Beaumont — Fauna and Flora of Valencia Harbour, Ireland, 815 



XI. — Rbpoet on the Nemertea. By W. I. Beaumont. B.A. 



Intkodxjction. 



On both our visits to Valencia, Nemertines were obtained in consider- 

 able numbers in tbe harbour. In all, twenty-three species are here 

 recorded. All of these are to be found in Valencia Harbour itself, 

 with the exception of Carinella inexpectata. This species, of which a 

 single specimen was dredged in 45 fms. to the south-west of Valencia 

 Island, is an addition to the Atlantic fauna. Nemertopsis tenuis is also 

 an addition. to the British list; but it has been described by Joubin 

 (1894) from the coast of Brittany as a variety of the species well 

 known to British naturalists as Tetrastemma flavidum (here transferred 

 to the genus Nemertopsis, and probably not identical with Tetrastemma 

 flavidum, Burger), and I am not quite convinced of its specific rank. 

 The species referred with some doubt to Tetrastemma cephalophorum, 

 Biirger, was known to occur at Plymouth and Port Erin, but had been 

 recorded as FrosorJiochmus Claparedi (Riches, 1893; Beaumont, 1895). 



There has recently appeared a list of Irish Nemertines (Proc. 

 Boyal Irish Acad. (ser. 3), vol. v., 1898) compiled by E. B. Jameson 

 from existing records, including those named on my authority in 

 Gamble's account of our first visit to Valencia (Irish Nat., 1896). 



The classification of Burger has been followed. 



Order.— PROTONEMERTINI. 

 Family.— CARINELLID^. 



Genus. — Caeinella. 

 Carinella annulata (Montagu). 



Carinella annulaf a, Burger (1895), p. 523; {pro parte) M'Intosh, 



Hubrecht, &c. 

 Carinella Araffoi,Joubva (1894:) ; Beaumont (1895); Gamble (1896). 

 Carinella M'lntoshi, Biirger (in earlier publications) ; Eiches ( 1 894) . 



There can be little doubt that this species is the type of 

 Montagu's Gordius anmdatus, and not the one following under 

 the name Carinella superha. The latter appears to have been 

 recognised by Montagu, as also by M'Intosh, but regarded
