136 NORTH AMERICAN BIRDS. 



laiyor, tliouGih it is hut just to say tliat it is a foiualo ; tlio wing measures 

 l:').!*.'), iustoad of VlJtO, and tlio niidtlle toe, 2.011, instead of 1.85. No. 

 37,:5.'JO, Ties Marias Islands, Western Mexieo, — a young male in second 

 year, — lias tlie wing just the same leiigtli as in the smallest Nortli American 

 e.\ami)le, while in ])lumage it is ])re('isely similar to 2(1,780, of the .same age, 

 from Jamaica. No. 4,c)()7, from I'uget's Sound, Washington Territory, — also 

 a young male, — has the wing of the same length as in the largest northern 

 specimen, while the plumage is as usual. 



Two adult females from Connecticut (Nos. 28,09'J and :i2,5()7, Talcott Mt.) 

 are remarkable for their very deej) colors, in which they diil'er from all other 

 North American examples which I have seen, and answer in every jiarticular 

 to the tlescription of /'. ciitistni, Sharpe, above cited. The upper surface is 

 plumbeous-black, becomii.g deep black anteriorly, the head without a single 

 light feather in the black portions ; the plumbeous bars are distinct only on 

 the rump, upper tail-coverts, and tail, and are just perceiitible on the secon- 

 daries. The lower parts are of a very deep reddi.sh-ochraceous, deepest on the 

 breast and abdomen, where it ai>i)roaches a cinnamon tint, — the markings, 

 however, as in other examples. They measure, wing, 147") ; tail, 7.50 ; cul- 

 inen, 1.05 - 1.15 ; tarsus, 2.00 ; middle toe, 2.30. They were ol)tained from 

 the nest, aiul kei)t in confinement three years, when they were sacrificed to 

 science. The unusual size of the bill of these si)ecimens (see measurements) 

 is undoubtedly due to the influence of confinement, or the result of a modi- 

 fied mode of feeding. The specimens were presented l)y Dr. S. S. Moses, of 

 Hartford. 



An adult male (No. 8,501) from Shoal-water Bay, Washington Territory, 

 is exactly of tlie size of the male described. In this specimen there is not 

 the slightest creamy tinge beneath, while the blue tinge on the lower ])arts 

 laterally and posteriorly is very strong. No. 52,818, an adult female from 

 !Mazatlan, Western Mexico, has the wing three quarters of an inch shorter 

 than in the largest of four northern females, and of the same length as in the 

 smallest ; there is nothing unusual about its plumage, except that the bars 

 beneath are s])arse, and the ochraceous tinge (piite deep. No. 27,057, Fort 

 Good Hope, H. 15. T.. is, however, exactly similar, in these respects, and the 

 wing is but half an inch longer. In No. 47,588, <? ,from the Farallones Islands, 

 near San Francisco, California, the wing is the same length as in the average 

 of northern and eastern specimens, w-hile the streaks on thejugulum are 

 nearly as conspicuous fis in a male from Eurojie. 



In conclusion, I would say that the sole distinguishing character between 

 the Peregrines fnjm America and those from Eurojie, that can be relied on, 

 appears to be found in the markings on the breast in the adult jdumage ; 

 in all the specimens and figures of var. communis that I have seen, the 

 breast has the longitudinal dashes very conspicuous ; while, as a general 

 rule, in anutiim these markings are entirely absent, though sometimes 

 present, and occasionally nearly as distinct as iu European examples. There-
