60 PARTULINA, MAUI. 



30a. Var. kaupakaluana n. v., pi. 13, fig. 16, has the last 2 

 whorls closely streaked with ochraceous or olive-buff on a 

 whitish ground, a white belt on the base. It is known to us 

 by two examples, not quite mature, from Kaupakalua, no. 2101 

 coll. C. M. Cooke. 



31. P. DOLEI (Baldwin). PI. 12, figs. 15 to 18. 



Shell sinistral, perforate, acutely pyramidal, thin but strong, 

 glossy, white with a dark chestnut band below the periphery, 

 and usually several lines and obliquely-streaked bands of light 

 brown in the peripheral region. Surface polished, delicately 

 marked with growth-striae and almost effaced spiral lines. Spire 

 straightly pyramidal, rather acute, the apex white. Post- 

 embryonic whorls decidedly convex, the last swollen below the 

 suture, then somewhat compressed; suture deep, narrowly mar- 

 gined. The aperture is oblique, white within, with a rib within 

 the lip, which expands somewhat. Columellar fold strong and 

 oblique. 



Length 24 J, diam. 14 mm. ; 6f whorls. 



Length 25, diam. 15 mm. 



Length 25J, diam. 14 mm. 



''Animal when extended in motion longer than the shell. 

 Mantle intensely black with a broad outer margin of yellow and 

 a conspicuous orange spot in the center of the margin. Foot 

 tapering behind, above and below light yellow. Tentacles long 

 and slender, light slate. Head above lightly granulated"

The dark band below the periphery is a constant feature, and 

 rarely no other markings are present. When lighter bands are 

 developed they may ascend the spire above the suture, or they 

 may be confined to the last whorl. The embryonic shell (pi. 

 15, fig. 18) is acutely angular and has a subperipheral band. 

 The columella is convex. It is closely related to P. nivea but
