collected them by the thousand, and compared the animals of 

 the varieties. The animal is of a uniform light slate-color, with 

 very black tentacles. With this table of synonyms no remarks 

 are called for with reference to its being a variety of viridans 

 Mighels.

The fine large white variety described by Mr. Gulick, first 

 suggested the name of variabilis for this variable species. 



I omit the description of the animal of this and many other 

 species as having no practical importance in this connexion.

Animal, when in motion, longer than the shell ; rather slen- 

 der ; base of foot light yellow ; upper and anterior portion of 

 body and tentacles slate ; sides and mantle of a light flesh 

 color ; movements lively. 



Mr. Gulick has thought these varieties worthy of specific 

 names and descriptions. While believing that he refines too 

 closely for practical or scientific purposes, I wish to award him 

 the merit of close application, and a just appreciation of the 

 merits of this beautiful study.
