mandible being without Gnathidie, and formed, as it were, 
of a single plate doubled together, the ridge or culmen, in 
the adults, presenting no appearance of suture. The’ base 
of the upper mandible is also on the same line with the fore- 
head, the latter having no antiz ; and the nostrils are situat- 
ed on the lower part of the smooth space of the beak, imme- 
diately in front of the basilar ridge. These birds are inha- 
bitants of the arctic circle, penetrating to rather high lati- 
tudes ; and in their habits and mode of life, bearing a strong 
resemblance to the preceding genera. They breed in bur- 
rows, or under hollow stones, and lay one egg. Nearly al- 
lied to this genus, and intermediate between it and the Auks, 
is the genus Phalarzs of 'TEMMINCK, containing several spe- 
cies which were also formerly included in the Linnean genus 
Alca.
