bill. It is otherwise a normal hypoleucus.^'' The tarsi of 

 this specimen are scutellate in front — as distinctly scu- 

 tellate as in Synthltboramphus antiquiis. This record ap- 

 parently extends the known range of this species, for I 

 find no mention in the general literature of its occurrence 

 so far north. 



Cepphus columba. Pigeon Guillemot. — This species 

 was rather common at Monterey Bay upon my arrival. It 

 increased in abundance, with the progress of the migra- 

 tions. A breeding colony was apparently established on 

 the south side of Carmel Bay at the time of my visit, 

 June 25th, for fifty or more adults suddenly appeared 

 from the water's edge of the rocky islets along the shore 

 when I fired my gun. Before not one had been in sight. 

 A party of Stanford University students found a nest with 

 young the day following in the same locality. 



Uria troile calif ornica. California Murre. — Al- 

 though a common bird during the latter half of June, the 

 California Murre was apparently only a migrant in the 

 vicinity of Monterey in summer. As has already been 

 stated, young birds, unable to fly and under the care of 

 adults, appeared early in August, probably from a rook- 

 ery somewhere in the vicinity of Pt. Santa Cruz. These 

 young birds were expert divers. When an adult and its 

 charge were approached, the young bird would dive 

 first. If the two became separated, the old one would 

 call loudly, and as soon as the young responded the 

 old bird would dive, coming to the sui'face at the spot 

 where the young one had taken refuge. I shot an adult, 

 and quite unexpectedly it proved to be a male. Cali- 

 fornia Murres, on being approached, have a curious 

 habit of frequently dipping their bills into the water. 

 They also have the habit of standing erect on the water
