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 Jose 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 : — 



1. 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 Jose 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 j\Iarch 

 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 (X) Shearwater. Large numbers of small, dark-bodied 



Shearwaters, which probably belonged to this species, were seen 

 on March 6, about midway between IMontserrat 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 (1) 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.
