420 NORTH AMKRICAN HI UPS. 



vt'iy loud of tlie little cliau^caljlL' ^rot-ii lizard, wliicli it pursues with <;reat 

 skill aud acti\ity, lait uot always with success. 



It is said also to breed twice iu a season. Dr. I'lachnian deserilies their 

 ejijfs as white, aud Afr. Audubon sjjcaks of them as greenish-white. Neither 

 make any reference to their spots. 



All the nests that I have ever seen of this species, in the simplicity of 

 their structure and in their lack of elaboration, are in remarkable contrast 

 with the nests of both the huiralix and the cirHhi/oiviilcs. They are flat, 

 shallow structures, with a hei^dit of aljout two inches and a diameter of five. 

 They are uiade e.vternally of long soft strips of tiie inner bark of the bass- 

 wood, strengthened on tiie sides with a few dry twigs, stems, aud roots. 

 Witiiin, it is lined with fine grasses and stems of herliace(ais plants. 



The eggs, often si.x. in number, are in length from 1.02 to 1.U8 inches, and 

 from .72 to .78 of an inch in breadth ; their ground-color is a yellowish or 

 cLiyey-white, blotched aud marbled with dashes, more or less confluent, of 

 obscure purjde, light brown, and a purj dish-gray. The spots are usually 

 larger aud more scattered than in the eggs of 6'. horndin, and the ground- 

 color is a yellowish and uot a bluish white, as in the eggs of C. cxciihitoroidcs.

Ham. Caliloniia? 



The description already given is taken from a specimen iu the collection of 

 the Philadelpiiia Academy, labelled as having been c(dlected in California by 

 Dr. (Jambel, and is very decidedly different from any of the recognized North 

 American species. Of nearly the size of C. cjviihitoi'oidcs and litdovicianus, 

 it has a bill even more powerful than that of C. bunudU. In its iiuwaved 

 under parts and uniform color of the entire ujjjter surface, except scapulars, 

 it differs from honvlia and e.irid/ifuruidi's, and resemldes li't/orivictniia. In the 

 extension of white over the inner webs of the secondaries, it clo.sely resem- 

 bles 0. (■jxi'lito): The great restriction of white at the base of tlie tail — 

 the four central featliers being entirely black, aud the bases of the others 

 grayish-ashy — is (juite peculiar to the species. 



Tiie specimen iu tlie Philadelphia Ai ademy we originally referred to the 

 L. ilcjimiH of .Swaiusou, alleged to have come from the fur couutri(!S, as al- 

 though some appreciable dill'ereuces presented themselves, especially in the
