reflexiuscule. 



Diam. major 5, minor 4, axis 2 mill. 



Habitat ad Neher, Mahabaleshwar. Detexit S. B. Fairbank. 



This peculiar little species, which I have, at the suggestion of 

 the discoverer, named after the place where it was found, appears 

 to have escaped the observation of Mr. W. T. Blanford, who 

 collected several new land-shells during a hurried search at the 

 same locality, which is noted for its abundant rainfall during 

 the monsoon. The delicate concentric lines are visible under 

 a lens. 



Carychium Boysianum, B. 



C. testa subrimata, elongato-cylindrica, sub lente oblique minutis- 

 sime striatula, translucente, nitida, albida ; spira elongata, grada- 

 tim attenuata, apice obtuse, sutura impressa ; anfractibus 5, con- 

 vexiusculis, subplanulatis ; apertura subverticali, ^ longitudinis 

 non eequante, oblenge ovato-acuta ; peristomate expanse, planu- 

 late, nennunquam subduplici, margine dextre.intus 1-tuberculato, 

 parietali plica 1, columellari altera obliqua munitis, callo parietal! 

 expanso. 



Alt. 2, diam. vix | mill. 



Habitat prepe urbem Agra, ad ripas fluminis Jumna. Detexit Capt. 

 W. J. Boys. 



This species, discovered at the Taj, near Agray by the late 

 Capt. Boys, is closely allied to the Himalayan species C. Tndicum, 

 B., but is distinguished by its more elongated cylindrical and 

 less rapidly attenuate form, and its flatter whorls, also by the 

 narrower and more acute aperture, the right lip being straighter 

 and less convex, and by the expanded parietal callus. 



Mr. Fairbank sent me a rough variety of Ancylus Verruca, B., 

 of the Lower Himalaya and Rohilkhund, with the small variety 

 of the Gangetic Planorhis nanus, which were taken by him in 

 the Mahabaleshwar waters, with the shell imperfectly described 

 by Mr. E. Layard, in the ^ Proc. Zool. Soc' for 1 854, as AncU' 

 lotus carinatus, which bears some resemblance to Mr. Anthony's 

 North-American shell of the same name. I consider the Indian 

 species to be a Melania. They were accompanied by a new
