The form of this shell is peculiar, and there is something 
equally characteristic in the marking.

Achatinella Byronii , Gray. 
Hab. Sandwich Islands. 
Although the black sutural line is striking and con- 
stant, the character is by no means confined to this species. 
Two or three have been confounded together in collections 
under this apprehension. 
Species 24. (Mus. Cuming.) 
Achatinella castanea. Achat, testa oblongo-conicd, 
sinistrorsd, apice subobtusd, anfractibus convexis, su- 
perne tenuimarginatis, columella dentato-plicatd ; ustu- 
lato-luted, anfracliis ultimi dimidio inferiori vivide 
castaneo, inlerdum undique castanea, columelld et aper- 
turee fauce albis. 
The chestnut Achatinella. Shell oblong-conical, 
sinistral, rather obtuse at the apex, whorls convex, 
thinly margined round the upper part, columella den- 
tately plicate ; burnt yellow, lower half of the last 
whorl bright chestnut, sometimes chestnut through- 
out, columella and interior of the aperture white. 
Hab. Sandwich Islands. 
The colouring of this species always partakes more or 
less of rich bright chestnut.
