coloration differs a little from that of the two white birds in that 

 the black on the outermost primary extends to within 23 mm. 

 (.9 in.) of the tip, and on the third from the outermost primary to 

 within 8 mm. of the tip. It differs moreover in its smaller dimen- 

 sions and in having the culmen horn-colored instead of yellow. 

 Further collection may possibly show that this pink Phaethon is 

 worthy of taxonomic distinction.

Boobies of this species were exceedingly abundant at the island. 

 While we were passing to and from shore in the whaleboat, they 

 flew about us closely, and three immature examples were collected.

We found the Frigate Bird abundant. Numbers were seen upon 

 their nests about the summits of the smaller islets. 



6. Charadrius dominicus (Mull.)? 



A flock of seven plover, believed to have been of this species, 

 were seen repeatedly along the shore of the inlets. Unlike the 

 native birds these plover were very shy, and I could neither collect 

 one nor approach the flock closely. Fernando Noronha is doubt- 

 less a regular station for migrating shore birds, and several of the 

 authors cited above refer to Limicolae at the island.
