ring weakness while young, as I never found one in this state of 

 larger size. 



Labrax Lupus, Cuv. et Val. (Basse.) Common at Barmouth, 

 North Wales, where it is caught in the mouth of the river by trail- 

 ing a piece of herring or other fish fixed on a hook after a sailing 

 boat in a brisk wind. 



Serranus Cabrilla, Cuv. et Val. (The smooth Serranus.) I have 

 seen several specimens of this fish taken by lines in a small rocky 

 bay between Rhoscolyn and Holyhead ; it is of a beautiful glossy 

 colour when taken out of the water. 



Crenilabrus rupestris, Selby. (Jago's Gold Sinny.) A single spe- 

 cimen of this rare British fish is in my possession, obtained on the 

 coast of North Wales, near Aberystwith, two years ago, having been 

 thrown upon the sand by a storm ; it agrees precisely with Mr. 

 Selby's description in the ' Magazine of Zoology and Botany,' vol. i. 

 Acerina vulgaris, Cuv. et Val. (Ruffe.) Common in the rivers 

 and canals of Shropshire ; but I have never seen any Welsh speci- 

 mens. 



Trachinus Draco, Linn. (Great Weaver.) Occasionally found on 

 the Welsh coast. 



Trachinus Vipera, Cuv. et Val. (Lesser Weaver.) Common on 

 the sandy portions of the coast, and the horror of all bare-footed 

 shrimp - catchers . 



Mullus Surmuletus, Linn. (Striped Red Mullet.) I once saw an 

 enormous shoal of this species in the harbour at Holyhead ; numbers 

 were taken in nets. 



Trigla Gurnardus, Linn. (Grey Gurnard.) Common. 

 Cottus Gobio, Linn. (Bullhead.) Common in the brooks and 

 rivers of Shropshire, but never, that I am aware, observed in North 

 Wales. 



Cottus Bubalis, Euph. (Father-lasher.) Common. 

 Gasterosteus leiurus, Cuv. et Val. (Smooth-tailed Stickle-back.) 

 The only species of this genus I have obtained in this neighbourhood, 

 and I have no doubt of it being distinct : at first, however, I sus- 

 pected this was not the case, having observed a single rudimentary 

 scale posterior to the true ones ; but although I have confined them 

 by hundreds in small pools and jars with different kinds of water, no 

 change has been produced further than increase of size. 



Pagellus centrodontus. (Sea Bream.) Common near Holyhead. 

 Scomber Scomber, Linn. (Mackerel.) Common. 

 Zeus Faber, Linn. (Dory.) I have never obtained but one spe- 

 cimen on the Welsh coast, and it is certainly not by any means com-
