12 KEWCOMBIA. 



comb at about the same time almost sixty years ago the color 

 of the last whorl is a rich cinnamon, between raw sienna and 

 ochraceous (of Ridgway's " Nomenclature of Colors''), fading 

 upwards, and darker at the base (pi. 3, figs. 8, 9). This was 

 evidently the coloration of Pfeiffer's type. Some of the 

 Mapulehu shells are of this color, others being darker, as in 

 those from Moanui. 



At Moanui (pi. 14, fig. 1) the base of the last whorl is burnt 

 umber, the upper part drab or olive, the transition often abrupt 

 at the periphery. Frequently there are numerous umber bands 

 occupying half the space between periphery and suture. The 

 size is greater than at other localities up to length 23^, diam. 

 8J-, and length 24, diam. 8 mm. 



At Ahaino and Kupeke (pi. 14, figs. 2, 3, 4) the shells are 

 small, the microscopic granulo-striation well developed, other 

 sculpture obsolete. The last whorl is ochraceous with several 

 umber bands and basal tract, or olive with an umber base. 

 The largest shells are 18 mm. long, 6 wide, most being between 

 16 and 17 mm. long. This local race may be called var. 

 decorata. 



Specimens from Honomuni (pi. 14, figs. 6, 7) are very much 

 lengthened, ochraceous, base a little darker, spire worn, dull 

 violet or purple. Columellar reflection very small, adnate; a 

 "false umbilicus" visible in basal view. Length 19, diam. 6 

 mm., whorls 6. This form may be called var. honomuniensis. 



8a. N. c. UALAPUENSIS n. subsp. PI. 2, figs. 11, 12. 



Similar to N. cumingi in having well-developed spiral cords, 

 but the surface between and over them is minutely but strongly 

 puckered or wrinkled longitudinally (fig. 12), and not spirally 

 striolate as in cumingi and cinnamomea. 



Molokai: Ualapue (D. Thaanum), no. 94490 A. N. S. P.; 

 Kahaanui (Thaanum). 



The upper whorls are considerably eroded in the type lot, but 

 the younger individuals show the striped pattern of cumingi. 

 It is a little smaller than N. cumingi, length of figured type 20, 

 diam. 6^ mm. 



This race seems about equally related to cumingi and cinna- 

 momea, with incipient characters of pfeifferi.
