Hab. St. Helena ; Lieut. Lefroy. 
Of a very distinct type from any other species of the 
genus. 
Species 80. (Mus. Benson.) 
Achatina Jerdoni. Acliat. testa subpyramidali-oblongd, 
anfractibus septem ad octo, convexis, lavibus, politis, 
ad suturas suhtiliter marginatis , columella arcuatd, 
conspicue truncata, aperturd parvd ; fusco-corned.

long, whoi'ls seven to eight in number, convex, 
smooth, polished, finely margined at the sutures, 
columella arched, conspicuously truncated, aperture 
small ; brown horny. 
Benson, MS. 
Hab. Nilgherries, Hiudoostan ; Jerdon. 
A polished horny species, of rather narrow, pyramidal 
growth. 
Species 81. (Mus. Benson.) 
Achatina crassilabiiis. Acliat. testa subpyramidali- 
conicd, basin versus ventricosd, anfractibus octo, subro- 
tundatis, ad suturas crennlatis, crenulis numerosis, 
confertis, in striis impressis descendentihus, columella, 
profunde arcuatd, conspicue truncata, aperturd par- 
viusculd, labro subincrassato ; corneo-fusca. 
The thick-lip Achatina. Shell somewhat pyramidally 
conical, ventricose towards the base, whorls eight in 
number, rather rouuded, crenulated at the sutures, 
crenules numerous, close-set, descending in impressed 
striae, columella deeply arched, conspicuously trun- 
cated, aperture rather small, lip slightly thickened ;

Benson, Journ. Asiat. Soc. 1836, vol. v. p. 353. 
Hab. North-east Frontier of Bengal ; Benson. 
Distinguished by its rounded, conical form, finely im- 
pressed crenulated sculpture, and slightly thickened lip. 
Species 87. (Mus. Benson.) 
Achatina Nilagarica. Achat, testa pyramidali-turritd, 
anfractibus decern, convexis, ad suturas subtilissime 
crenulatis, delude striatis, columella subprofunde ar- 
cuatd, aperturd parvd ; fusco-corned. 
The Nilgherry Achatina. Shell pyramidally turreted, 
whorls ten in number, convex, very finely crenulated 
at the sutures, then striated, columella rather deeply 
arched, aperture small; brown-horny. 
Benson, MS. 
Hab. Nilgherries, Hindoostan; Jerdon. 
Allied to the preceding species in detail of character, 
but amply distinguished by its more elongated pyramidal 
form. 
Species 88. (Mus. Cuming.) 
Achatina Lindoni. Achat, testa cylindraceo-oblonga, 
utrinque attenuatd, soliduld, anfractibus octo, planula- 
tis, laevigatis, lineis curvatis increment! leviter im- 
pressis, ad suturas marginatis, duobus ultimis oblique 
descendentihus, columella basi arcuatd, supra gibbosd, 
aperturd angustd, supeme sinuatd; fulvo-cornea, po- 
litd, strigis castaneis arcuatis obscure tinctd. 
Lindon’s Achatina. Shell cylindrically oblong, at- 
tenuated at each end, rather solid, whorls eight in 
number, rather flattened, smooth, slightly impressed 
with curved lines of growth, margined at the sutures, 
the last two whorls descending obliquely, columella 
arched, gibbous above, aperture narrow, sinuated at
