THE NAUTILUS. 89 



Louis, the writer remarked on p. 377, " Dr. W. H. Dall has char- 

 acterized a variety rubidum, from Cedar Keys, Florida, the shell 

 being of a deep pink color." The writer was in error in stating 

 that Dr. Dall had characterized the variety rubidum, he having 

 simply referred to the rose color. 



The history of this variety will therefore stand as follows : 



1889. Dall : Murex messorius (Sowb.) Reeve, pink variety, Bull. 

 Mus. Comp. Zool, v. 18, p. 196. 



1897. Baker: Murex messorius (Sowb.) Reeve, var. rubidum 

 " Dall," Trans. Acad. Sci., St. Louis, v. 7, p. 377. 



1900. Sowerby : Murex marcoensis, Journ. of Malocology, v. 7, 

 p. 162. 



If the two forms are the same, which I have no reason to doubt, 

 it will stand as Murex messorius var. rubidum Baker.
