104 THE NAUTILUS. 



Pourtalesii Dall=not found in U . S. 

 Splendens Reeve=^fulgens Phil. 



Notes. 



1. H. Pourtalesii Dall. Bull. Mus. Comp. Zool. xviii, 395, is said to have been dredged [one 

 specimen] in 200 fathoms, near Florida Reefs, by Pourtales, in I869, but as the specimen was de- 

 stroyed in the great Chicago fire, and none has been found since, we may dismiss it from the list 

 of United States species, especially as no other specimen or species of Haliotis is known to have 

 been found on the East Coast of America. 



2. It seems to us a pity that H. fulgens Phil, should be substituted for the well known and 

 generally used name of H. splendens Reeve. The law of priority of description should give way 

 in exceptional cases of merit, but as Mr. Pilsbry in Tryon's Manual has made the substitution, 

 and some of the specialists to whom we have written agree with him, it is perhaps as well to ac- 

 cede to the change, so as to have the name of the shell settled. 



3. A fine series of shells in the Academy collection, seems to prove that Haliotis Kamtschat- 

 kana Jonas passes imperceptibly into Haliotis gigantea Chemn. The home of the species is 

 Japan, and it reaches its highest development there, extending northward around the Coast of 

 Asia to the West Coast of America and reaching as far south as Monterey, Cal. getting smaller 

 in proportion to its distance from Japan. We see no reason for making it a variety. 



4. Mr. Henry Hemphill of San Diego, Cal. says of Haliotis assimilis Dall : " It has a certain 

 aspect of its own. Its habits are different from any of the other forms, being a deep-water and 

 not a littoral shell, while all the other Haliotis are found between tides. I have always considered 

 it a hybrid between H. corrugata and H. splendens, on account of its having an intermediate 

 aspect about it.
