CATALOGUE OF SPECIES. 
The material afforded by these collections has warranted the estab- 
lishnnent of four new genera, viz, Coaxana, Deanea, Neogoezia, and 
Neonelsonia, of which the first and last are here first published. It 
has also necessitated a revision and enlargement of Museniopsis. The 
list includes some species additional to those named above.
