32 PARTULINA, MOLOKAI. 



11. P. PROXIMA (Pease). PL 9, figs. 1 to 9. 



Shell sinistral, imperf orate, oblong-ovate, ventricose; rather 

 solid; finely striated transversely, striae somewhat flexuous, 

 granulose and interrupted, more regular and conspicuous be- 

 neath the sutures. Whorls 6, convex, marginated, the last 

 being somewhat produced obliquely and flattened on the middle, 

 so as to give in some specimens a subangulated appearance at 

 the base. Aperture somewhat oblique, of an oblong-ovate 

 form; columellar fold strong. Color chestnut-brown, striped 

 and mottled irregularly with darker brown and white; columella 

 and inner edge of aperture purplish red (Pease).

"The above species from the island of Molokai appears to 

 represent the H. marmoratus and its varieties of the island of 

 Maui. It is, however, larger and heavier; the last whorl has 

 also a peculiar shape, in common with that of several of the 

 larger species found on Molokai. All the specimens I have 

 seen are sinistral, and the columella and edge of the aperture of 

 a deep red " (Pease). 



The first 1^ whorls are white; then very obliquely protractive 

 brown stripes appear, continuing to the end of the embryonic 

 stage, which comprises 3J whorls. The succeeding neanic stage 

 has stripes in general parallel to the growth-lines, but more or 

 less interrupted or irregular. This pattern may continue to and 

 upon the last whorl (figs. 1, 5) ; or the stripes may become 

 nebulous or reduced on the last two whorls. The ground-color 

 varies from glossy white to strongly brown tinted, or the last 

 whorl may be brown tinted towards the base, white above. In 

 some shells the stripes are very obliquely retractive on the later 

 whorls (fig. 2). 



In another variety the stripes are tawny yellow on a white or 

 slightly coffee-tinted ground. The sutural margination is dis-
