lus, and a rugose texture to the surface of the shell, not usual in 

 specimens of Partulina from Oahu. PartuUna radiata is placed by 

 Pilsbry with Partulinas from the Island of Maui. In some collections 

 the shells are labeled Maui. However, radiata is typically an Oahu 

 shell and probably comes from the region of Nuuanu Valley. 



The lectotype (pi. 4, fig. 25) has the first embryonic whorl colored 

 terra cotta, next whorl upper half cartridge bufif, lower half shades 

 from terra cotta to pale vinaceous fawn and finally cartridge buff, 

 remainder of the embryonic whorls cream buff; the first half post- 

 embryonic whorl has the shell nacre worn off', remaining postem- 

 bryonic whorls pinkish buff, axially streaked with close-set lines of 

 hazel; lip and columella callus cartridge buff'. Length 17.8 mm., 

 greater diameter 12.0 mm., number of whorls 6. The surface of the 

 shell does not seem smooth but slightly rugose as compared with 

 A. a. glohosa, but this rugosity of the surface may be an illusion 

 caused by the axial streaking. 



From Arthur Blok I obtained a specimen (pi. i, fig. 16) which 

 greatly resembles the holotype of A. a. hanleyana in form and color 

 pattern. The postembryonic whorls ochraceous buff, axially streaked 

 with tawny, subperipheral band ochraceous buff ; the shell has a 

 rugose appearance ; impressed sutural band same as ground color of 

 the shell. Length 19. i mm., greater diameter 12.4 mm., spire height 

 9.9 mm. 



In the Thurston collection a sinistral shell (pi. 4, fig. 26) col- 

 lected by Dos Santos and reported from Kalihi has a ground color 

 that matches that of A. a. lianleyana. The main difference is that 

 the shell is heavily banded with dark bands. The postembryonic 

 whorls are warm buff axially streaked with ochraceous tawny and 

 banded with liver brown ; lip and columella callus pale vinaceous fawn. 

 This shell closely resembles the form of A. a. siniulans var. i on the 

 Kamanaiki-Kalihi Ridge. Probably it came from somewhere in the 

 Kalihi region at a similar elevation, possibly on the north side of the 

 valley. This sinistral shell may come from a colony of pure sinistral 

 hanleyana of which this is the dark color form. The dextral race is 

 probably from a colony of still lower elevation occurring directly 

 below the sinistrals.

A peculiar form of Achatinclla apcxfidva was procured from 

 Sowerby and Fulton in London. The shells were accompanied by no
