figures the animal of Blanfordia japonica on plate 7 as figure 12, and 

 Blanfordia bcnsoni on plate 7, figure 11. 



In 1876 Pfeififer (3, p. 22) lists Blanfordia japonica and Blanfordia 

 bcnsanl and also other species which do not belong in this genus. 



In 1878 Nevill (4. p. 254) fixed the tyi)e of Blanfordia by designat- 

 ing Blanfordia hensoni as type species. 



A long interval passed before reference is again made to this genus. 

 In 1897 von Mollendorff (11, p. 32) redescribed Blanfordia hensoni 

 A. Adams from material collected by 15. Schmacker near the city 

 of Hakodate, Jeso, Japan. 



In 1900 Dr. PiLsbry (13, p. 12) renamed Blanfordia hensoni, call- 

 ing it Poniatiopsis hirasei, which l)ecomes a synonym of Blanfordia 

 beftsoni. 



In the same year (1900) von Mollendorff (12), after referring 

 to his former treatise on Blanfordia hensoni, described Blanfordia 

 japonica, which he states was collected l)y Ilirase on Sado. /. e., the 

 type locality. 



Pilsbry (14), in 1901, in his " Notes on tlie Recent Literature of 

 Japanese Land-Snails ", places his Poniatiopsis hirasei in the sy- 

 nonymy of Blanfordia hensoni Adams, and bestows the name Blan- 

 fordia hensoni var. minor upon the moUusk described under the 

 name Blanfordia japonica by von MoUendorfif. With this dictum 

 I do not agree, but hold that von Mollendorff was correct. 



The following year Pilsbry (15, pp. 26-27) again discussed Blan- 

 fordia japonica and Blanfordia hensoni and described Blanfordia 

 japonica var. simplex as new from Nishigo, L'zen (Honshu Id.). 



In 1903 Pilsbry (16, p. 114) again refers to Blanfordia japonica 

 from Sado Island, and raises his subspecies Blanfordia japonica var. 

 simplex to specific rank. 



For 12 years no papers a])pear in the malacological press, but in 

 1915 Dr. I'ilsbry (23) again reviews "The Japanese Species of 

 Blanfordia " and wrongly places Katayama nosophora in this genus. 

 He again lists Blanfordia japonica, Blanfordia hensoni, and Blan- 

 fordia simplex and with them Blanfordia nosophora and figures all 

 four and gives a key to them. 



Here, too, he wrongly designates Blanfordia japonica as type of 

 the genus Blanfordi-a, this having been established by Xevill in 1878 

 to be Blanfordia hensoni A. Adams. 



Nine years later, 1924, Pilsbry (30) adds another species, Blan- 

 fordia Integra, from Makuragisan, IzAuno (Honshu Id.) to this 

 genus. Here also he establishes the subgenus Vicina, with Poniatiop- 

 sis hirasei as type, which he says is apparently .synonymous with
