88 PROCEEDINGS OF THE ACADEMY OF 



ends of the feathers deep black. Wing, 8. GO ; tail, 7.50; culmen, 

 .68; tarsus, 2.50 ; middle toe. 1.70. 



Young female (41,128, Cuba, Dr. Gundlach): Similar, but more 

 thickly striped beneath, the dark markings about equalling the 

 white in extent ; whole sides with large transverse spots of umber, 

 cuneate along shafts. Wing, 10.50 ; tail, 9.50. 



Remarks In regard to its relationship to its nearest allies N. 

 cooperi and N. pileatus Mr. Lawrence (1. c. p. 8) remarks: " A. 

 very marked feature in the adult of this species is the ash-color of the 

 breast and sides, which does not exist at all in cooperi; the under 

 surface is less marked with white than in that species ; the thighs 

 are of a nearly uniform rufous, which in cooperi are conspicuously 

 barred with white ; in the latter the under wing-coverts are white, 

 with longitudinal spots of rufous-brown, whereas in gundlachi 

 they are rufous barred with white. From A. pileatus, as figured 

 in PI. Col. pi. 205, it is also very different; the adult of that spe- 

 cies has the top of the head dark slate, the upper plumage of a 

 rather light slate-blue; wings, dark slate; tail, with four dark 

 bands, wdiitish between; the under plumage pale wdiitish-blue; 

 thighs, deep rufous; no appearance of bars on any part of the 

 plumage ; under tail-coverts, white ; bill, bluish, under mandible 

 yellow at the base ; legs, yellow." 



In the "History of North American Birds" (III.p. 223, foot-note), 

 this species is considered to be a geographical race of N. cooperi; 

 and Mr. Sharpe, in his great work the "Catalogue of the Accipi- 

 tres, or Diurnal Birds of Pre}', in the collection of the British 

 Museum" (p. 137, foot-note), remarks that it "will probably prove 

 on examination to be identical with the small, richly-colored form 

 of A. cooperi, called by Swainson A. inexicanus.' 1 ' 1 We have 

 shown before that the latter is not entitled to recognition as even 

 a race, though we had previously accorded it that rank, while Mr. 

 Sharpe (torn, cit., p. 137) more properly places it among the syno- 

 nyms of N. cooperi. In regard to the N. gundlachi, the erroneous 

 conclusions of both authors were the result of lack of specimens 

 for comparison, and too hasty examination of published descrip- 

 tions. The description of the adult, copied from the original 

 paper by Mr. Lawrence (Annals of the Lyceum of Natural History 

 of New York, VII., May, I860, p. 252), shows clearly the perfect 

 distinctness of the Cuban species from its North American ally, 

 as well as from all other species of the genus.
