^ ^ By ROBERT RIOGW^AIT. 



t 

 'P Granatellus sallaei boucardi, subsp. nov. 



Granatellus sallcei, Salv. & GoDM., Biol. Centr.-Am. Aves, I., 1881, 161 (part; 

 spec's ex Yucatan).— Boucard, P. Z. S., 1883, 441 (Yucatan). 



Sp. char. — Similar to G. sailed, Sol., but with chin and throat light 

 plumbeous-gray instead of deep plumbeous, the upper parts decidedly 

 paler plumbeous, the red of the breast paler, and the wing shorter. 



Adult $ (type, No. 81760, TJ. S. I^at. Mus., Yucatan, 1879, A. Boucard) : 

 Above bluish plumbeous, the sides of the crown bordered by a broad 

 but rather indistinct black line, beneath which, and extending from the 

 upper posterior portion of the eye over the auriculars to tbe occiput, is 

 a broad stripe of white ; auriculars and cheeks lighter plumbeous than 

 the upper parts, and the lores, malar region, chin, and throat still 

 paler, or light ash-gray. Entire breast, middle of abdomen (longitud- 

 inally), anal region, and crissum fiue pale rose-red; lining of wing, 

 sides, and flanks, pure white. Tail black, the feathers edged, especially 

 towards the base, with bluish plumbeous; tips of two outer rectrices 

 narrowly white, and shaft of outer rectrix entirely white. Wing, 2.30; 

 tail, 2.40; culmen, .55; depth of bill at base, .20; tarsus, .75; middle 

 toe, .45. 



An adult $ of G. sallcei, Sol., from Protrero, near Cordoba, Mexico 

 (No. 41599, U. S. Nat. Mus.),measure8 as follows: Wing, 2.50; tail, 2.40; 

 culmen, .55; depth of bill at base, .20; tarsus, .75; middle toe, .45. 

 There is, therefore, no difference in dimensions except in the length of 

 the wing, but the two forms may be easily distinguished by the marked 

 difference in their coloration.

 part of crown rich sky-blue, gradually passing anteriorly into silvery 

 white; rest of head and neck, together with upper part of jugulum and 

 back deep black, gradually changing, on breast, back, and scapulars to 

 Berlin blue, this in turn changing, on remaining portions, above and 

 below, to deep Paris blue, the tail with a greenish cast in certain lights.
