404 Mr. W. Thompson on the British Species of 



tent be done, the sequel will show that it cannot be per- 

 formed effectively. 



First : — the Variegated Sole as figured and described by- 

 Donovan and Yarrell, the specimen recorded by Dr. Scouler*, 

 and the individual noticed by myself under the name of Solea 

 variegata, are identical. The localities in which this species 

 has been procured, are the coasts of Cornwall in England? 

 of the island of Bute in Scotland, and of Down in Ireland. 

 As suggested in my previous paper on this subject, it may 

 be worthy of investigation, whether the Mon. Pegusa of 

 Risso, obtained from the Mediterranean, be this species, (t» 

 iii. p. 258. f. 33. ed. 1826) f . Of the references in Mr. Yarrell's 

 work, those relating to Rondeletius, Willughby and Cuvier 

 apply, I conceive, to the species next to be noticed ; Duhamel 

 I have not for consultation ; Fleming merely quotes Donovan 

 and Pennant. 



Spec. char. Mon. variegatus. Pectoral fin about £ the 

 length of head : scales on lateral line about 85 ; dorsal and 

 anal unconnected with caudal fin. 



Secondly : — the SoleaLingula of Jenyns's c Manual,' (except- 

 ing the short specific characters and colours which are copied 

 from Hanmer,) the Mon. minutus of Parnell, and the " Solea 

 Lingula, Rond.," (Mon. linguatulus) described by me in the 

 6 Annals/ are the same species; — of the identity of these two 

 last I judge from a comparison of specimens. Being of opi- 

 nion that Mr. Jenyns's description, so far as taken from the 

 individual before him, related to this species ; and that, 

 rather than describe the colours from a specimen preserved 

 in spirits, he had copied them from Hanmer's description 

 of the Red-backed Flounder, believing it the same, though 

 it is in reality a distinct species ; I communicated with him 

 on the subject, and his reply confirmed my views. The op- 

 portunity of examining specimens of this latter fish, which 

 Mr. Jenyns had not, but through the kindness of Dr. Parnell 



* As this fish is very briefly noticed in the Magazine, I wrote to Dr. 

 Scouler respecting it, and was informed in reply that it may be considered 

 identical with the Variegated Sole of Yarrell. 



f The large size of the pectoral fin, as represented in the figure, marks a 

 Solea rather than a Monochirus ; but it is described as the latter by Risso, 

 and the figure referred to as such by Cuvier, Reg. An., t. ii. p. 343, 2nd ed.
