It is doubtful just where to place this shell. From the plate 

 it is a dextral shell of about the size of A. bella Rve., and may be 

 related to the yellowish forms of that shell. Dr. Cooke found the 

 shell in the British Museum under this name, to be in shape like 

 a small virgulata. The fourth and fifth whorls are of a dull yellow- 

 ish brown color, with numerous bands of a slightly darker shade 

 on the fifth whorl.

A. oiissa Xewc. V. Zool. Soc. London, i->53. p. 155. pi. xxiv, fig. 71. 



Shell dextral, conical, solid, pointed at the apex ; last whorl 

 ventricose ; .striae decussating; whorls 6, rounded ; suture moder- 

 ate; aperture subovate ; columella short, terminating in a very 

 strong plait ; lip white, broadly expanded and subreflected ; um- 

 bilicus open ; colour dark chestnut sprinkled with white, with 

 a white subcentral band on the la.st whorl. Long. 16/20, lat. 

 10/20 poll. 



This shell in form approaches the genus Partula. Having 

 obtained the specimens alive, I have been enabled to examine the 

 animal, and can find no marks to distinguish it from the common 

 type of the genus Achatinella. — Newc.
