DOTO PINNATIFIDA. 



original locality,— where D. coronata is not uncommon, we had come to the conclusion that it 

 was probably a variety of that species, an opinion which we now think erroneous, though the 

 two are so nearly related, that in spirits they can scarcely be distinguished from each other. 

 Doto pinnatijida, however, appears to be a good species, intermediate in its characters between 

 the two more common kinds, but possessing additional characters of its own, sufficient to 

 separate it from them. Of these, the arched veil, the slender papillose tubercles of the 

 branchiae, the profuse spotting of the black, and the row of black-tipped tubercles on the 

 sides of the body, are the most conspicuous. There cannot be a doubt that this is the 

 animal described by Montagu. We are happy, therefore, to have it in our power, before 

 the close of this work, to give figures of a species hitherto involved in so much obscurity. 



We lately obtained two specimens by the dredge in fifteen fathoms off St. Peter's Port, 

 Guernsey, adhering to the base of an Antennularia antennina.
