a few straws. The single egg, taken by Stephens, July 16, was 
incubated to an advanced degree. The shell is dirty white and 
apparently entirely unmarked, this being exceptional with this 
species. It is ovate and measures 72.5 & 49.6. A chick was 
secured on the same date. Dixon obtained a chick on a small 
island near Coppermine Cove, July 17, and found the species 
breeding on South Marble Island, July 5. Both these points are 
in Glacier Bay, and the tufted puffin was found by the expedition 
nowhere else in the region explored. 
Fratercula corniculata (Naumann). Horned Puffin. 
Two adult males (Nos. 83-84) were secured by Dixon at 
South Marble Island, Glacier Bay, July 5. They were the only 
individuals of the species observed there. An eg@ was seen in 
a burrow on that island but it could not be reached. Littlejohn 
later in July noted a very few horned puffins out in the open 
bay among the drifting ice. 
Ptychoramphus aleuticus (Pallas). Cassin Auklet. 
Mr. Littlejohn feels sure that he saw several of this species 
from the launch, while crossing Icy Strait just before entering 
Glacier Bay, June 27. 
Synthliboramphus antiquus (Gmelin). Ancient Murrelet. 
The only example of this species obtained by the expedition 
was shot by Dixon near Coppermine Cove, Glacier Bay, July 17. 
The specimen is a male (No. 85) in some immature plumage 
and may be described as follows: The whole lower surface is 
white, except extreme chin and sides under the wings which are 
ashy; whole dorsal surface slate-gray, becoming slate-black on 
top of head, wings and tail; a narrow region on each side from 
above the eye back towards nape flecked sparsely with very 
slender white plumes; upper and lower eyelids white. No eal- 
eareous nodules on bill. 
Brachyramphus marmoratus (Gmelin). Marbled Murrelet. 
Almost everywhere that collecting was carried on by the ex- 
pedition and throughout the season, the marbled murrelet proved 
common; yet no clue was found as to the location of its breeding
