broadly tipped with tlie same, and (nsnally) with more or less of whitespot- 

 tiug- near the base on the outer webs ; inner webs of middle pair of tail- 

 feathers usually more or less marked with white (very rarely solid black) ; 

 outer rectrices hoary drab on the under surface, the outer edge indented 

 with small white spots, or indications of bars, the end portion of the 

 inner webs usually with one or more white bars (sometimes with none). 

 Adult 9 : Similar to the i , but entire pileum light ash-gray, becoming- 

 lighter anteriorly; nape varying from bright safiron-yellow to scarlet, 

 with scarcely a tinge of orange. Young i : Similar to the adult, but all 

 the markings much less distinct, and the colors duller. Bill black; iris 

 bright red; feet olive-greenish. (MS. notes on labels.) Wing, 5.00-5.75; 

 tail, 3.10-1.00; culmen, .95-1.25; tarsus, .90-1.00. 



Whether the present form is to be regarded as a distinct species or 

 not, there can be no question that it grades directly into three other forms, 

 viz, C. aurifrons, C. dubius, and C. lioffmanni. In its typical condition, how- 

 ever, it is a very strongly characterized race. Among- the large series 

 of specimens now before me, many striking- variations from the normal 

 type are observable; some of them tending to one or the other of the 

 above-named races, others quite unique in their characteristic features. In 

 most of the adult males, the red of the nape is entirely continuous with 

 that of the crown; but in some (as in Ko. 57834, Sta. Efigenia, Isth. 

 Tehuautepec, Jan. 10, 1809, F. Sumichrast, and 27955, Mirador, C Sar- 

 torius), the occiput is crossed by a band of ash-gray, almost completely 

 separating the two bright-colored areas. In the former of the above 

 specimens, the head is colored throughout exactly as in some examples 

 of pure C. aurifrons, the nape being bright orange, markedly different 

 from the deei^ red of the crown, and barely connected with it along the 

 median line ; but the lower parts are of a deep olivaceous drab, the ab- 

 domen deep saffron, and the posterior parts densely barred, as in typical 

 santacruzi. The upper parts are more broadly banded with white than 

 in true santacruzi, but less widely than in either aurifrons or lioffmanni. 

 A near approach to the latter form is seen in the broad and distinct 

 white bars (about 7 in number) on the inner webs of the middle rectrices, 

 the outer webs of which are marked with a long narrow white stripe; 

 but the size is much greater, the dimensions fully equalling the maxi- 

 mum of aurifrons (wing 5.G0, tail 4.10, culmen 1.25). The Mirador speci- 

 men is evidently a young bird, and has the inner webs of the middle 

 rectrices chiefly occupied by a large longitudinal blotch of white. An- 

 other adult male from the Isthmus of Tehuautepec (Xo. 57830, Chihuitan, 

 ]Si"ov. 20, 1868, r. Sumichrast) is in all respects like the one described, 

 except that the nape is deej) orange-red, and this color more comi)letely 

 coalesced with the crimson of the crown. It is also equally large (wing^ 

 5.70 tail, 4.00, culmen 1.12). C.iwhjgrammus, of Cabanis, appears to have 

 been based upon specimens representing this style. Adult females from 

 the Isthmus of Tehuautepec agree with the males in the broadness of the 

 white bars of the dorsal surface, and the white markings of the middle
