Cardinalis cardiiialis mariae subsp. nov. Tres Maria Cardinal. 



Type No. 156907, U. S. Nat. Mus., Biological Survey Coll., ad. c?, Maria 

 Madre Island, Mexico, May 3, 1897. Collected by E. W. Nelson and 

 E. A. Goldman. 



Description. Males most like those of C. cardinalis igneus, but red of 

 under parts deeper and richer, lacking the pinkish suffusion notable in 

 igneus; color of back also richer, and feathers less edged with gray. 



The females of the two forms are more distinct than the males. C. 

 marise has a large whitish throat area, and the entire abdomen is whitish, 

 thus confining the main buffy area of lower parts to a broad pectoral 

 band. The bill is more swollen ; the wing is longer and tail shorter than 

 in igneus. Dimensions of type : wing, 101; tail, 103; culmen, 20; tarsus, 

 29.
