JOURNAL OF MAMMALOGY 
The action of the ice on these islands seems inconsequential. No 
worn pebbles were found back of the beaches nor are glaciers present. 
Snow probably remains most of the summer in some of the canyons, 
since it was very deep in places in early July. 
LIST OF MAMMALS 
Whales . — The vicinity of St. Matthew Island has long been known for the 
abundance of whales at certain seasons. The great numbers of bones of these 
animals on the beaches, as compared with such islands as the Pribilofs, is an 
indication of their relative abundance. The conditions attending this investi- 
gation prevented the collection of a series of specimens of the several species 
identified on the beaches, and the positive determination of some of the kinds 
which may be represented there and in the surrounding waters. 
Balaena mysticetus. Bowhead Whale. — The bones of this species are ex- 
ceedingly abundant on all beaches. A pair of mandibles 19 feet long were found 
in the center of the long north shore beach and vertebrae by the hundred were 
observed; some were far back of the high tide mark, half buried in the tundra, 
and others showed fresh and white among the drift logs. Two skeletons lay 
bleaching on the south shore abreast of Pinnacle Island. 
Balaenoptera velifera. Humpback Whale. — A skeleton of this species lies 
scattered on the south side of the spit connecting Cape Upright with the main 
portion of St. Matthew. The longest pieces of baleen were about four feet. 
Sibbaldus sulfureus. Sulphur-bottom Whale. — A skull with baleen of this 
species was found on the spit connecting Cape Upright with the main island. 
Orcinus orca. Killer Whale. — Bones of a killer were noted in two places on 
St. Matthew, those most recent being on the north shore near the center of the 
island. 
Berardius bairdii. Baird’s Whale. — A carcass of this rare ziphoid had washed 
into the lagoon on the south side of St. Matthew Island, two miles below 
Cape Glory of Russia. The skull was in good condition but rough weather pre- 
, vented the taking of a boat around to the place, and it could not be carried across 
the bogs to the other side. A periotic bone was preserved however and the 
identification verified by True’s excellent work on this family (Bull. 73, U. S. 
Nat. Mus.). This specimen seems to mark the known northern range of the 
species. 
Phoca sp. Hair Seal. — A colony of hair seals was found by Captain Dodge 
July 8 on an outlying rock abreast of Waterfall Head, but no specimens were 
secured. From the number of young observed he was led to believe the place a 
breeding rookery. Another lot was seen on the north shore near Cape Glory of 
Russia but all shots miscarried and efforts to collect good specimens were unsuc- 
cessful. Two imperfect skulls were found on the beaches and they represent 
two species. 
Odobenus divergens. Walrus. — A herd of about 500 was seen near the middle 
of the north shore, cruising along with the ship. Walrus skulls were common on 
the beaches and the officers and men found several pieces of ivory. They haul 
out on the northwest cape of Hall Island under the high cliffs, so I am told by
