 slightly arched posteriorly, more or less flattened, especially between 

 the nostrils; gonys straight or faintly convex, slightly shorter than 

 distance from nostril to tip of maxilla; commissure nearly straight to 

 near base, where deflexed to the rictus, the maxillary toiuium some- 

 times more or less convex in middle portion. Nostril small, roundish, 

 or oblong, with membrane above and behind, its posterior end touch- 

 ing feathering of frontal antiaj. Wing moderate or rather long (less 

 than five to nearly seven times as long as culmen, three and a half to 

 more than four times as long as tarsus), pointed; wing-tip variable in 

 length, from less than length of culmen (in 3L hadius) to more than 

 twice as long (in M. n(fo-axillarls)\ tertials not produced; ' ninth (outer- 

 most) primary longer than fifth, usually longer than sixth, sometimes 



^ The drawing of generic details is incorrect in showing a projection of the longest
