414 W. C. M'INTOSH ON THE ANNELIDA 



the name of Audouin and M. Edwards : those having the original and other closely 

 allied forms will easily discriminate. It is distinguished from Claparede's Lepido- 

 pleurus by the fact, amongst others, that the latter has no eyes, and every foot is sup- 

 plied with scales, whereas in this the scales are chiefly alternate. No other species of 

 Fsammolyce seems to approach it.
