Hab. Kolau, Oahu. 
Shell dextral, conical ; whorls 6, rounded, margined above, the last 
somewhat inflated ; suture well-impressed ; columella white or brown- 
ish, terminating in a twisted plait ; aperture ovate, white ; lip simple, 
thickened within ; strize longitudinal, fine ; colour of shell green or 
brown on the last whorl, above white, with fine longitudinal veins of 
the colour of the epidermis. 
This species seems to be intermediate between 4. producta, Reeve, 
and A. venulata. 
53. ACHATINELLA assimILts (Pl. XXIII. fig. 53). A. testa co- 
nico-elongata, superne acuta ; anfractibus 7, rotundis ; sutura bene 
impressa; apertura parva, ovata; columella brevissima, plicata, con- 
torta; labro acuto, interne subincrassato ; colore albo vel rubro- 
flavido, anfractus ultimi dimidio inferiori interdum albido ; interne 
albo-niveo.

Hab. W. Mani. 
Shell conically elongate, acute above ; whorls 7, rounded; suture 
well-impressed ; aperture small, ovate ; columella very short, plicate, 
twisted ; lip acute, thickened slightly within ; colour white or salmon, 
sometimes the lower half of the last whorl white, and the rest of sal- 
mon; within pure white. 
This species might be mistaken for a dwarf variety of A. Mastersi. 
Its habits are quite different, its locality distant, and the shell has an 
aspect quite distinct from the small varieties of 4. Mastersi, as found 
on W. Mani. 
54. ACHATINELLA RETICULATA (Pl. XXIV. fig. 54). A. testa co- 
nico-ovata; anfractibus 6, perrotundis ; sutura superne mediocri, 
supra anfr. ultimum profunda; apertura parva, ovata; colu- 
mella brevi cum dente plicato, fere transverse ; colore fusco vel 
castaneo cum lineis et notis transversis, albidis, figuras varias 
epidermide imponentibus, speciem texti spiculati vel operis acupicti 
prebentibus.
