Genus EUCONULUS Reinhardt. 



The term Euconulus was proposed by Reinhardt in 1883 for the 

 typical group of Conulus, in which he included Kaliella. Conulus 

 being preoccupied, Pilsbry in 1900 27 substituted Euconulus for the 

 generic group, with fulvus as type. Dall, 1905, 28 has given the generic 

 synonymy and references in full. Mr. J. W. Taylor in his monograph 

 of British land shells (1908) has discussed the varieties of E. fulvus. 

 His treatment of E. cher sinus as a variety of fulvus was evidently due 

 to the lack of specimens, for the two forms are much less alike than 

 the several small British species of Hyalinia which he distinguishes, 

 and in fact are unusually distinct as species go among the small Zoni- 

 tidae. One of the European forms is apparently close to chersinus; 

 but an intelligible exposition and revision of the Euconulus of Europe 

 remains a desideratum. There is no trustworthy record of Euconulus 

 fulvus from Japan, though E. fulvus alasketisis may naturally be 

 expected to occur in the Kuril Islands, Yesso and Saghalin.
