The specimen above described is essentially like numerous others 

 which I have examined in the collections of the United States jSTational 

 and American museums from Indianola, Eockport, Brownsville, and 

 other points in southeastern Texas. 



An adult male (Xo. f f|f , American Museum Coll.), taken at Eockport, 

 Texas, September 18, 1893, by Mr. H. P. Attwater, is in summer pelage. 

 The pelage is short and rigid. The upper parts are drab gray, mixed 

 with black; nape black, with a faint longitudinal band of grayish 

 posteriorly. The ears are very vshort-haired ; convex surface white pos- 

 teriorly, black apically, and finely mixed yellowish brown, gray, and 

 black anteriorly; fringe on anterior edge yellowish brown, on posterior 

 edge white; concave surface sparsely clothed with whitish and yellowish 

 hairs, with a broad blackish area along the posterior border. The gular 

 patch is wood brown mixed with grayish white; under side of tail smoky 

 gray, slightly mixed with long grayish white and reddish brown hairs; 

 residue of under parts white. 



Description of young.— K small female (No. 2302, Coll. International 

 Boundary Commission), about the size of a Neotoma, was taken from 

 a marsh hawk {Circus hudsoniiis), at Fort Clark, Tex., February 25, 

 1893, by the author. It is coated above with plumbeous, brownish- 

 pointed underfur, a median coat of banded hairs, and a sparse outside 

 coating of extremely long, white-tipped, coarse hairs. The nape is 

 sooty black. The general coloring is grayer than adults, and more 

 mixed with black on the haunches and rumi), and with darker under- 

 fur. A two-thirds grown male (No. -s-fff, Amer. Mus. Nat. Hist.), 

 taken at Eockport, Texas, by Mr. II. P. Attwater, November 8, 1893, is 

 in winter dress, except as to the middle of the back, and has a richer, 

 more brownish coloring than any other examined. The ears are quite 

 heavily coated on their concave surface, where they are decidedly 

 ochraceous toward the' apex and along the posterior border. The nape 

 and base of ears, posteriorly, are black.
