UI PROCELLARIIDAE 67 
have each been recorded once. The latter breeds on mountain- 
tops in islands, and of its other congeners some at least do like- 
wise, many having an extremely limited range at all seasons. 
Priofinus cinereus, the “ Night-hawk,” perhaps more noisy at 
night than even certain Shearwaters, is greyish-brown above and 
white below; it inhabits the southern oceans. Thalassaeca 
anturetica, restricted to the Antarctic regions, is brown with 
white lower parts and some white on the wing, tail, and their 
coverts. Priocella glacialoides of the southern seas, which ranges 
northwards to Washington State in the Pacific, and seems to 
have the habits of a Fulmar, resembles that bird in its pearl- 
grey hue, with nearly white head, neck, and under surtace. 
Majaqueus aequinoctialis of the regions south of lat. 30° S.. 
known as the “ Cape Hen,” is sooty-black with a white chin, J/ 
parkinsoni of New Zealand being uniform in tint. The cry is 
a soft whistle, but the manners are in other respects as in Shear- 
waters, except that a conical nest is constructed in a burrow, 
whence a curious cackling noise issues during the period of 
incubation.’ Pagodroma nivea, of the icy regions of the south, is 
pure white with black bill and yellowish feet; it remains on 
the wing until late at night, and resembles Prion generally in its 
ways. Bulweria bulwert, met with once in England, inhabits the 
temperate parts of the North Atlantic and the North Pacific, and 
breeds as near us as the Desertas; it is almost uniform sooty- 
brown, and has the habits of a Storm-Petrel rather than of a 
Shearwater, being bold but wary, and rapid in flight, with a loud, 
cheerful quadruple note. It lays its pure white eggs without any 
nest in crevices of rocks, breeding as late as June near Madeira. 
B. macgillivray?, with stouter bill, is known from the Fijian waters. 
Our third group includes the true Storm-Petrels (Procellaria) 
and their close allies the Fork-tailed Petrels (Oceanodrom«a), as 
well as Halocyptena microsoma, a dark blackish bird from 
Western America, between California and Panama. P. pelagica 
of the Mediterranean and North Atlantic from Greenland to 
South Africa, which breeds in Scotland, Ireland, and the West of 
England, is sooty-black with the tail-coverts white, except at 
the tips, and a little white on the wing-coverts. Named 
“Mother Carey’s Chicken” by sailors, who look upon it with 
superstitious dread, it is often seen paddling along the waves in
