The elegant zigzag painting of this species is very 
similar to that of A. venusta.

cylindraced, solidiuscida, dextrorsa, spied brevi, apice

This and the following species belong to the same 
peculiar type as A. cent ulus of the preceding plate. 
Species 38. (Mus. Cuming.) 
Achatinella straminea. Achat, testa acuminato-ob- 
longd, sinistrorsa, anfractibus concexis, oblique striatis,

oblong, sinistral, whorls convex, obliquely striated, 
coiumella strongly twisted-plaited ; straw-coloured, 
unspotted.

This species is of a peculiar light straw-colour, and 
differs essentially in form from any of the preceding. 
Species 39. (Mus. Cuming.) 
Achatinella nucleola. Achat, testa abbreviato-ovata, 
subglobosd, dextrorsa, spied breviuscula, anfractibus con-

The kernel Achatinella. Shell shortly ovate, some- 
what globose, dextral, spire rather short, whorls con- 
vex, finely striated, crenulated at the sutures, colu- 
mella arched, with a twisted plait ; reddish-chestnut. 
Gould, Pro. Boston Nat. Hist. Soc. 1845, p. 28. 
Achatinella brevis, Pfeiffer. 
Hab. Sandwich Islands. 
Very closely allied to A. ventulus, but sufficiently dis- 
tinguished by its more globose form, lighter red-brown 
colour, and more prominent abruptly truncated columeEa. 
Species 40. (Mus. Cuming.) 
Achatinella Mighelsiana. Achat, testa acuminato- 
conicd, dextrorsa, anfractibus rotundatis, super ne obso- 
lete marginatis, columella valde contorto-plicata ; opaco-

Pfeiffer, Pro. Zool. Soc. 1847, p. 231. 
Hab. Molokai, Sandwich Islands. 
Each example of this species in Mr. Cu min g’s coEectiou 
is encircled round the lower part of the whorls by a dark 
line, which is concealed in aE but the last, by the convolu- 
tion of one whorl upon the other.
