brown. Foot above and below veiy dark brown, the sides 

 studded with large patches of darker hue, the posterior por- 

 tion tinged with red. The head above and tentacles covered 

 with almost black granulations " (Baldwin).

This species stands close to small forms of A. magna. It is 

 smoother, of a brighter yellow color under the cuticle, which 

 is more persistent. The last whorl is more regularly ellip- 

 tical than usual in magna. The description and figures 13 

 and 14 are from cotypes received from Mr. Baldwin. 



The cuticle is typically dense and dark on the last whorl. 



In some specimens (no. 2232 coll. C. M. Cooke) the cuticle 

 is much worn. In others it is closely mottled on the penulti- 

 mate and front of last whorl. Probably intergraddng forms 

 with A. grayana will be found.

Shell imperforate, dextral, ovate-conic, rather solid, some- 

 what shining, grayish-flesh colored, variously marked with 

 chestnut bands disappearing above. Spire inflated- conic, the 

 apex acute, black; whorls 6%, the upper ones flat, radially 

 plicate, the penultimate convex, last whorl nearly as long as 

 the spire, lightly striate. Aperture subvertieal, acuminate- 

 oval. Columellar fold median, subtransverse, triangular; 

 peristome simple, unexpanded, the columellar margin slightly 

 ^dilated, adnate. Length 21.5, diam. 12 mm. Sandwich Is.,

It has been recorded from Oahu, evidently in error, since 

 no Oahuan species has flat, radially plicate upper whorls. 

 Two specimens in the C. M. Cooke collection, received from 

 D. D. Baldwin are figured. In these shells (pi. 39, figs. 2, 

 3), which are not localized nearer than " Lanai," the cuticle 

 is olivaceous yellow marked with darker or reddish-brown
