178 Notes from the Gatty Marine Laboratory. 



This species closely approaches StheneJais Jeffrey sii^ McE., 

 but the marked characters of the bristles of the ventral 

 division of the foot distinguish it, and once more demon- 

 strate, what some are so slow to admit, the value of a careful 

 study of these organs along with other characters. Step by 

 step the differentiation is thus made clear. Dr. Appellof 

 probably refers to this species in the list before mentioned 

 under the name S. Jeffreysii, and, indeed, it would have 

 been difficult for him to distinguish them.
