whitish; each feather being dark-colored, with a spot of chestnut toward its extremity, wl.icl; 

 in turn fades into whitish along the shaft toward tlie tip of each feather. On the latcro-nuchal 

 region and across the throat the chestnut lightens into a decided reddish-yellow, the white 

 being as a well-defined, narrow, longitudinal streak on each feather. The crown, post-ocular, 

 and mental region have but little whitish. Inferiurly the plumage is of a blended fusco-rufous, 

 lighter than on the dorsum, with a peculiar indefinite plumbeous shade. Tlie wings and tail 

 are blackish ; their shafts white, except toward the tips ; the remiges and rectrices white t(jr 

 some distance from the bases. This white on the tail is concealed by the long tail-coverts, 

 but appears on the outer primaries as a conspicuous spot. Bill and claws blackish-h(,irn ; 

 feet black. Bill from base to tip 2.10 ; to end of cere 1.20 ; gape 3.00 ; height at base 0.75 ; 

 width a little less; gonys 0.50; wing 16.00; tail G.OO ; tarsus 2.70; middle toe and claw 

 3.10. Young-of-tbe-year : The size much less, bill weaker and slenderer; cere illy developed ; 

 strife not apparent, and its ridges and angles all want sharpness of definition. Wings short and 

 rounded, the quills having very dift'erent proportional length from those of the adults; the 2d 

 being longest, the 3d next and but little shorter ; the 1st about equal to the 4th. The inner 

 or longest secondaries reach, when the wing is folded, to within an inch or so of the tip of the 

 longest primary. Central rectrices, if anything, a little shorter than the next. Cohjrs 

 generally as in the adult, but everywhere duller and more blended, having few or no white 

 spots ; the reddish spots dull, numerous, and large, especially along the edge of the forearm 

 and on the least and lesser coverts. On the under parts the colors are lighter, duller, and still 

 more blended than above. The prevailing tint is a light, duU rufous, most marked on the 

 abdomen ; but there and elsewhere more or less obscured with an ashy or plumbeous hue. 

 The primaries, secondaries, and tertials, together with the rectrices, are dull brownish-black ; 

 their shafts yellowish-white, darker terminally. At the bases of the primaries there exists the 

 ordinary large white space, but it is more restricted than in the adults, and so much hidden by 

 the bastard quills that it is hardly apparent on the outside of the wing, though very conspic- 

 uous on the inferior surface. Legs and feet parti-colored, — brownish-black, variegated with 

 yellowish. BiU along culmen 1.75; along gape 2.75; height at base 0.50; length of gonys 

 0.35; tarsus 2.60; middle toe and claw the same; wing 12.25; tail 5.75. N. Am., north- 

 erly, rare or casual. "California."

 nose.) PoHATORHlNE Jager. Adults, breeding plumage : Bill shorter than the head, or f 

 the tarsus, about 2i times its own height at the base ; width about the same as the height. 

 Tail somewhat less than half the wing. 1st primary but little surpassing the 2d. Occiput 

 subcrested. Feathers of the neck rigid and acuminate, their fibrillse disconnected. Tail- 

 feathers, includiug the central, broad quite to their tips, which are truncated, the rhacliis 

 projecting as a small mucro. The central pair project about 3 inches ; are broad to near the 

 tip, where they form an angle of 45° with the rhachis ; their fibrillaj exceedingly hjug (2f 

 inches), while those of the lateral feathers are only If. Tail slightly graduated. Tibife bare 

 for f of an inch, scutellate for i inch. Tarsi very rough ; anteriorly covered with a single 

 row of scuteUa, except toward the tibio-tarsal articulation, where these scutella gradually 

 degenerate into small, irregular polygonal plates, with which the whole of the rest of tlie 

 tarsus is reticulated. These plates largest on the sides of the tarsus externally ; on tlie heel- 

 joint, and posterior aspect of the tarsus generally, they become raised into small conical pyr- 

 amids, acutely pointed. The scutella of the anterior portion of the tarsus are continuous with 

 the superior surface of the toes, while tlie polygonal reticulation occupies both surfaces of the 

 webs, and the inferior surface of the toes. Hallux extremely short, its nail stout, conical at 

 the base, acute, little curved. Anteri<n- claws all very strong and sharp ; inner most so ; the 

 michlle expanded on its inferior edge, not serrated. Webs broad, full, unincised, their free 

 margins a little convex. The " cere " has a straight, smooth, convex culmen ; its inferior
