GUDE : CHANGES IN CLASSIFICATION OF HELICES. 159 



Helix devexa, Reuss, and H. coarctata, Klein, the former for type, 

 but later, ^ while raising Klihia to generic rank, he subordinated 

 Apula to the latter genus. 



Brusina proposed Vidovicia ^ as a new genus for the group of 

 Helix lacticina, Ziegl. ; Soos five years later ^ suggested the name of 

 Hazaya for Helix ccerulans, Muhlf . Now, lacticina being a synonym 

 ■of cosndans, Soos' designation becomes synonymous with Brusina's. 

 This group of Helices was included by Pilsbry in the section 

 Ghilostoma, Fitz., of the genus Helicigona, Risso. 



Further divisions of the groups of Helix included in Ghilostoma 

 by Pilsbry were made by Brusina ^ as follows : Drobasia for the 

 group of Helix banatica, Partsch (C. R. Boettger proposed Partschia * 

 for the same group) ; SaUjaria for the Helix stenoni'phala, Mke. 

 group, Cattania for H. trizona, Zglr., and its allies, Botteria for H. 

 setosa, Zglr., with five other species, and lastly Kosicia for Helix 

 intermedia, F., and two others. 



Helix vermicidata and its allies were placed by Pilsbry under his 

 section Otala, Schum. A considerable amount of exception has been 

 taken to this course by many Continental authors. Archelix, con- 

 sidered a synonym by Pilsbry, has been revived for this group by 

 Hesse,^ when he gave the result of his anatomical investigations 

 and published a list of species.^ At the same time he separated a 

 number of species to form two subgenera : Archelix s.s. and 

 Dwpotetia, the latter with two sections : Dupotetia s.s. and 

 Deserticola. Pallary also dealt with the genus '' when he illustrated 

 several species, and four years later established another section, 

 Tingitana ® for a group of species of Archelix, which in the immature 

 stage are strongly carinated and in the adult state have the earlier 

 whorls edged. He selected his Archelix minettei as type, and 

 described at the same time seven other species, together with several 

 varieties. 



Hesse proposed the subfamily Murellinse ^ for the following four 

 genera : Murella, Pfr. (considered a subsection of section Iberus 

 under Helix by Pilsbry), Opica, Kob.^°(many of the species placed 

 in subsection Macidaria by Pilsbry), Marmorana (Hartm.), Kob.,^^ 

 and Tyrrheniberus, Kob. & Hesse.^^ Most of the species arranged
