or other Zonitoids; moreover there is no trace of a caudal pore. Under thèse circumstances, 

 I hâve provisionnally located the genus at the end of the Helicidae, without being convinced 

 that this is its permanent restingplace, as I hâve no sufficient materials and expérience, for 

 a satisfying décision.

One young spécimen has been collected, its length (in alcohol) is only about 1 1 mill., 

 being much less thans a third part of the length recorded by CANEFRI (38 mill.) or COLLINGE 

 (36.5) but the narrow footsole is in accordance with the figures of the latter author, The 

 sides of the body are more convex than in his fig. 6 and I can not detect any traces of 

 black spots on the notum; as to the latter point, I may observe, that Canefri in his 

 description, mentions: „inferne pallido, immaculato" ; the more convex sides may be caused 

 by contraction in alcohol.

The majority of the spécimens collected by Dr. KOCH has a more acute spire than in the 

 figure of Canefri (1. c.) but some of them are equally blunt. The yellow colour of the aperture 

 is in some spécimens less intensive, (not only on account of youth) in a few even wanting ; 

 under the lens I see often some spiral striae, but this seems to be of little importance, other- 

 wise the spécimens agrée as well as may be desired, with the description and figure of the author.

The spécimens are not adult, but recognizable by the sculpture and banded colour- 

 pattern, though both characters are not very conspicuous, partly by the action of formalin.
