368 NEW BIRDS FROM TEE GALAPAGOS ISLANDS— RIDG WAY. vol. xvii. 



brown (very nearly same color as in P. carolensis). Length (skin), 

 4.95; wing, 2.55 (!)*; tail, 2.10 (?); exposed ciilmen, 0.48; width of 

 bill at base, 0.23 ; tarsus, 0.75. 



Another adult male (No. 116135, U.S.lSr.M,, same date, etc.) is similar, 

 but has the pileum deeper red (intense vermilion) and the fore neck and 

 chest slightly tinged with vermilion. Exposed culmen, 0.45; width of 

 bill at base, 0.25; tarsus, 0.73. (Wing and tail too imperfect for meas- 

 urement.) 



An adult male from Bindloe Island, in Dr. Baur's collection, is simi- 

 lar in color of back, etc., to these Abingdon examples, but the under 

 j)arts are very different, the anterior half being pure scarlet and the 

 posterior half, very abruptly pale saturn-red. The bill is also extremely 

 narrow. Whether the differences are of an individual character or char- 

 acteristic of the locality can not be determined from only one specimen. 



Measurement— Length (skin), 4.40; wing, 2.48; tail, 2.12; exposed 

 culmen, 0.40; width of bill at base, 0.20; tarsus, 0.67. 



PYROCEPHALUS DUBIUS, Gould. 



Pyrocejihnlus dubhis, Gould, Zool. Voy. Beagle, Birds, 1841, 46. 

 Pyrocephalus nanus, Auctokum, part, not of Gould. 



Pyrocephalus minimus, Ridgway, Proc. U. S. Nat. Mus.. xiL No. 767, p. 113, in text, 

 Feb. 5, 1890 (Chatham Island, Galapagos). 



This very distinct form was sepaiated by me, provisionally, from P. 

 nanus, as P. minimus, in thepaper above cited, without being described 

 in detail. The fourteen specimens subsequently received bring out 

 very strongly its distinctive characters, and show it to be very different 

 indeed fi-om P. nanus and its nearer allies, from which, in any plum- 

 age, specimens may be distinguished at a glance. The different plum- 

 ages represented in the series before me may be described as follows: 



Specific characters. — Decidedly smaller than P. nanus Gould and 

 other Galapagoan forms; adult male with lower parts conspicuously 

 paler and duller red than pileum; back, etc., lighter and browner 

 than in other forms; adult female with conspicuous superciliary stripe 

 and under parts deep ochraceous-buff", the throat paler, but scarcely 

 approaching white. 



Habitat. — Chatham Island, Galapagos. 



Adult male (No. 72, colh Dr.G.Baur, Chatham Island, June 18, 1891).— 

 Entire i^ileum glossy dark vermilion, exactly as in other forms; lower 

 parts pale scarlet, deepest on breast, much paler on throat, and still 

 more so on chin, which inclines to reddish white. Lores, ear coverts, 

 and upper parts in general deep brown (intermediate between "seal" 

 and "clove"), decidedly lighter and browner than in other forms; tips 

 of wing coverts, edges of secondaries, and whole of outer tail-feathers 

 paler, more grayish, brown. Length (skin), 4.35; wing, 2.23; tail, 1.90; 

 exposed culmen 0.38; tarsus, 0.65; middle toe, 0,35. 



* The molt is nearly completedj but the longest primaries and rectrices may not 

 be fully grown.
