42 A CORNISH FAUNA. 



rayed visitor from the tropics of some other species, just as 

 were Kay's bream and Pimelepterus Cornubiensis. 



Rock cook. (Acantholabrus exoletus). Small mouthed wrasse. 

 Common and well defined, but I am by no means certain that 

 it is not L. maculatus or L. coquus in its young form. 



Corkwing. (Crenilabrus Cornubicus). Gold finny. Yery com- 

 mon, but as Couch says, " the Corkwing like others of its 

 family varies in its colours. 



Jago's Goldsinny. {Crenilabrus rupestris), Cuvier). Common, 

 but it is frequently a matter of great difficulty to say when 

 a specimen is corkwing and when goldsinny. 



Rainbow Wrasse {Julis vulgaris) has occurred once only. In 

 Mount's Bay. 



Two-spotted Wrasse (see "Fauna") is probably another name 

 for the three-spotted wrasse. See Yarrell, Yol. I, p. 286, 

 ed. 1836, where he gives the synonym of " Doubly-spotted 

 wrasse" to L. trimaculatus. Hog wrasse is abandoned by 

 Couch in British Fishes. 

 I think I have said enough to show that the classification of 



the Labridee is in a most unsatisfactory condition, and requires 



the close attention of ichthyologists. 



CYPRINIVJE.—^k Carps). 



The Carp. ( Cyprinus carpio). A pond fish throughout Cornwall. 

 The Gudgeon ( Gobio fluviatilis) said by Couch (British Fishes) to 



have been introduced of late into Cornwall, and to be thriving 



" in some ponds near Penzance," but I do not know of it. 

 The Tench. {Tinea vulgaris). A common pond fish. 

 Gold-fish. {Cyprinus auratus). A pond fish, of course not 



aboriginal. But it breeds in ponds. 

 Dace. (Leuciscus vulgaris). Common in the Tamar and its 



tributaries. 



Minnow. (Leuciseus phoxinus). Minnis. Of ten confounded with 

 the three-spined stickleback. Common. 



Loach. (Cobitis barbatula). Occurs in Cornwall, but I think it 

 rare. From my experience of it in other counties, I can 

 fully agree with those who say it is " delicious food" 

 (Couch British Fishes, vol. 4, p. 70), if only you can get 

 enough of them to make a dish.
