Swainson's figures agree exactly with my pi. 33, figs. 1&, 

 Id, from " Kawailoa," which I take to toe the type locality. 

 It ' ' has now become a very rare shell, ' ' owing to the destruc- 

 tion of forest, but I imagine that it will be found higher up, 

 in the region between Kawailoa, Waimea and Kaipapau. 



A. bulimoides is always dextral, imperf orate or nearly so, 

 solid; the upper whorls are finely striate spirally and flesh- 

 dinted ; the lip is well thickened within and usually white or 

 yellowish, but brown in dark forms. There is never a sub- 

 sutural dark line as in brown-band forms of A. rosea, but the 

 suture is often bordered with an impressed line. 



Specimens from Kawailoa measure: 



Length 20.6, diam. 12.4, aperture 11 mm. ; whorls 5%. 



Length 21.3, diam. 11.8, aperture 11 mm. ; whorls 6%. 



In a lot of 48 from " Kawailoa " (pi. 33, figs. 1 to lj, Gu- 

 lick coll., 92489, A. N. S. P) , the following color-forms occur : 



1. White, the upper whorls pale-pink or flesh-tinted ; peri- 

 stome yellowish; suture usually margined (fig. 1), 6 speci- 

 mens. la. Similar, but having a brown streak behind the 

 outer lip, 5 specimens. 



2. White with two chestnut bands bordering a peripheral 

 white belt, upper whorls fleshy, lip white or brownish (figs. 

 la, & ) ; 6 specimens. 



2a. Similar but the peripheral belt and base tawny ; a white 

 umbilical patch or none (fig. le) ; 5 specimens. 



3. Entire base purple-brown, a brown band above the 

 peripheral white band; spire sometimes dark (fig. Id) ; 9 spe- 

 cimens. 



4. A white zone below the suture, elsewhere chestnut or 

 purplish-brown, lip often brown (fig. lc/) ; 14 specimens. 



5. Purplish-brown with fleshy suture and summit (fig. It) ; 

 2 specimens. 



6. Base whitish, upper part purplish-brown (fig. l/i) ; one 

 specimen. 



7. Basal patch and peripheral band dark chestnut, a light 

 chestnut zone above (fig. le).
