GUDE : CHANGES IN CLASSIFICATION OF HELICES. 153 



follow suit. In the same article Von Ihering established the family 

 Pleurodontidee for the reception of Solaropsis, Beck. Chlorites, 

 Beck, and Pleurodonta, Fischer, the first included by Pilsbry in 

 Protogona, the last two in Epiphallogona (Camseninae). 



Moellendorffia, Anc, included under Helicodonta as a subgenus 

 by Pilsbry, was subsequently raised to generic rank by him,^ with 

 two subgenera added : Moellendorffiella, Pils., and Trihelix, Anc. 

 These with Traumatojihora, Anc, and Stegodera, Mart. — formerly 

 regarded by him as subgenera of Plectopylis — were now considered 

 to have more affinity with Chloritis. 



Corasia hourdilloni, Theob. — placed in Nanina by Nevill, in 

 Cochlostyla by Pilsbry — has been made the type of a new genus, 

 Apatetes,^ by me, coming before Ganesella. 



The genus Chloritis has received many additions during this 

 period, and it became necessary still further to subdivide it. In 

 1906 I proposed a nev/ section, Eustomopsis,^ and included the 

 genus Alhersia, H. Ad., as another section at the end of the genus. 

 My list of species at the time reached the total of 204, to which 

 eleven more were added in 1907.* Ehrmann in 1911 ^ proposed the 

 genus Parachloritis, taking as type Eulota telitecta, Mlldff., with a 

 new species added, P. sericata. Godwin-Austen created another 

 genus, Burmochloritis, in 1920," for the reception of a new species, 

 B. kentungensis, which he had dissected. This will probably class 

 as a subgenus. 



The genus Strophocheilus, Spix., previously included in Bulimus, 

 was shown to belong to Acavidae by Pilsbry.'^ It comprises the 

 subgenera Bonis, Alb., and Dryptus, Alb., totalling some forty-six 

 species. The genus Gonyostomus [melior Goniostomus], Beck, with 

 five species, follows likewise. 



Plectopylis and Gorilla, located with some doubt between 

 Acavin^ and Sagdinse by Pilsbry, I have placed in a subfamily, 

 Corillinse,® next to Acavinse. 



Enterovlax, proposed by me as a section of Plectopylis in 1899 ° for 

 three small Philippine species, has been merged into the genus 

 Strohilops by Pilsbry,^" who substituted the latter name " for Strobila, 

 Morse, 1864 (preoccupied)^ when he stated it was of doubtful 

 position, but subsequently ^^ referred it to Pupidse (= Pupil! idae),
