Mr. W. H. Benson on new species of Helix. 159 



This shell, like labiata, monticola, and other Himalayan Helices, 

 has frequent varices, the edges of former apertures, distinguished 

 by obliquely radiate bands of a darker colour. It was received 

 by Dr. J. F. Bacon from Darjiling. A specimen from Dr. Pearson 

 is in the East India Company's Museum in Leadenhall-street.

 cente-albida, antice rufescente, versus apicem rufo-castanea, 

 punctis plurimis brunneis translucentibus quasi solata, fascia 

 unica castanea supra angulum anfractus ultimi usque ad apicem 

 decurrente, 1-3 obsoletis subtus ornata ; anfractibus 5 convex- 

 iusculis, ultimo subangulato, angulo antice evanescente ; spira 

 obtusata; apertura obliqua, transverse ovato-lunata, peritremate 

 intus fusco-castaneo, albo-marginato ; labro recto, deflexo, mar-

Diam. major 23 mill., minor 18. Axis 11 mill. 



Hab. montibus Nilgherries Indise meridionalis. D. Jerdon. 



I owe this species to the kindness of Dr. Jerdon, who sent it 

 to me, with other interesting shells, from the Madras Presidency. 

 He found it on the western face of the Nilgherries. I have a 

 larger specimen from the same source in bad condition. 



3. Helix crassicostata, nobis, n. s. 



Testa late umbilicata, depresso-planata, albida, plicis validis irregu- 

 laribus obliquis, juxta carinam incrassatis, munita ; spirse apice 

 laevigata, vix elevato ; anfractibus 4 planatis, ultimo carinato, 

 subtus valde convexo, antice deflexo ; umbilico infundibuliformi ; 

 apertura subhorizontali, transverse ovato-rotundata, marginibus 

 conniventibus reflexis, callo brevi junctis. 



Diam. major 13 mill., minor 10. Axis 4 mill. 



Hab. in dumetis Indise meridionalis. Jerdon. 



This species belongs to the same group as H. ruginosa, H.fal- 

 laciosa and H. asperella, all inhabiting Hindustan. It is most 

 nearly allied to the former, but differs in its flatness above, its 

 keel, colour, and wider umbilicus. Dr. Jerdon sent it to me, with 

 H. ruginosa, from the jungles of Salem. Leschenault is quoted 

 as an authority for the occurrence of H ruginosa in Bengal, but 

 it has never been met with by me nor by my correspondents in 

 that Presidency. H. fallaciosa is also noted as a Bengal species 

 by Pfeiffer in the ' Zeitschrift fur Malakozoologie ' for 1846, but 

 in his monograph, Coimbatore and Ceylon are given on the au- 

 thority respectively of Leschenault and Templeton. Dr. Jerdon 

 sent it to me as occurring in jungles in the Carnatic. For H. as- 

 perella Dr. Pfeiffer has given only the locality of the specimens
