32 ZOOLOGY. 



64. PICICORVUS COLUMBIANUS, Bon. (p. 573.) Clark s Crow. 

 8474, 8475. 75 miles west of Albuquerque, November 15, 1853. K.. & M. 



In the thick pine woods skirting the eastern slope of the Rocky mountains we found this bird 

 quite abundant. We seldom saw more than two or three together ; and when seen they were 

 generally busily engaged in searching for food, flying alternately from the ground to the trees, 

 and keeping up continually their loud song. After leaving the mountains we did not see 

 it again. 



65. GYMNOKITTA CYANOCEPHALA, Pr. Max. (p. 574 ) Maximilian s Jay. 

 8468. 95 miles west of Albuquerque, November 16, 1853. K. & M. 



Between the Puebla of Laguna and the Sierra Madre we frequently saw large flocks of this 

 bird during the latter part of the month of November. They frequented chiefly the water 

 courses, and when scared would circle around rising higher above our heads, uttering their 

 singular cry, then suddenly descending would alight in the top of some tree on the adjoining 

 cliffs. Its voice somewhat resembles that of the common cat-bird (Mimus carolinensis.) After 

 leaviog the Rocky mountain range we saw it no more. 



66. PICA HUDSONICA, Bo nap. (p. 576.) Magpie. 



8480. Fourth Camp, Little Colorado, New Mexico, December 8, 1853. Kennerly and 

 Mollhausen. 



We found this beautiful magpie in great numbers soon after leaving the Rio Grande, and from 

 time to time afterwards as we marched towards the coast of California. It seems to live indiffer 

 ently in the deep canons, among the hills, or in the valleys, but is never found except in the 

 vicinity of water. 



67. CYANURA MACROLOPHUS, Baird, (p. 582.) Crested Jay. 



8351. One hundred miles west of Albuquerque, New Mexico, November 17, 1853. (20.) 

 Camp 105, January 23, 1854. (53.) Kennerly and Mollhausen. 



First described from these specimens. 



Among the lofty pines of the Sierra Madre we first saw this bird. Leaving this range we did 

 not find it again until we crossed the Aztec mountains ; here it was less abundant than in the 

 former place, and for the most part was found among the cedars on the high grounds, though 

 sometimes seen among the clumps of large pines that were scattered along the valley. After 

 leaving this vicinity we did not observe it again. 



68. CYANOCITTA CALIFORNICA, Strickland, (p. 584.) California Jay. 

 8462. Camp 149, California, March 16, 1854. (186.) Kennerly and Mollhausen. 



We found what we supposed was this bird from the Rocky mountains to the coast of California, 

 wherever we found the piiion trees. It is probable that they feed upon the nuts of this tree. They 

 seldom remain long in one position, but are almost continually hopping from limb to limb, or 

 flying from tree to tree, and keeping up all the time their well-known cry. It is probable, however, 

 that all those seen east of the Coast mountains of California were in reality C. woodhousii.
