Dr. Cooke, who examined the type, thought this a sinistral 

 individual of A. pulcherrima. ' * Newcomb suggested that this 

 might be only a form of A. sordida ; it appears however to b& 

 distinct, being broader, brown in general coloration, and hav- 

 ing a brown in place of a white lip. It is a little doubtful 

 from its form if it be correctly placed in this group [Acha- 

 tinella s. sir.], but the sections are very artificial " (Sykes, 

 Fauna Hawaiiensis, p. 304). As I have not seen the shell, I 

 cannot properly express an opinion; but from the figure it 

 seems as near the torrida form of decipiens from the Kaaawa- 

 Hakipuu ridge as anything, and I put it here for want of a 

 better place. It may be noted that several enigmas of Frick- 

 Pfeiffer origin were from the Koolauloa district. We know 

 very little about Frick, but from what he got we may infer 

 that the country between Kaneohe Bay and Kahuku was one 

 of his collecting grounds.

Bather large, compact, capacious shells, smooth, never 

 streaked with green, usually banded. This series comprises 

 numerous forms on both sides of the western half of the Main 

 Range. 



8. A. ROSEA Swainson. H. 34, figs. 1 to 8&. 



1 1 Shell reversed, pale rose-color, with obsolete white bands. 

 I place this, for the present, as a variety of the last [A. buli- 

 moides] to which, except in being reversed, it bears a close 

 resemblance in size, form and general habit. It is entirely 

 of a pale and delicate rose-color, with two obsolete bands of 

 white on the body-whorl. The margin of the lip and columella 

 are of a deeper rose-color, and the aperture white. It should
