212 Ridgway — New Genera of Tyrannidse and Tiirdidas, dr. 



Haplocichia* gen. nov. 



Nearest Mimociclda Sclater but tail relatively shorter (not longer than 

 distance from l)end of wing to end of secondaries) and less strongly rounded 

 (nearly even), eyelids normally feathered, and with no white on rectrices, 

 but winw with an elongated white jmtch involving outer web of two inner- 

 most greater coverts. 



l^ype. — Turdas cmrantlus Gmelin = Haplocichla auranthi. 



Chlorospingus zeledoni sp. nov. 



Type from Volcan de Irazu, Costa Rica, 10,500 ft. alt. No. 19r),49S, U. S. 

 National Museum, c? ad. May 20, 1905 ; R. Ridgway. 



Similar in pattern of coloration to Chlorospingus pileatus Salvin, but color 

 of chest, sides, and flanks pale yellowish olive, not distinctly contrasted 

 with the pale gray of throat and abdomen (instead of bright olive-yellow, 

 strongly and abruptly contrasted with gray of abdomen, etc.), olive of back, 

 etc., rather duller, and black of head less intense (slightly more slaty). 

 Young very different in color from that of C. pileatus, the back, etc., 

 grayish olive (instead of olive-green), the ground color of underparts pale 

 brownish gray instead of olive-yellow. 



Higher parts of volcanos of Irazii and Turrialba, Costa Rica, at upper 

 limit of forest and lower portion of ash-cones (altitude about 9,000-10,500 

 feet. 



This species is found in the same localities with C. pileatus, both on Irazii 

 and Turrialba; consequently, there being no question as to its being 

 different it must, notwithstanding the character of the differences, be given 

 specific rank. There is a considerable series of this form in the Costa Rican 

 National Museum, that in the collection of the U. S. National Museum con- 

 sisting of eleven adults and one young bird in first plumage. 



I refer to this form with much doubt a single specimen (an adult male) 

 obtained by me on the Volcano of Turrialba May 2, 1905. This differs 

 from all others in greater length of the tail (which measures 07.5 nnn., the 

 maximum of four males of true C. zeledoni being 65, the minimum 61 mm. 

 and of six females 64 and 55 respectively), and in the almost total absence 

 of any olive tinge on the underparts, which are of a nearly uniform })ale gray, 

 only the sides and flanks being distinctly tinged with pale olive-green. The 

 back, etc., are also very much duller and grayer olive-green. 



Named for Don Jose C. Zeledon, of San Jose, Costa Rica, my companion 

 during many pleasant and successful collecting trips in Costa Rica. 



Phoenicothraupis alfaroana sji. nov. 



Th/pe from Miravalles, Guanacaste, Costa Rica. No. 199,961, U. S. 

 National Museum. J* ad. August 23, 1895; C. F. Underwood. 



'Most like Phanicothraupis rubra (Vieillot), of Venezuela and Trinidad, 

 but duller in color, the adult male with rump, upper tail-coverts, and wings 

 much less reddish (browner), and red of underparts paler and passing into 

 reddish gray posteriorly, the adult female with upperparts much grayer 



* 'Air\6vi, simple, plain ; kLx'^V, " thrush-like bird.
