AMPHIDROMUS, GROUP XIX. 233 



flecks, or dark-streaked. Limbotto Lake ; two yellow specimens, alt. 

 40J and 34 mill., one with d-ark streaks. Coast of Paguat, west of 

 Gorontalo ; small, alt. 32 and 29 mill., uniform reddish. 



Var. fasciata Sarasin (pi. 68, fig. 26). Gorontalo. " Last whorl 

 very richly banded with chestnut brown, yellow, reddish and clear 

 green, the penultimate with two bands, passing into streaks above ; 

 peristome bluish, a dark margin behind it, passing into the chestnut 

 brown umbilical band ; alt. 33, diam. 14^ mill. A similar shell is 

 described by Kobelt from Minahassa (fig. 27, 28), this having the last 

 half whorl streaked, the rest of the shell banded, peristome dark as 

 in our specimen." It occurred among other forms of sinistralis. 



Tapparone-Canefri proposes the name var. decolor for a yellowish 

 white shell with transparent spots above. Fulton distinguishes a var. 

 rosea, " the same form as sinistralis, but of a pale rose-color, and 

 without the dark color inside aperture," and var. lutea, *' a fawn col- 

 ored variety with white interior." He credits the names of these 

 varieties to von Martens, who however did not name them, but 

 merely distinguished them by the letters C and B respectively. In 

 view of the wide range of individual variation in color demonstrated 

 by the Sarasins, the utility of naming these mutations is questionable. 

 Figs. 24, 25 represent a specimen received from Mr. Fulton as var. 

 rosea ; fig. 30 as var. lutea. 



P. bataviiz Grateloup. (PI. 65, fig. 34.) Shell reversed, ovate- 

 ventricose, imperforate, smooth, glossy, chestnut, obliquely banded. 

 Aperture subovate, the lip whitish, reflexed. Columella twisted 

 inward (intorta}.

Said to be decidedly lighter colored than Partula otaheitana Fer., 

 and ornamented with slightly oblique, longitudinal tawny flames, the 

 columella nearly straight and short, whorls 6. Alt. 30, diam. 18 

 mill. Said to be from Batavia, Java; but as many of the localities 

 given by Grateloup in the same paper are glaringly false, no great 

 dependence is to be placed upon this. 



A. KRUIJTI P. & F. Sarasin. PI. 68, figs. 18, 19, 20. 



Shell large, always sinistral, narrowly conic, with round, half- 

 covered umbilicus, solid. Whorls 7J, convex, separated by deep
