Our specimens do not agree in all respects with Yerrill's descrip- 

 tion, and at first it seemed necessary to refer them to a new species ; 

 comparison with specimens received from him has established their 

 identity. Verrill ascribes four eyes to S. vlHdis / our specimens 

 have no eyes, as they were examined in this respect in the fresh 

 state ; the alcoholic specimens received from Prof. Verrill have no 

 trace of eyes remaining, whatever their condition may have been 

 while living. We found but one green specimen ; the others were 

 dark brown, or dark brown with a reddish or greenish tinge. There 

 are from eight to ten anal papillte (cirri), subulate, three to four 

 times as long as the anal segment.
