282 ACHATINELLA LORATA. 



east and west of it sufficiently to be separated as a race, 

 A. I. nobilis. 



Kalihi. PL 52, figs. 5, 5a, and pi. 51, figs. 17, 18, coll. by 

 Gulick. The short ventrosa and longer pallida forms pre- 

 dominate. There are also pure white forms. The lip and 

 columella are white or nearly so. The same streaked or white 

 forms were taken by Mr. Spalding on the central ridge of 

 Kahauiki. 



Length 18, diam. 11.8, aperture 10 mm. (ventrosa pattern). 



Length 20.4, diam. 11.3, aperture 10 mm. (pallida pattern). 



On the east side of Kalihi Mr. Spalding found the shells 

 all small, length 15 to 17 mm. White, uniform or with a 

 streaked band, or chestnut-streaked on a yellow ground below 

 a white belt. 



In Mr. W. D. Wilder 's collection there are huge lorata from 

 Kalihi up to 25 mm. long. 



Moanalua. A large series in coll. C. M. Cooke shows the 

 short ventrosa form exactly as in Kalihi ; the same with colored 

 pattern remaining only in bands; and pure white, length 17 

 to 21 mm. These are from high lateral ridges, pi. 52, figs. 6. 



On the floor of the valley near the head on widely scattered 

 niu, Dr. Cooke found a small and usually more slender form, 

 length 15 to 19 mm., white, uniform or with a dark peripheral 

 band, sometimes a second one below it (pi. 50, figs. 7, 8). No 

 ventrosa occurred here. As in Kalihi shells, the aperture is 

 entirely white. 



There is also a series of this small race in the Thurston col- 

 lection, from the bottom of the north fork of Moanalua, 850 

 to 1300 ft. I suppose from the same colony where Dr. Cooke 

 collected. 



Halawa. A small series coll. by Gulick shows patterns sub- 

 stantially as in the ridges of Moanalua. 



Kalauao-Waimalu ridge. Mr. Spalding collected here speci- 

 mens of unusual color, Vandyke brown with lighter streaks, 

 some of them much smaller than the one figured, pi. 52, fig. 7. 



Waimano. A series from the Thaanum collection consists 

 of streaked shells like pi. 52, fig. 5, the cuticle largely lost, and 

 a white form; all solid shells of stout contour (pi. 50, fig. 6, 

 Waimano).
