BRITISH NUDIBRANCHIATE MOLLUSCA. vii 



and unable to attend to them, was obliged to put them into spirits. We regret that we cannot 

 give a drawing of this interesting addition to our Fauna in a living state. From its known 

 pelagic habits, Scyllaia pelagica may perhaps be considered only an accidental visitant to our 

 shores, but it is worthy of remark that these examples were not found upon the floating Gulf 

 weed (Sargassum bacciferum), but upon one of our native algae, common in deep water. There 

 is a presumption, therefore, that the species may really be an inhabitant of our Atlantic 

 shores. 



(18) Lomanotus, (Xwfxa, border, and vwtoq, back.) 



This genus, published by M. Verany in the 'Revue Zoologique in 1844, is synonymous with 

 our Eumenis, which did not appear until the following year. M. Verany's name consequently 

 has the precedence and must be adopted. 



(19) EOLIS GLAUCA. 



Mr. Cocks has taken several examples of this fine species at Falmouth. We also got a 

 single individual while dredging near the entrance of the Menai Straits, off Beaumaris. 



(20) EoLIS CORONATA. 



t Doris longicornis, Mont., in Linn. Trans., v. 9, p. 107, pi. 7, fig. 1. 

 Eolida plwnosa, Flem., Brit. Anim., p. 285. 



An inspection of the original sketch of Dr. Fleming's E. plwnosa induces us to think 

 that it is the young of E. coronata. The characters of the head and tentacles* exactly 

 correspond with this species, and the paucity of branchial papillae may be accounted for by 

 supposing the specimen to have been injured, as these organs very readily fall off. 



With regard to the Boris longicornis of Montagu, we cannot speak with confidence, but 

 an examination of the southern coasts of Devonshire and Cornwall has brought to light no 

 species excepting Eolis coronata that could with any probability be referred to it. In Fowey 

 Harbour we got some large specimens of a curious variety of the latter. The branchiae were 

 of a less vivid red than usual, and they, as well as the back, were much spotted with pale 

 blue or bluish- white ; in this particular agreeing with Montagu's description of longicornis, in 

 which the "cirri" are stated to be of a pink colour spotted with white. His figure is so bad 

 that little reliance can be placed upon it. It appears, from its general contour, to represent 

 an Eolis of the section with clustered branchiae in which some of the anterior clusters had 

 fallen off, and one of them was in progress of being reproduced. The colour of these organs 

 shows a mixture of blue with the pink, in which also it agrees with E. coronata. We do not, 

 therefore, feel sufficient confidence in its distinctness to give the species a place in our 

 Synopsis, but shall insert Montagu's description here as a guide for further investigation. 



" Doris longicornis. Body long, slender, posterior end acuminated ; head rounded in front : 



* Dr. Fleming informs us that the word " dextral" in the description of the tentacles is a 

 mistake of the printer, and ought to be " distal."
