[441.1.] Xantus Beoard. PUitjjpsriris atbircntris. 



Range. — Mexico; north casually to the southern liorder of Arizona. 



This peculiar species is grayish above and lighter gray 

 below, has dark slaty crown, and a patch of rose color on 

 the lower throat. This is the only representative of this 

 tropical family that has been found as yet over the Mexican 

 border, but its near ally, the Rose-throated Becard has been 

 found within a very few miles and will doubtless be added to 

 our fauna as an accidental visitor ere long. Their nests are 

 large masses of grasses, weeds, strips of bark, etc., partially 

 .suspended from the forks of branches. Their eggs number four or five and are 

 a pale buffy gray color, dotted and scratched with a pale reddish brown and dark 

 gray. Size .95 x .70. The one figured is from a set in the collection of Mr. Cran- 

 dall, taken June 1, 1897 at Presidio Sinaloa, Mexico.
