back of the canal; height of shell 9; of last whorl, 6; of aperture, 4; 

 diameter, 3.5 mm. U. S. Nat. Mus. Cat. No. 219671. 



Type-locality — Salina Cruz, Mexico; C. R. Orcutt. 



It is quite probable that a series would show v^ariations of color. 



ALIA CALLIMORPHA, new species. 



Shell small, yellowish, with brown mottlings under a thin brownish 

 periostracum, with about five whorls; including a small smooth 

 nucleus; suture obscure, whorls only slightly convex on the spire; 

 surface smooth except for a few spiral striae on the canal; aperture 

 narrow, with a rather wide commissure at the posterior junction of 

 the lip and body; outer lip slightly thickened, with four or five 

 denticles on the inner face; body polished, pillar short; canal short 

 and wide; height of shell 5; of last whorl, 3.5; diameter, 2.5 mm. 

 U. S. Nat. Mus. Cat. No. 271491. 



Type-locality. — San Diego, California, C. R. Orcutt. 



This belongs with the group of A.- californiana, from which it 

 diffei-s by its much smaller size, relatively more slender form, and less 

 pronounced coloration. 



ALIA XENIA, new species. 



Shell large for the genus, acute, waxen white, with abundant 

 reddish brown painting — clouds, streaks, or occellations — with about 

 nine rather flat-sided whorls, exclusive of a swollen smooth nucleus 

 of about one whorl more; suture distinct, not appressed; surface 

 smooth and polished, except for half a dozen spiral grooves on the 

 canal; aperture narrow, the outer hp thickened with a shght varical 

 swelhng behind it; internally adults have about eight denticulations ; 

 body enameled, pillar also with a few obscure nodulations; canal 

 short, slightly recurved; height of shell, 18; of last whorl, 10; diam- 

 eter, 6 mm. U. S. Nat. Mus. Cat. No. 59370. 



Type-locality. — Cape San Lucas; W. H. Dall. 



This species is more nearly related by its shell characters to Aus- 

 trahan species like GolumbeUa intexta Gaskoin than to the usual West 

 American types. 



ALIA CASCIANA, new species. 



Shell small, yellowish, acute, with a three-whorled smooth nucleus 

 beginning with a very minute apex and five flattish subsequent whorls; 

 suture distinct, minutely channeled; axial sculpture of faint incre- 

 mental fines; spiral sculpture of very faint striae on the whorls 

 behind the periphery, and a few stronger grooves near and on the 

 canal; base subangular at the periphery, flattened in front; aperture 

 narrow, simple, body sfightly glazed, pillar short with a strong keel 

 at its anterior border; canal short, deep,; height of shell, 9; of last 

 whorl, 6; of aperture, 3.5; diameter, 4 mm. U. S. Nat. Mus. Cat. 

 No. 209456.
