XXXV. — Characters of new Land- Shells from the Andaman 

 Islands, Burmah, and Ceylon, and of the Animal of Sophina. 

 By W. H. Benson, Esq. 



1. Helix hemiopta, B,, n. sp. 



H. testa anguste umbilicata, depresso-conoidea, vix striatula, Isevius- 

 cula, minutissime granulata, opaca, albida ; anfractu ultimo su- 

 perne castaneo, versus peripheriam saturatiore ; spira convexo- 

 conoidea, apice obtuso, sutura vix impressa ; anfractibus 4^, con- 

 vexiusculis, sensim accrescentibus, ultimo superne prope peri- 

 pheriam obtuse angulatam concaviusculo, subtus convexiusculo ; 

 apertura obliqua, subquadrato-lunata, intus concolore, peristomate 

 expansiusculo, superne antice arcuato, subtus breviter reflexo, 

 marginibus remotis, columellari superne valde dilatato, umbilicum 

 subtegente. 



Diam. major 16, minor 13|, axis 10 mill. 



Habitat ad Portum Blair Andamanicum. 



Two dead specimens of this shell, only one of which has the 

 aperture complete, were collected by Major J. C. Haughton. 



A nearly allied shell, with the surface in good condition, 

 obliquely substriated, shining, and sprinkled with minute in- 

 dentations, may possibly be a variety ; but the aperture is in a 

 state too imperfect to allow a satisfactory decision. It is milk- 

 white, with a single dark band above the periphery and running 

 along the edge of the upper whorls, which are slightly more 

 convex, and divided by a more depressed suture. A single spe- 

 cimen from Port Blair was received from Major Haughton. 



2. Helix Aulopis, B., n. sp. 



H. testa perforata, depresso-conoidea, oblique minute striatula, striis 

 confertissimis spiralibus decussata, pallide cornea, nitidula, trans- 

 lucente, versus apicem rubente ; spira conoidea, apice acutiusculo, 

 sutura leviter impressa ; anfractibus 5, superne subplanulatis, vix 

 convexiusculis, ultimo subtus convexiusculo, ad peripheriam cari- 

 nato ; apertura obliqua, quadrato-lunata, peristomate recto, tenui, 

 acuto, marginibus subremotis, callo tenui junctis, columellari su- 

 perne breviter dilatato. 



Diam. major 12, minor 10, axis 6 mill. 



Habitat ad Portum Blair. 



A single specimen of this shell, in good condition, was re- 

 ceived from Major Haughton. It has some affinity to the 

 Javanese H. helicinoides, Mousson. 



A perfect example (from the same source) of Helix Helferi, m., 

 described in the 'Annals^ for September 1860, has a dark cor- 

 neous epidermis, dull and lustreless, and the scattered hairs are 

 like short dark-coloured prickles. The peristome is liliaceous 

 white and polished. This and other specimens of the shell ob-
