547, I neglected to state that while Hilgendorfi occurs at the top of 

 Mt. Ibuki, the var. tennis is found in a valley below. 



Trishoplita tosana var. anozona nov. 



Shell thin and glossy like tosana, and resembling that species in 

 shape and the size of the umbilicus, but differing from it in want- 

 ing a pale zone below the suture. It has a narrower umbilicus than 

 T. Hilgendorfi, var. tennis. 



Alt. 8J, diam. 13 mm. 



Alt. 7, diam. 11J mm. 



Akasaka, Mino (Mr. Y. Hirase, No. 7516). 



Still another form of this terrible genus, which I will call T. 

 tosana var. rufa, occurs at Kashima, Harima. It resembles ano- 

 zona, but is dull, russet-colored, densely striate spirally beneath, 

 subangular at the periphery in front. Whorls 5| to 5|, the spire 

 conic. 



Alt. 8, diam. 11| mm. 



Chloritis Hirasei n. sp. 



Shell openly umbilicate, depressed, thin and fragile, flattened 

 above, the earlier whorls a trifle sunken; pale brown. Surface 

 lustreless, densely beset with delicate hairs arranged in oblique 

 sweeps. Whorls 4J-, the last wide, rounded at the periphery and 

 beneath, hardly descending in front. Aperture lunate, the peri- 

 stome thin, a little, expanded, somewhat dilated at the columellar 

 insertion. 



Alt. 8J, greatest diam. 17-J-, width of umbilicus 2f mm. 



Kurozu, Prov. Kii (Mr. Y. Hirase, No. 786). 



This species is larger and flatter than G. fragilis Gude, with 

 more densely placed hairs, and a much wider umbilicus. C. osci- 

 tans v. Mart. , a form of which Mr. Hirase sends from Mikuriya, 

 Prov. Suruga, is a smaller, almost imperf orate species, the most 

 northern of its genus. No exact locality has hitherto been reported 

 for von Marten's species. C. eucharistus Pils., of Oshima, also 

 brought to light by Mr. Hirase, is the finest Chloritis of the 

 Japanese Empire, these four species being all known from Japan 

 to this time. 

 Ganesella tanegashimae var. dulcis n. var. 



Similar to the type except in color, the shell being of a very 

 dark and beautiful chestnut color, with a blackish peripheral
