which are more sharply defined than In continental ones, precisely as 

 the boundaries of the region they inhabit are more distinctly marked. 



Falco. 



Tinnunculus. 

 Falco dominicensis Gmel. Several specimens of a small hawk, 

 presenting no very appreciable character by which it can be distin- 

 guished from this species. One of the principal characters of the 

 Linnaean genus Falco is the variety in plumage presented by the dif- 

 ferent individuals of the same species, and in none of those with which I 

 am acquainted is this carried to a greater extreme than in the present. 

 During a short visit to Cuba in the spring of 1863, I examined a very 

 large number of individuals, and was unable even to form an opinion 

 as to what should be considered its normal type of coloration, so unlike 

 each other were the numerous specimens procured by me. 



Tyr annus. 

 Tyr annus. 

 Tyrannus dominicensis Gmel. Several specimens. 



Pitangus. 

 Tyrannus Taylori Sclater. Several specimens. 

 Myiarchus. 



Tyrannus antillarum. Several specimens. This species? does 

 not resemble particularly any other known to me. I presume it is 

 the same referred to in Taylor's list, and not unUkely the same as the 

 Tobago Bii'd in Jardine's catalogue of the birds of that Island. Its 

 most striking character is the almost total absence of rufous in the 

 tail. 



No. 36,459. Length of dried skin, 170 mm.*\ wing from flexure 

 86-| ; tail 68 ; tarsus 21 ; middle toe and claw 19; claw alone 7; 

 bill along ridge 21 ; 4th primary longest, 1st, 7th, 2d, slightly shorter 

 than 4 th. 



Head above fuliginous-bi-own ; hind-neck, back and scapulars dull, 

 dirty, olivaceous-brown, becoming paler on the rump and somewhat 

 rufous on the upper tail coverts. Wing dark brown, the middle and 

 greater coverts broadly margined with dull whitish faintly tinged with 

 rufous-olive, and with all the remiges, except perhaps the first, mar- 

 gined externally with paler, most distinctly so on the inner secondaries 

 where the color is nearly similar to that of the border of the greater 

 coverts ; this color is gradually shaded into quite distinct rufous on the
