The shell here represented proves to be a variety of 
A. striatella, a species varying much in growth, but always 
well characterized by its delicate close-set rib-like strise.

Benson, MSS. 
Hub. Howrah, near Calcutta. 
For this species I am indebted to Mr. Benson, who 
relates haring taken three specimens alive in 1835, from 
beneath a fallen palm tree at Howrah, near Calcutta ; and 
he is not aware that it has been collected since.

arcuata, abrupte truncatd; pellucido-lacted, strigis cas- 
taneis perpaucis angustis ornatd. 
The arched Achatina. Shell subulate, whorls eight 
in number, flattened, smooth, polished, engraved 
with rather distant fine impressed longitudinal strise,

Helix octona, Chemnitz. 
Bulimus oc tonus, Lamarck. 
Hab. West Indies, South America, Pacific Islands. 
This species, for which others have frequently been 
mistaken, may be distinguished by its delicate shining 
surface and very transparent texture ; the sutures of the 
spire are also peculiarly impressed, giving a globose form to 
the whorls, It has a very-wide range of habitation, and 
is composed sometimes of eight, sometimes of ten whorls.

Achatina Cassiaca. Achat, testa elongato-subulald, apice 
subpapillari, anfractibus quatuordechn ad quindecwi,
