86 dorididjE. 



Habitat : On rocky shores and in shallow water, on nearly 

 all parts of the English and Scottish coasts, but nowhere 

 common. Skerries near Dublin (Hyndman). "We have no 

 account of its occurrence out of Britain ; but it will probably 

 be found on the neighbouring shores of the continent. [Nor- 

 way (M' Andrew and Barrett) ; Sweden (Loven).] 



7. D. cocci'nea (Forbes), Alder and Hancock. 



B. coccinea, Forb. Eep. JEgean Invert. B. A. 1843? ; A. & H. Brit. Nud. 

 Moll. fam. 1, pi. 7. 



Bodt elliptical, bright scarlet, with a few minute black 

 spots : mantle closely covered with minute pilose tubercles : 

 dorsal tentacles short, clavate, with the laminae open in front, 

 yellowish, spotted with red ; a row of largish yellow tubercles 

 surrounds the base of each : oral tentacles linear : gills 10, 

 small, simply pinnate, erect, pointed, forming a circle. L. 0-5. 



Habitat : Under stones between tide-marks, on the coasts 

 of Cornwall and Devon ; rather rare. [Faroe (Morch) ; Brit- 

 tany (Tasle) ; Eochelle (Fischer).] ' 



This pretty species was first found on the Devonshire coast 

 by Montagu, who named it D. coccinea in manuscript, as we 

 are informed by Dr. Leach. Professor E. Forbes considered 

 it to be identical with the Doris so named by him (but not 

 described) in his vEgean Beport. Of this, however, there may 

 be some doubt. The species comes very near to D. Johnstoni, 

 but differs from it essentially in the form and number of the 

 branchial plumes. The armature of the tongue, too, is very 

 distinct in the two species.
