feathers of head ; dark under and partially white upper tail-coverts. Length 18.00-20.00; ex- 

 tent 42.00-45.00; wing about 13.00; tail 5.75, graduated 1.00; tarsus 2.40; middle toe and 

 claw 2.90; outer ditto 2.75 ; inner ditto 2.30; chord of cuhneu 2.00; depth of bill at base 0.65, 

 width 0.60. Wanders over the whole Atlantic, Greenland to Cape Horn and Cape of Good 

 Hope ; abundant in summer off the coast of New England. Sometimes seen in flocks of thou- 

 sands, shearing the crests of the waves, and skimming the billows with marvellous ease, with- 

 out a visible motion of the pinions. It is a very well known bird, yet its breeding-resorts are 

 much of a mystery. P. major of former editions of the Key, as of most authors. P. cinereus

P. creat'opus. (Gr. Kpiai., kreas, flesh ; novs, pons, foot.) PiNK-FOOTED Shearwater, 

 Bill short, less than head or tarsus, turgid at base, where as wide as high. Nasal tubes short, 

 hardly ^ the length of culmeu, turgid, with slight median furrow and very oblique truncation. 

 Frontal feathers running forward on median line. Form otherwise as in P. gravis. Adult : Bill 

 pale yellowish flesh-color; nasal tubes, culmen, and tip blackish. Feet flesh -colored; claws 

 whitish with brown ends. Upper parts about the same shade of brown as in P. gravis; upper 

 tail-coverts entirely dark. No white on inner webs of primaries. On sides of head and neck 

 the color of the upper parts extends entirely around, without any distinct line of demarcation ; 

 chin and throat mottled with dark and white in about equal amounts. On sides of breast the 

 color more restricted than on neck. Lower eyelid white. Sides of body and lining of wings 

 mottled with dusky and white in about equal amounts ; long axillars dark except just at base. 

 Middle of belly and vent variegated with dusky and white. Under tail-coverts entirely fuligi- 

 nous. "Length 19.00; extent 45.00;" wing 12.50; tail 5.00, graduated 1.00; tarsus 2.10; 

 outer toe and claw 2.50; middle ditto 2.65 ; inner ditto 2.60; chord of culmen 1.60 ; gape 2. '30; 

 height or widtli of bill at base 0.60; nasal tubes 0.40. Eastern Pacific Ocean; coast of 

 California, S. to Chile. 



P. puf'finus. Manx Shearwater. "Puffin of the Isle of Man." Smaller and otherwise 

 very different from any of the foregoing. Adult : Upper parts uniform lustrous black, or black- 

 ish with slight brown or slaty shade, rather ashy across hind neck ; the dark color extending 

 on sides of head nmch below eyes, but there marbled with white ; under eyelid wliite, set in 

 black. On sides of neck the white reaches part way around ; on sides of breast the dark extends 

 some distance, dilute and marbled with white. Primaries black, with black shafts, their inner 

 webs dull gray isli -brown; tail-feathers like primaries. Entire under parts, from chin to anus, 

 pure white, exce{)t a few feathers of the flanks, and outer webs of outer under tail-coverts, 

 which are plumbeous-black. Lining of wini^.^ and axillars white, mottled with black along the 

 edge. Length 13..")0-]5.00; extent 30.00-33.00; wing 8.75-9.25; tail 3.10, graduated 0.75 

 or less; tarsusl.80; middle toe and claw 1.90; outer ditto 2.00; inner ditto 1.55; chord of cul- 

 men 1.40; gape 2.10; height or width of bill at base 0.45. Varies much, but the small size 

 and blackishness are distinctive. Chiefly inhabits the Atlantic coast of Europe, and the Medi- 

 terranean ; it is the most numerous British species of the genus, said to range the N. Atlantic 

 at large, S. to Brazil ; but those who ^<uppose it to be a common North American species are 

 mistaken. Nest in burrows in the ground dug by the birds, or in natural cavities; egg single, 

 dead white, smooth, 2.35 X 1-60. Nestlings in down sooty-gray above, whitish below.
