162 OBSERVATIONS ON THE CHAROPID^, 



" Critical List of the Mollusca of New Zealand," 1873, p. 12, the 

 group (genus 1) Flammulina whose first species (type 1) is 

 B. omega, Pfr. 



From the above review of the geuera proposed, it will be seen 

 that the student of the Charopidce is better supplied with divisional 

 names than with definitions. 



The following authors have written upon the dentition of the 

 Charopidce^' : —

 Though it seems a bold assertion, I consider that no other 

 group of land shells is to-day so imperfectly understood, so mis- 

 represented in standard works, and so inefficiently figured and 

 described. Pfeiffer in his last volume of the " Heliceorum Viven- 

 tium " scatters broadcast among different sections the species I wish 

 to assemble under Charopidce. Of these forms Fischer (Manuel, 

 p. 470) only mentions Endodonta to associate it with Discus, Trocho- 

 morpha, &c, Hutton (op. cit. p. 200) recognises the genus Charopa, 

 yet on p. 191 he tears away from it the type coma, a proceeding not 



* The writer does not possess the opportunity of assuring himself by 

 personal inspection that all these species are correctly referred here.
