NUDIBRANCHIATA OF THE UL.M.B.C. DISTRICT. 105 
This species is very variable both in colour and in form 
in this district. In some of these specimens* the dorsal 
papille have not the usual tuberculated appearance, but 
are merely irregularly rounded or slightly lobed. One 
specimen had the third papilla of the left side distinctly 
bifurcated, the central vessel giving off a branch into each 
of the forks. In some cases a few of the dorsal papille, 
besides the terminal pair, are of very small size. 
A specimen of Doto coronata, found on a Compound 
Ascidian from the shore at Puffin Island, has the tubercles 
of the dorsal papille slender and tipped with black spots 
so as to approach the character of Doto pinnatifida. 
Alder and Hancock figure the radula of Doto fragilis 
(pl. xlvu., supplementary) alone, and state that that of 
D. coronata is “like D. fragilis, but rather more distinctly 
denticulated at the sides’’ (loc. cit.). We find, however, 
in our specimens of D. coronata that the plates of the 
radula are not denticulated at the sides. 
Doto fragilis, Forbes. 
We dredged this species on 24th March, 1888, in the 
Turbot Hole, off the N.E. end of Puffin Island, and also 
brought up a specimen on a long line set for fish off the 
rocks immediately below the Biological Station.

This species has been taken in January, March and 
April, on the South Spit at Puffin Island. We have also 
found a very light coloured variety in shore pools at 
Fleshwick Bay, Isle of Man.
