Eadula with 81 rows of teeth, arranged : 



48 . 1 . 10 . 1 . 10 . 1 . 48 

 59 . 1 . 59 



The centre tricuspid, admedian with cusp on outer side ; laterals 

 bicuspid, with points even. 



The male organ is a modified form of that of E. binoyaensis ; 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. liypliasma, but in 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 lower part of e#ch whorl, where it is reddish, and 

 on the last whorl there is a chestnut band above and below the 

 keel, which is itself white. According to Jousseaume, specimens 

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

 throughout. 



Major 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.
