 The typical E. Luhuana is more depressed than the previous species, 

 hut it is less conical than most of the forms of E. peliomphala, from 

 which it may he readily separated, moreover, by the duller and coarser 

 periostracum, while the shells are also generally larger. The Hirado 

 specimens are all pale corneous : one has a dark -brown peripheral 

 band and a dark umbilicus ; a second specimen has, in addition to the 

 peripheral band, a lighter one below and a trace of a third above ; 

 two other specimens have three distinct pale bands, while the fifth 

 specimen has no bands. "With the exception of the first, they are all 

 without the dark patch in the umbilicus. All the Kioto specimens 

 have the dark umbilical patch, and one dark peripheral band. The 

 Tanabe specimens are all bandlcss, and, with one exception, all have 

 the dark umbilical patch. 



19. Eulota (Euhadra) peliomphala, Pfr. The only character 

 which appears of diagnostic value, so far as I am able to judge, is 

 that, whereas in E. Luhuana the periostracum is rough and dull, in 

 E. peliomphala it is smooth and more or less shining. The shells 

 of the latter are besides generally smaller, and the body-whorl is 

 usually more compressed. As regards shape, depression of spire, and 

 colour, this group presents a wide range of variation. In colour the 

 individuals vary from creamy white to dark brown. The bands also 

 vary ; for convenience the band formulae which we apply to Helix 

 nemoralis and H. hortensis may be used, the dark umbilical patch, 

 which frequently transgresses the angulation, representing the fifth 

 band. One specimen has the first and second bands confluent, and 

 the third separated from the fourth, which is broad, by a rather wide 

 space. The most common formula in typical E. peliomphala appears 

 to be 02345. Of the var. congener 50 per cent, have the formula 

 00345 ; 25 per cent. 00305 ; 6 per cent. 00045 ; 6 per cent. 00005 ; 

 while 1 per cent, are bandless.
