Subgenus Phyllonotus Swainson. 



The following sections may be considered synonyms: Bas- 

 sia^ Bayle, 1880 (type M. Stainforfhu Reeve); Poirieriay 

 Jouss., 1880 (type 31. Zelandicus Quoy and Gaim.); Pa- 

 ziella, Jouss., 1880 (type M. Pazi Crosse). No one has yet 

 been able to find characters of enough stability to form 

 sections of this extremely variable group.

The following sections have no distinctive value : Morchia 

 Jouss., 1880 (type M. clavus Kiener) ; Naquetia^ Jouss., 

 1880 (type M. triqueter Born.); Triremis Bayle, 1880 {M. 

 Gamhiensis Lam.); Poropteron Jouss., 1880 {M. uncina- 

 rius Lam.); Pteropurpura Jouss., 1880 (3f. macropteron 

 Desh.); Alipurpura^^y\Qt 1884(3/. acanthopterus Lam.). 

 It is difficult to conceive of what use these sections are to the 

 scientific world.
