While the young of L. solida cubensis are indistinguish- 

 able from it except by immaturity, the true L. solida does not 

 occur in this portion of California and the species is only intro- 

 duced here to give a clear understanding of the nomenclature 

 which is badly involved. In 1839, the year previous to the 

 publication of L. cubensis, Lea described Lymnaea solida from 

 the site of the present city of Portland, Oregon. The descrip- 

 tion is brief and the figure crude, while the copy in Binney's 

 Land and Fresh Water Shells, II, is even more unsatisfactory. 

 However, Lea unmistakably had before him one of the Galbas 

 or smaller Lymnaeas of the bulimoides-cubensis group. Since 

 L. bulimoides is the only representative found in this region
