Vor. IIT] BECK—CALIFORNIA WATER BIRDS 59 
black-throated relatives; the majority appear to depart about a 
month earlier in spring. It is decidedly common at times. 
9. Lunda cirrhata. Turrep Purrin.—Neither Mr. Loomis 
nor myself have observed the “Sea Parrot” in this immediate 
vicinity during January, February, March, and April. Accord- 
ing to our observations it is a rather common visitant at 
intervals during the rest of the year. 
10. Cerorhinca monocerata. RHINOCEROS AUKLET.—So far 
as I am aware, the earliest and latest occurrences in this 
vicinity are September 27 and the middle of May. It is a 
common winter bird; in 1907 it was numerous as early as 
October 14. 
11. Ptychoramphus aleuticus. Cassin’s AUKLET.—Although 
there are no breeding places in the immediate neighborhood of 
Point Pinos, individuals occur in the height of the breeding 
season. Early in August there are inroads from breeding 
resorts. Asa winter bird it is common, though perhaps vary- 
ing in numbers in different years. 
12. Phaleris psittaculas PAroguet AUKLET—TIn January, 
1905, one was taken on the 14th and two on the 17th; all were 
several miles offshore. In January, 1908, twelve were captured 
on the 13th, one on the 15th, and one on the 30th. All were 
found several miles from shore. A dead one was picked up 
on the bath-house beach at Pacific Grove on the 28th. 
13. Synthliboramphus antiquus. ANCIENT MurreLet.—That 
the experience of Mr. Loomis in finding this boreal auk com- 
mon in December, 1894, and January, 1895, was not excep- 
tional, is proved by my own observations. The species is 
certainly a common winter one. In 1907, the first seen were 
six on October 21; by the middle of November they had 
become common. In 1909, two were shot on September 2Z. 
Three stragglers were noted March 22, 1907. 
14. Brachyramphus marmoratus. MarsLepD MuRRELET.—A 
striking instance of variation in abundance and times of occur- 
rence is furnished in this species. Flights of adults similar to 
those noted by Mr. Loomis at the end of July and in August, 
1894, were not witnessed by me. Mr. Loomis found these 
birds common in the midwinter of 1894-1895, while I found 
them scarce in the midwinter of 1904-1905. In 1907, during 
the last of February and through March these murrelets were 
passing north, usually in pairs. A straggler was seen on April
