billed Woodpecker of the United States, Picas principalis, as the latter 

 does the Pic. Martins of Europe. Mr. Gould described it as the 

 Picus imprriams, Mas. Pic. ater, virescenti splendens ; cristd elon- 

 gatd occipitali coccined ; maculd triangulari inter scapulari, remi- 

 gibus secundariis, primariarumque (prater triurn quatuorve exle- 

 riorum) rhachibus internis albis ; rostro eburneo. 

 Foem. Paullo minor ; cristd occipitali cum corpore concolore. 

 Longitudo maris, 2 ped. j alee (clausse), 1 ped. ; caudce, 10 unc. j 

 tarsi, vix 2 uric, j digiti externi postici, eadem ac tarsi. Ungues 

 validissimi, arcuati j Rostrum exacte cuneiforme, a rictu ad 

 apicem 4 uric, long., ad basin 1 unc. latum. 

 This species is readily distinguishable from the Pic. principalis by 

 its much larger size j by the length of its occipital crest, the pendent 

 silky feathers of which measure nearly 4 inches ; by the absence of 

 the white stripe which ornaments the neck of that bird - } and by the 

 bristles which cover its nostrils being black, whereas those of the Pic. 

 principalis are white.
