Mr. W. H. Benson on new Land- Shells from Darjiling. 4G1 



liformi profunde intrante, denteque palatali uiiica intus longe et 

 contigiie concurrentibus, aperturam coarctatam inaequaliter oblique 

 dividentibus, aream minorem quasi perforatam prope sinum dex- 

 tralem, ab area sinistra majore ovato-oblonga, secernentibus. 



Long. 3^, diam. li mill. 



Habitat in vallibus Rungnu et Rimmau (alt. 4000 ped.) prope Dar- 

 jiling. DetexitW. XrBlanford. 



Although differing so much in form from Ennea vara, B., of 

 the Khasia Hills, this shell is nearly allied to it in the formation 

 and dentation of the aperture; the characters are, however, on 

 a more exaggerated scale. The Cape Pupa Layardi, B., in its 

 parietal and upper palatal plicae, approaches the structui*e ob- 

 servable in E. sienopi/lis, in which the plaits meet so closely 

 during their descent as to leave a scarcely visible line of separa- 

 tion, cutting off the sinus at the upper part of the dextral mar- 

 gin so completely as to present an analogy to the basal canal of 

 Cataulus. Like E. vara, the aperture is deficient in columellar 

 folds. The parietal callus is a modified representation of that 

 of the South Indian E. Pirriei, Pfr. 



Achatina Hastula, B. 



Testa turrito-subulata, tenui, oblique capillaceo-striata, fusco-cornea, 

 nitidula ; spira subulata, apice obtuse, sutura profundiuscula ; 

 anfractibus 9, primis convexis, postremis convexiusculis, ultimo 

 Y testae vix attingcnte ; apertura vix obliqua, ovato-elliptica, peri- 

 stomatis marginibus callo tenui junctis, dextrali recto acute, celu- 

 mellari arcuato callese albido, basi oblique truucata. 



Long. \2\, diam. Z\ mill. ; long, apert. 3| mill. 



Habitat ad Pankabari, prope Darjiling, rare. Teste W. T. Blanferd. 



Of a more slender form than the large Ach. tenuis-pira, B., the 

 whorls increasing very gradually, and not attenuate towards the 

 upper part of the spire as in that species. 



Achatina Orobia, B. 



Testa ovato-oblonga, solidiuscula, laevigata, leviter striata, striis non- 

 nuUis remetiuscuiis profunde inipressis sculpta, nitida, ojivaceo- 

 cornea ; spira convexe pyramidata, apice obtuso, sutura impressa; 

 anfractibus ^\-7\ convexiusculis, ad humerum angulatis, crenu- 

 latis, ultimo -3 testae supcrante ; apertura verticali semiovali, colu- 

 mella valde arcuata, callosa, basi oblique truncata, peristomate 

 recto, crassiusculo, obtuso. 



Long. 11, diam. h mill. ; apert. 4 mill, lenga, 3 lata. 



Habitat ad Sinchul et Darjiling (alt. ped. 8500 et 7000). Teste 

 W. T. Blanferd. 



Distinguished from the larger Khasia species, A. crassilubris, 

 B., by its peculiar sculpture, and by the formation of the whorls 

 below the suture.
