Dr. BovALLius shot at Bayoneta two Man-o' -war- 

 birds, which for some time throiigh their shyness had baffled 

 his endeavours to come within range of them. 



At the little rocky holm C a n g r e j o north of San 

 Miguel several hundreds of these birds had their breeding- 

 places. 



Fam. Pelecanidae. 

 4. Pelecanus califoriiicus (Ridgway). 



I find no records in the literature about the occurrence 

 of the Cahfornia Brown Pehcan in the Las Perlas Archipelago. 



Dr. BovALLius found this bird abundant in P a c h e c a. 

 At his visit in the last days of March there were young ones 

 in the nests. Above I ha ve already given an account of the 

 bird-life in that island. According to the mentioned division 

 of the space between the species, the Pelicans inhabited the 

 outermost trees on the börder of the plateau. 



The nests were relatively small and when occupied by 

 the female and two nearly full-fledged young ones they squeez- 

 ed together because of lack of space. 



Following the example of the Cormorants, great flocks of 

 Pelicans from the adjacent islets met at the southern shore of 

 Bayoneta, where they did not breed. Dr. B. states, that 

 he at a time saw several thousand Pelicans leisurely swimming 

 in a large cove, until this at low tide was drained, when a 

 voracious revelling took place. Egrets, which approached, 

 were immediately driven away. After the demolished meal 

 the Pelicans with heavy wingstrokes flew southward to the 

 islets north of Pedro Gonzalez. 



Hundreds of these birds bred on S e n n o r a in the mostly 

 leafless trees on the ridge of the rocky islet. Each nest con- 

 tained 2 — 4 nearly full-fledged young ones. 



On Punta Cocos, the southern point of San Miguel, 

 the Brown Pelican was very common at low tide. 



In San E 1 m o it was a common inhabitant. 



In the collections of the State Museum I found one skin 

 of this species, which, judging by the way it was prepared, 

 was supposed to have been brought by Dr. Bovallius. It 

 is unfortunately unlabelled.
