38 NORTH AMERICAN BIRDS.

2. P. aestivalis. Above uniformly marked with broad streaks or lon- 

 gitudinal blotches of deep rufous ; black streaks confined to interscapu- 

 lars and crown. Tail-feathers without darker shaft-stripe, and without

 .25 ; tar.sus, .80 ; middle toe, .63. Hah. Southern border of the

3. P. cassini. Above marked everywhere with broad short streaks of 

 pale (not reddish) brown streaks, all black medially. Tail-feathers with 



1 Zmwtriekia hoiicardi, Sclatei:, 1\ Z. S. 1867, 1, pi. i, La Putbla, Mex. (scarcely (Iffniahli' 

 as distinct from I'lificcp.s). 



^ Peuccca botterii, Sclatkr, Cat. Am. B. 1S62, 116 (Zoiiotriclna b. P. Z. S. 1857, 2U), Ori- 

 zaba. Coturniculus mexicana, L.iwr. Ann. N. Y. Lye. VIII, 1S67, 474 (Colima). 



This form can scarcely be defined separately from CKstivalis. The type of C. mexicanus, 

 Lawr., is undistingiiishable from Orizaba specimens. A specimen in the worn summer plumage 

 (44,7529, Jlirador, July) differs in having the streaks above almost wholly black, with .scarcely 

 any rufous edge ; the crown is almost uniformly blackish. The feathers are very much worn, 

 however, and the specimen is without doubt ref'errible to bolteri. 



The Peucaxi notosticta of ScLATER (P. Z. S. 1868, 322) we have not seen ; it apjiears to differ 

 in some important respects from the fonus diagnosed above, and may, possibly, be a gooil species. 

 Its place in our system .appears to be with section "A," but it differs from »-«/ffyw and boucardi 

 in the median stripe on the crown, and the black streaks in the rufous of the lateral portion, 

 the blacker streaks of the dorsal region, and some other less import.mt points of coloration. The 

 size appears to be larger than in any of the forms given in our synopsis (wing, 2.70 ; tail, 3.00). 

 Hab. States of Puebla and Mexico, Mex.
