VIII. PTYCHORAMPHUS Branpr. 1837. 
16. Cassin Auklet. 
Ptychoramphus aleuticus (PALL.) BRANDT. 1837. 
Pacific coast of North America from the Aleutian islands to 
Lat. 49°. (A. O. U. List.) Breeds on the Aleutian islands and is 
rather common on some of them. (Zurner.) This species was 
seen in the Gulf of Georgia between Salt Spring island and 
Nanaimo and one shot May 7, 1887. (Macoun.) Seen in numbers 
and one shot on Queen Charlotte sound. (Dr. G. M. Dawson.) 
IX. CYCLORRHYNCHUS Kavp. 1829. 
17. Paroquet Auklet. 
Cyclorrhynchus psittaculus (PALL.) STEJN. 1884 
A single adult male was taken at Sitka, Alaska, June 8th, 1897, 
by Mr. Frobese and presented to me. It was the only one seen, 
( Grinnell.) 
This species is extremely common in Bering strait and south- 
ward through the whole length of the Aleutian islands as well as 
on the Pribilof islands, St. Matthew and St. Lawrence islands. 
(Nelson,) Abundant on the Aleutian islands, and breeds in ail 
suitable places. (Zurner.) Common on the Pribilof islands. 
(J. M. Macoun.) 
BreEDING NotEs.—It comes to the Pribilof islands early in 
May, mute and silent, locating its nest ina deep chink or crevice 
of some inaccessible cliff, where 1t lays a single egg, of a pure 
white colour and oblong-ovate in shape, on the bare rock or earth. 
(Elhott.) On Walrus island they lay their solitary egg under the 
boulders like the puffins. The burrows on St. Paul island, as far 
as I saw, were excavated in the volcanic cinders overlying the 
rocky bluffs so that the entrance was always at the edge of the 
cliff with the rock as a floor. (Palmer.)
