40 MR. GAMBEL ON THE BIRDS OF CALIFORNIA. 



52 S. *BAiRDii, Gamb. Baird's Lizard-eater. 



Head, sides of neck, back and scapulars, greyish brown; rump, tail and exterior margins of wing-feathers 

 and coverts, bright ferruginous ; wings, with the exception of their broad outer and inner margins, 

 shafts of the tail-feathers and streak on each side down their centres, hair brown; throat greyish ; 

 upper part of breast dirty yellowish ; all the rest beneath dull sulphur yellow, tinged on the sides and 

 beneath the wings with ferruginous, brightest on the belly and thighs, and becoming somewhat duller 

 on the lower tail coverts ; front and broad line to eye black ; auriculars dusky ; feathers of the toj) of 

 the head, except at their tips, bright orange yellow ; bill and feet dusky, base of lower mandible pale. 

 Tail even. 



Leno-th 9 inches ; wing from flexure 4| inches ; tail 4<i inches ; tarsus 1 inch ; bill along ridge I of an inch ; 

 from angle of the mouth li inches. 



This interesting species forms a connecting link between the genera Sauropliagus 

 and Myiohius, but from its colours and general appearance seems to belong more 

 properly to the former. It is readily distinguished from the S. sulphuratus by the 

 entirely different markings of the head ; its bright ferruginous rump ; the dulness 

 of its colour beneath; and by its very different proportions. The bill is much 

 smaller ; the tail longer ; and the tarsi, though of the same length, very much more 

 slender and delicate. 



For the opportunity of describing this fine species, I am indebted to my friend 

 Prof S. F. Baird, of Carlisle, Pennsylvania; who received it from California, and [in 

 honour of whom it is named. 



TYRANNUS, Vieill. 



53. T. cooPERii, Nutt. Olive-sided Flycatcher. 



T. horealis, Swains. 

 I found this species scatteringly in the Rocky Mountains : it is quite abundant in 

 in the pine woods of upper California, for which it appears to have a great partiality. 

 In the latter part of July I killed the young, not yet fully fledged, in the pines near 

 Monterey, where they must have bred. 



54. T. VERTiCALis, Say. Arkansas Flycatcher. 



This tyrant is an abundant resident in California. Around the Pueblo de los 

 Angeles it takes possession of the hedges of the vineyards, orchards and gardens ; 

 noisy, pugnacious, and ever on the alert, it suffers no intrusion upon its dominions ; 

 Hawk, Raven, or Crow, not even its own species, are allowed to pass unmolested. 

 For this reason it has acquired the name of Correcuerto (Crow-chaser) by the inhabi- 

 tants, who also gladly allow them full possession. 



PTILIOGONYS, Swains. 



55. P. TOWNSENDii, And. 



This rare and singular bird, of which but a single specimen has been obtained in 

 Oregon, I first met with, in October, on the banks of a small rocky creek, in the
