gude: HELICOID LAND-SHELLS FROM JArAN & THE LOO-CHOO IS. 197 



51. Eulota (Euhadra) mercatoria, Gray ; var. atrata, Pils- 

 Kunchan ?, Loo-Choo. Three specimens. Diam. niaj. 52, min. 

 43-5 ruin.; alt. 36 mm. Diam. maj. 49-5, min. 42 mm.; alt. 39 mm. 

 Diam. maj. 51, min. 46 mm. ; alt. 42 mm. 



52. Ktjlota (Euhadra) Largillierti, Phil. Shimari (?), Loo-Choo. 

 Eight specimens. More elevated in the spire than the shells figured 

 by Mr. Pilsbry in " Marine Mollusks of Japan." One specimen belongs 

 to the var. immaculata, Ad. & Eve. Pive, having two bands, one 

 above and one below the periphery, are referable to the var. eucosmia, 

 Pils. One of these has pale fuscous bands on a greenish yellow 

 ground, while in another the bands are very broad, and almost black ; 

 the third and fourth specimens have the bands very narrow, chestnut 

 on a pale buff ground ; the fifth approaches the var. zacosmia, Pils., in 

 having the bands separated by a whitish zone. The latter variety is 

 represented by a single specimen, but the ground colour is much paler 

 than in Mr. Pilsbry's figure. The colouring of this species and its 

 varieties resembles that of some Helicostyla, with their peculiar lustre- 

 less hydrophanous cuticle. 



53. Eulota (Euhadra) Yaetamensis, Pils. Yaeyama, Loo-Choo. 

 One specimen. Brown, with a dark chestnut peripheral band on 

 a lighter zone; lip brown. Diam. maj. 26, min. 23 - 5 mm. ; alt. 

 14 mm.
