QANESELLA. 195 



Benson states that it approaelies the larger H. rapitmm, of the 

 hill region south of the (Tangetic angle ; but besides the absence 

 of the pecuHar colouring of that species, it is distinguished by its 

 more elongate and regular conical form and by the flatter base. 

 He continues, " I had affixed tlie MS. name of imeUula to this 

 shell in my report to Mr. Theobald; but on account of its 

 similarity to //. ;j?ff??rt of the late Mr. AV. J. Broderip, I have 

 deemed it advisable to adopt a more distinct and expressive 

 designation on publishing a description." 



The shell Benson had before him when describing the species 

 was much weathered, and he thought that the sculpture and colour 

 might eventually require an amended description. He referred to 

 a fault rufous tint, not to be detected elsewhere, towards the 

 termination of the keel. A specimen in my collection, with the 

 periostracum in excellent condition, enables me to confirm this and 

 to supplement the description in this respect. The shell is whitish 

 corneous and the keel has a narrow rufous border above and below ; 

 this can be traced a long way up the spire. 



Dautzenberg and Fischer * unite with the present species a shell 

 from Tonkin ])reviously described by them as Satsuma lantenoisi. 

 Another form from Perak, described by Crosse as Helix {Geotrcchus) 

 jieralensis, they consider merely a variety of G. acn's.
