Arctic Seas to Lower California. 



This species was originally described from specimens and notes obtained by me at Monterey, 

 California, in January, 1866, and now in the Mus. S. I. A peculiar barnacle, Gryplolepas rhachi- 

 anecii, Dall (pi. x, fig. 6), and the Gi/amus Scammoni, Dall, (pi. x, fig. 1), appear to be restricted 

 to this species. They are described in the Proc. Cal. Acad. Sci. 1872, vol. iv, pp. 281, 300. A 

 skull collected by me at Monterey, California, is now in the collection of the Cal. Acad. Sci., and 

 another in Mus. S. I.
