Balanosphyra o Ridgwat, Proc. Biol. Soc. Wash., xxiv, Feb. 24, 1911, 34. (Type, 

 Pints formidvorus Swainson.) 



Medium-sized Picid® (wing about 130-151 mm.) similar to Mela- 

 nerpes, but with antrorse prefrontal feathers developed into conspicu- 

 ous dense tufts, feathers of breast broad and imbricated, eighth, 

 seventh and eighth, or sixth, seventh, and eighth primaries longest, 

 niuth primary nearly as long as fifth, and tenth (outermost) relatively 

 much smaller (about one-fourth as long as ninth), narrower, and more 

 acuminate. 



Bill about as long as head or shorter, stout, cuneate in vertical pro- 

 file, slightly broader than deep at nostrils; culmen slightly but dis- 

 tinctly convex, distinctly but not sharply ridged; gonys usually twice 

 as long as mandibular rami, nearly straight, ascending terminally, very 

 slightly (if at all) prominent basaUy; supranasal ridge distinct for 

 basal half or more of maxilla. Nostril longitudinally oval, rather 

 large, situated about midway between culmen and tomium, covered 

 by a very conspicuous prefrontal tuft, the feathers comprising which 

 are antrorse anteriorly, dense and semierect posteriorly; malar apex 

 with distinct bristle-like antrorse feathers, and feathers of chin with 

 distinct though relatively short semiantrorse bristly tips. Margin of 

 eyelid densely clothed with short and minute feathers, with a naked 

 crescentic space immediately above and below. Wing long, pointed, 

 the longest primaries exceeding secondaries by one-third the length of 

 wing; eighth, seventh and eighth, or sixth, seventh, and eighth pri- 



1 ^iXavo(, an acorn; a^Opa, a hammer.
