their primary-quills and tail-feathers are concerned, but 
apparently not otherwise. Some of their primaries are only 
three inches long. 
The ‘Gauss’ obtained a Tern off Kaiser Wilhelm II. 
Land, in 66° S., 89° 38’ E., on February 18th, 1903, which 
Reichenow (Orn. Monatsber. xi. p. 47) described as a new 
subspecies of the Arctic Tern under the name of Slerna 
macrura antistropha. This is said to be “ very hke S. ma- 
crura, but with the bill darker, not cinnabar or poppy-red, 
but carmine at the base and blackish towards the tip ; lower 
edge of mandible longer, 21-22 mm., in macrura only 
16-19 mm. Feet not yellowish red to cinnabar-red, but 
dusky carmine-red, webs blackish. Tarsus somewhat longer, 
15-17 mm.” If described from skins, that fact might account 
for the subtle differences in colour, or if such differences 
really exist they might be due to the season (the winter for 
S. macrura). The ‘Scotia’ specimens do not exhibit the 
peculiarities attributed to this subspecific form, except that 
one of them agrees with it so far as the dimensions of the 
mandible and tarsus are concerned.

No Gulls were observed during the Antarctic voyages of 
the ‘ Scotia,’ except Larus dominicanus in the vicinity of the 
South Orkneys. In the ‘ Antarctic Manual’ (p. 282) it is 
stated that this Gull was obtained in 64° 18’ S., and that a 
specimen of Larus scoresbyi, also in the British Museum, 
was obtained in the vicinity of the South Shetlands in 
64° 55'S. Mr. Bruce, who was naturalist on the ‘ Balena,’ 
from which vessel the birds in question were obtained, tells 
me that these examples were undoubtedly captured at the 
Falkland Islands and that they were skinned by him. |
