DALL: MOLLUSCA AND BRACHIOPODA. 435 
This has a general similarity to M. bicarinata Smith and M. paucistriata Dall, 
of the Indian Ocean and Atlantic, but differs in details of sculpture. It is named 
in honor of the late commander of the “ Albatross,” who was unfortunately lost 
Overboard during heavy weather, near the Hawaiian Islands. 
Notes on the Littoral Species. 
Since the distribution of species upon islands is a matter of interest I add the 
following lists of littoral or beach shells collected by the ** Albatross,” party during 
Visits to the islands in the Bay of Panama, to Malpelo and Cocos Islands, Manga 
Reva in the Paumotu group, and especially to Easter Island, which, from its iso- 
lated position as the most eastern outpost of the Polynesian arehipelago, is seldom 
Visited, and I believe has never been visited with the purpose of studying the 
Molluscan fauna. 
I may add that some slugs collected on the shore at Easter Island and sub. 
mitted to Dr. H. A. Pilsbry were reported by him to be the ordinary European spe- 
Cles, Limax gagates, probably introduced in the packing about freight consigned to 
local traders,
