6 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. 
On the 12th he went to Loreto, where a day devoted to collecting 
yielded only two or three specimens each of the Titlark, Black-bellied 
Plover, and Turnstone. 
The return trip to La Paz was made in an open canoe, for the first 
half of the distance along the shores of the Peninsula, thence by way of 
San José and Espiritu Santo Islands, on both of which Mr. Frazar 
landed. He characterizes them briefly as “like the other islands,” but 
adds that the coast line of Espiritu Santo is broken in a few places by 
small inlets bordered by mangroves. It will be remembered that the 
type specimen of Belding’s Rail was obtained on this island, no doubt in 
one of the little inlets just mentioned. 
During the expedition the following water birds were noted : — 
. American Eared Grebe. Common about Carmen Island, March 6-10. 
2. Craveri’s Murrelett. On March 1 numbers were found off the west- 
ern shore of San José Island. None were seen here during the 
return trip, but on March 15 a good many were met with near the 
northern end of Espiritu Santo Island. The species was observed 
only on these two occasions. 
3. Heermann’s Gull. Two breeding colonies were visited, one on a 
small rocky island between Loreto and Carmen Island, on March 
13, the other on Montserrat Island the following day. In both 
localities the birds had only just begun laying their eggs. 
4, California Gull. A number of birds, most of them in immature 
plumage, were seen migrating northward on March 13, between 
Loreto and Carmen Island. 
5. Black-vented (?) Shearwater. Large numbers of small, dark-bodied 
Shearwaters, which probably belonged to this species, were seen 
on March 6, about midway between Montserrat and Carmen 
Islands. A few others of similar appearance were also observed 
on March 16 off the northern end of Espiritu Santo Island.’ 
6. Least (7) Petrel. A small, black Petrel seen near Espiritu Santo 
Island about the last of February must have been either this or 
the Black Petrel. 
7. Red-billed (?) Tropic Bird. A Tropic Bird noted on March 4 near 
the shore of the Peninsula, not far from Montserrat Island, prob- 
ably belonged to this species. 
8. Farallone Cormorant. About a dozen nests containing nearly full- 
grown young were found on Montserrat Island on March 14. The 
species was also seen frequently about Carmen Island.
