 (Australian branch.} 



Section HADRA, restricted. 



Subsection HADRA. Type H. bipartita Fer., p. 126. 

 Subsection BADISTES Gld. Type H. gulosa Old., p. 129. 

 Subsection THERSITES Pfr. Type H. richmondiana Pfr., p. 90.

 Subsection XANTHOMELON Martens. Type H. pomum Pfr., p.

Section RHAGADA Albers, 1860. See p. 184. 



Subsection GLYPTORHAGADA Pilsbry. Type H. silveri Ang. 

 p. 191. 



Subgenus XX. ANOGLYPTA Martens, 1860. See p. 92. 



This group has probably nothing to do with Hadra (+ Thersites'), 

 and may stand for the present as a distinct subgenus. It is possible 

 that an examination of the dentition will prove Anoglypta to belong 

 to the Zonitidce. The animal is unknown. 



* * * . 



It will be understood that I give but little value to the Australian 

 subsections of Hadra. They simply represent the more salient or 

 extreme aspects of variation, and are connected by forms more or 

 less intermediate. 



EUHADRA. 



The Japanese species of the H. peliomphala group are excessively 

 variable, and the number of specific types must be considerably re- 

 duced. Kobelt has pretty thoroughly worked them up in his work 

 Fauna molluscorwn extramarinorum Japonic?, 1879. I suggest the 

 following as a rearrangement of the varieties of H. luhuana Sowb. 

 This name must take precedence over H. peliomphala Pfr., as it is 

 several years earlier.
