P. L. SCLATER ON NEW GENERA [JuQC 21, 



1. Bacno, Linn 20 species. 



2. Malacoptila, G. R. Gray 7 



3. Micromonacha, gen. nov 1 



4. Nonnula, Scl 4 



5. Hapaloptila, geu. nov 1 



6. Monacha, Vieiil 7 



7. Chelidojptera, Gould 2^ 



Total 42 species. 



It will thus be seen that in the present work the genera have been 

 increased from 4 to 7, and the species from 33 to 42 \ 



1 append short distinctive characters of the two new genera, and 

 of a new species of the genus Nonnula, from an example in the 

 British Museum, which Dr. Giinther kindly allows me to make known.

 divided the family into 11 genera and recognized 50 species, namely : —
