anfractibus octo, longitudinaliter creberrime plicato- 
striatis, ad suturas cremlatis, columella subcontortd, 
conspicue truncata ; pellucido-fuscescente, strigis cas-

Achatina dactylus. , Broderip. 
Hal. Tumaco, West Coast of South America. 
Dr. Pfeiffer refers this shell to the Buccimm striatum of 
-Muller, hut there is no mention of the characteristic striped 
painting in the description of that author; neither is 
there any account of the delicate tinge of yellow or rose 
colouring which characterizes the species referred to it by 
M. Deshayes, namely, the Achatina rosea. There is no 
doubt, however, of the shell under consideration being 
identical with that figured by Chemnitz under the head of 
B. striatum in Conch. Cab. vol. ix. pi. 120. f. 1030. 
Species 26. (Pig. a aud b, Mus. Cuming.) 
Achatina Sowerbyana. Achat, testa ovato-fusiformi, 
tenuicutd, subventricosa, anfractibus sex ad seplem, 
undigue pulckerrimb granoso-decussalis, ad suturas 
crenulatis, columella valde arcuata, leviier contortd, 
conspicue truncata; diaphano-fuscescente, nitente, 
strigis longitudinalibus castaneis angustis frequentibus 
irregulariter picta. 
Sowerby’s Achatina. Shell ovately fusiform, somewhat 
thin, rather ventricose, whorls six to seven in

arched, slightly twisted, conspicuously truncated ; 
bright transparent brown, shining, irregularly painted 
with frequent narrow chesnut streaks.

A fine large delicately bright transparent species of 
the Glandina section of the genus, prettily granulated

Species 27. (Mus. Dennison.) 
Achatina lignaria. Achat, testa oblongo-cylindracea, 
anfractibus octo, granulis oblongis undique exsculptis, 
ad suturas rude cremlatis, columella abrupte truncata, 
aperturd parviuscula; fuscescente-spadiced, strigis 
angustis saturatioribus subobscurb et irregulariter no- 
tatd.

Hab. ? 
This fine species from the collection of J. Dennison, Esq., 
approaches nearer to A. Sowerbyana than to any hitherto 
described. 
February, 1849.
