P. kuhl'i. (To Dr. H. Kuhl.) Cinereous Shearwater. Mediterranean Shear- 

 water. Bill scarcely or not shorter than head, equal to tarsus, moderately hooked for a 

 fihearwater, with short nasal tubes, about \ as long as culmen, but rather high for this genus, 

 with trace of a median ridge ; nostrils opening roundish ; wings folding a little beyond the tail, 

 which is graduated, with lengthened middle feathers; feet rather weak; outer toe and claw 

 longer than middle toe and claw; tip of inner claw about reaching base of middle. Upper 

 parts light smoky-gray, or pale brownish-ash, uniform on crown and nape, interrupted on back 

 by white or grayish-white edges of the feathers, especially on the scapulars, darkening on the 

 wing-coverts and tertials to grayish-brown. Rump like back ; upper tail-coverts successively 

 acquiring white till the longest ones are mostly of this color, only touched with brown. Pri- 

 maries grayish-black, with large white spaces on basal half or two-thirds of inner webs. Outer 

 webs and tips of secondaries grayish-plumbeous; most of their inner webs white. Entire 

 under parts, fi'om chin to ends of under tail-coverts, pure white, excepting some slight touches 

 of gray on the flanks ; lining of wings and axillars white, except just along the edge. On 

 sides of head and neck, no line of demarcation between color of upper and under parts, the 

 two merging through a cloudy or wavy area ; under eyelid white. Bill yellowish, dai^ker on 

 culmen and hook; feet yellowish, the webs clearer. Length about 18.00; wing 13.00; tail 

 5.50, graduated 0.75 ; chord of culmen 1.90, gape 2.60 ; height of bill at base 0.70, width 0.60 ; • 

 tarsus 1.90; middle toe and claw 2.50, outer do. 2.55. (Described from a European speci- 

 men.) N. Atlantic, European coast, especially of the Mediterranean. Greenland ? I am 

 not yet satisfied that bird really occurs on our coast. I introduced it to our Fauna in 1872. in 

 the orig. ed. of the Key, but upon strength of its general range, and Schlegel's ascription of it 

 to Greenland ; and have never seen an unquestionable N. Am. specimen. It probably occurs, 

 however. 



(addenda). P. borea'lis. (Lat. borealis, northern.) Cory's Shearwater. ''Above 

 brownish-ash, the feathers of the back becoming pale at the tips, those on the nape and sides 

 of the neck narrowly tipped with white ; on the sides of the head and neck the ash and white 

 gradually mingling as in P. kuhlii. Tips of the upper tail-coverts, white. Under eyelid, 

 white, showing clearly in contrast with the ashy-gray of the head. The first three piimaries 

 are light ash on the inner webs. Wings and tail brownish-gray. Under parts white, slightly 

 touched with ash on the flanks, lining of wings white. Under tail-coverts white, the longest 

 tinged with ash near the ends, which extend nearly to the tips of the longest tail-feathers. 

 Outside of foot greenish-black, inside and webs dull orange ; bill pale yellowish at the base, 

 shading into greenish-black, but again becoming pale near the tip. Length 20.50 inches ; 

 wing 14.50; bill (straight line to tip) 2.25; depth at base 0.75; tail 6.50; tarsus 2.20." 

 Coast of Massachusetts; several specimens now known. I copy the original description. 

 (BuU. Nutt. Club, vi, 1881, p. 84.) The bird is perfectly distinct from P. major, but very 

 near P. kuhli, if really different.
