DOTO CORONATA. 



no other species be found agreeing better with the description and figure, the occurrence 

 of D. coronata on that part of the Devonshire coast may afford a fair presumption of its 

 identity with the long lost Doris pinnatifida. 



Another of Montagu's species, referrible to this genus, stands in a somewhat similar pre- 

 dicament; namely, Boris maculata, which agrees with the present species in the form, 

 colour, and markings of the body, but differs in the branchiae being much smaller and with 

 only one whorl of tubercles. We have occasionally found D. coronata with one or two of 

 the processes of a similar form to this, either from the individuals being young, or from new 

 branchiae being in process of reproduction where others had fallen off. We have never met 

 with an individual with all the branchiae in this state, but the possibility of such an occur- 

 rence induces us to look upon this species also with some suspicion. 



A more complete examination of the species on the southern coast is very desirable.
