J l6 Brewstek. Descriptions of Nezv Birds. [April 



Habitat. — Dakota, — and probably other regions along the 

 eastern border of the Great Plains. 



Two other specimens in my collection, taken in the same locality 

 at nearly the same date, are similar in every respect save that 

 one has a trifle more chestnut on the back although much less of 

 this than have any of the large number of Eastern birds before 

 me. Several examples from Illinois are a shade paler than those 

 from the Atlantic States, but I refer them all, without hesitation, 

 to hcnslozvii. Massachusetts specimens are neaily as white be- 

 neath as occidentalism but their upper parts are marked and col 

 ored like those of the birds that breed near Washington, D. C, 

 which probably most nearly represent true henslowii. 



Pipilo maculatus magnirostris, new subspecies. Moun- 

 tain TOWHEE. 



SuBSPEC. CHAR. — Similar to P. m. megalonyx, hut with the bill much 

 larger, the rufous of the under parts paler, the upper parts browner and 

 tinged with olive. Female very decidedly lighter than the male. 



hfale ad. (No. 16,070, collection of William Brewster, Sierra de la 

 Laguna, Lower California, May 21, 1887; M. Abbott Frazar). Upper parts 

 "enerallv, with the head and neck all around to the upper part of the 

 breast, dull black, the back and rump mixed with brownish olive, the 

 wing quills dark olive brown; white markings of the back, scapulars, 

 wino--coverts, wings, and tail, about as in typical megalottyx\ middle of 

 breast and belly white; sides rusty ochraceous; flanks and under tail- 

 coverts brownish buff. Wing, 3.37; tail, 3.85; tarsus, 1.08; length of bill 

 from nostril, .42; depth of bill at nostril, .40 inch. 



Female ad. (No. 16,081, collection of William Brewster, Sierra de la 

 La"-una, Lower California, May 21, 1S87; M. Abbott Frazar). — Similar to 

 the male just described but with the black everywhere replaced b_y gray- 

 ish brown, tinged with olive on the back, darkest on the upper part of 

 the breast; feathers of the crown streaked centrally with orange rufous. 

 Win"-, 3.28; tail, 3.71; tarsus, 1.07; length of bill from nostril, .41; depth 

 of bill at nostril, .39 inch. 



Habitat. — Cape St. Lucas Region of Lower California. 



The proper assignment of the Towhees of the P. maculatus 

 o-roup taken by Mr. Frazar in Lower California is a matter of 

 some difficulty. With respect to the white spotting of the scap- 

 ulars, wings, and tail, they agree very well with megalonyx. But 

 the rufous of the flanks, sides, etc., is quite as pale or ochraceous
