6 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 60 



a thin patch of bluish green on chin ; the usual black breast spot ; 

 lores and area under and behind eyes black ; back nearly grass green ; 

 upper tail coverts bluish green ; top of wings mainly bluish green but 

 outer borders of primaries distinctly bluish ; upper side of tail bright 

 bluish green, varying to cyanine blue on ends of tail in certain lights, 

 the blue on tail much stronger and clearer than in minor; a poorly 

 defined margin of bluish grass green about posterior border of 

 rufous on breast changing to cserulean blue with a greenish tinge on 

 abdomen and a greener shade of same on under tail coverts. Bill 

 narrower and longer than in minor and black to tip, thus lacking 

 the pale horn colored tip of latter. 



Measurements of type. — Wing, 116; tail, 177; culmen, 45; tarsus, 



17- 



Remarks.' — This subspecies differs strongly from E. p. minor, 

 the most striking differences being in its long slender bill, paler 

 colors and the distinctly bluish cast of the top of the wings and tail 

 and the blue abdomen. The present bird agrees with minor in size 

 and is thus much smaller than typical platyrhynchus. Hartert gives 

 the measurements of a typical specimen of the latter from Paramba, 

 Ecuador, as follows: Wing, 130; tail, 223; culmen, 49; tarsus, 20. 

 The bill of subolcs is actually as well as proportionately narrower 

 than in either of the forms named above. This form is based on a 

 single specimen. 



GOETHALSIA, 1 gen. nov. 

 Apparently nearest Goldmania, the three or four middle under 

 tail coverts being shorter than usual and specialized as in that genus, 

 silky white in color and forming a tuft of overlapping or " nested " 

 and strongly decurved stiff plumes about twice as long as in Gold- 

 mania and more plume-like nearly to base of feathers ; other under 

 tail coverts normal and differently colored from middle ones but 

 proportionately smaller than usual ; this strong character present in 

 both sexes and in the young as in Goldmania; primaries medium 

 width, broader than in Goldmania, normal in all conditions ( ?) and 

 outer primary distinctly longer than next one ; tail emarginate, nearly 

 three-fifths the length of wing ; bill slightly broadened and ridged 

 at base, terete elsewhere and same length as head ; nostrils operculate, 

 feathering of forehead extending out about two-thirds of length of 



Earned in honor of Colonel George W. Goethals, head of the Panama 

 Canal Commission, to whom the scientific workers of the Biological Survey 

 of the Canal Zone are deeply indebted for prompt and courteous assistance in 

 prosecuting their work.
