The male organ is a modified form of that of E. hinoyaensis ; the 

 loop is not present, the muscular caecum is longer, the amatorial 

 organ is present, and the spermatophore is of the same type.]

Very near E. hypliasma^ but iu typical shells the spire is higher, 

 the sides meeting at a more acute angle, the sculpture is finer and 

 the coloration different. The shell is whitish or brownish horny, 

 except on the lo^v■e^ ])art of each whorl, where it is reddish, and 

 on the last A\"horl there is a chestnut band above and beloM- the 

 keel, \Aiiich is itself white. According to Jousseaume, specimens 

 occur with the keel also reddish, and some are chestnut-browu 

 throughout. 



lAlajor diam. 11, min. 10, axis 9 mm. The height of the axis 

 differs from Adams's measurements, but is taken from the shell 

 believed to be the type now in the British Museum.
