16. Larus leucopterus Faber. Iceland gull. 
Eskimo: Nowyah . 
This species is so scarce about Baffin island that the only evidence of 
its existence secured by the writer is an adult and a juvenile, collected 
August 18, 1924, near Blacklead island, Cumberland sound. Kumlien 
(1879, p. 98) merely remarks that it is far less common in Cumberland 
sound than the glaucous gull. This species was not noted by Hantzsch. 
17. Larus kumlieni Brewster, kumlien gull. 
Eskimo: Nowyah. 
This bird, found by Kumlien in 1878, in Cumberland sound, was at 
first, referred to glaucescens, but afterwards was recognized to be a new 
species. So far as known, it does not extend on Baffin island, north of 
Cumberland sound. 
A specimen was taken on August 18, 1924, near Blacklead island, and 
is the only evidence secured by the writer of the existence of the species in 
Cumberland sound. It was found common in late June, 1926, on some of 
the islands of Fox group in Gordon bay on the south coast of Baffin island. 
Six specimens were collected on June 20, 21, and 27 in this locality. It 
was found nesting on one of the islands, sharing the same cliff with the 
herring and glaucous gulls. On an island a short distance west of cape 
Dorset a colony of about one hundred was seen on July 24, 1926. They 
occupied ledges on a sheer cliff overlooking the sea; the ledges were not 
shared with any other species of gull. 
Regarding this species Kumlien (1879, p. 98) says: 
"So far as I am aware this is the first instance on record of this bird being taken on 
the Atlantic coast. They are quite common in the upper Cumberland waters, where 
they breed. Arrived with the opening of the water and soon began nesting. The nest 
was placed on the shelving rocks on high cliffs.” 
A specimen referred to kumlieni was collected by Burwash in the 
summer of 1924 at cape Dorset. This species was not noted by Hantzsch. 
18. Larus marinus Linnaeus, great black-backed gull. 
A rare gull on Baffin island. It was not observed by the writer. 
Kumlien (1879, p. 99) remarks that it is observed in Cumberland sound 
only in late autumn. Low (1906, p. 316) says that a large colony was 
seen on the high cliffs of Cuming creek, Devon, and in other inaccessible 
places on the northern islands. This species was not noted by Hantzsch. 
The species is probably to be expected in at least the northern regions 
of Baffin island. It was not seen north of the St. Lawrence on the Canadian 
Arctic Expedition of 1923. 
19. Larus argentatus Pontoppidan. herring gull. Larus thayeri Brooks, thayer 
gull. 
Eskimo: Nowyah; Tessilmenta. 
Specimens collected by the writer indicate that Larus thayeri is confined 
to a northern area extending from Ponds inlet to southern Ellesmere island, 
and that L. argentatus occurs only in the southern part of Baffin island. 
Larus thayeri was observed only while on the 1923 Canadian 
Arctic Expedition when specimens were collected at Craig harbour, Elles- 
mere island; Beechey island; Dundas harbour, Devon island; and Ponds 
inlet, Baffin island. The species seemed to be particularly numerous in
