Species of Amphidromus, Albers. 79 



and two pale yellow bands on the last whorl, the topmost 

 yellow band being continued above ; Up and columella pink. 



A. suspectus, var. albolabiata, Fulton. (PI. VI. fig. 9.) 



Loc. Timor. 



Differs from suspectus in being larger, in having a xoliite 

 Up and columella, and only two dark brown bands on last 

 whorl, the upper being continued at the suture of the upper 

 whorls. 



28. A. bataviie, Grateloup. 



= Partula latavia, Grat. Actes Bordeaux, xi. p. 425, pi. ii. fig. 12. 



Loc. Batavia, Java. 



I do not know this species or where the type may be ; 

 but, judging from the description and poor figure, I should 

 think it is allied to filozonatus. 



29. A. porcellanus, Mousson, Moll. Java, 1849, p. 33, 

 pi. iii. fig. 4. 



Loc. Java. 



A well-known and distinct species. 



A. porcellanus, var. xiengensis, Morlet, Journ. de Con. 1891, 

 pp. 27 and 240, pi. v. fig. 4. 



Loc. Laos. 



Like porcellanus in form, but thicker and generally larger. 

 Coloration agrees with porcellanus, except that the oblique 

 stripes are interrupted by two or three narrow spiral bands 

 besides the central one. 



30. A. columellaris, Mollendorff, Nach. mal. Gesell. 1892, 



p. 98, pi. i. fig. 9. 



Loc. Sierah Island, Tenimber Islands. 



A very beautiful species which varies considerably in colo- 

 ration, but easily separated from its allies by its slender form 

 and constricted aperture. I have some light-coloured speci- 

 mens without the narrow red band at suture under the 

 manuscript varietal name of gloriosa, Bttg. 



Group of A. sylheticus. 



31. A, sylheticus, Reeve, Con. Icon. 1849, Bui. fig. 564. 

 = lepidus, Gould, Proc. Bost. Soc. 1856, vol. vi. p. 12. 



Loc. Sylhet Hills ; Khasi and Garo Hills.
