Fishes of Cornwall. 3 1 1 



In one of tlie nests was an addled egg^ which was thickly 

 covered with very minute brownish green spots. Wool is the 

 staple material of the nest ; much exceeding in quantity the 

 fine dried grass with which it is interwoven and with which 

 the interior is lined: three reeds usually support the curious 

 fabric, but in the present instance, a sucker from a poplar 

 tree takes the place of one of them. 



An attempt to rear the young birds in confinement entirely 

 failed ; one of them surviving only a day, and another about 

 double that time. 1 am, Sir, yours, &c.

The sounds and seas, each creek and bay, 



With fry innumerable swarm, and shoals 



Of fish that with their fins, and shining scales, 



Glide under the green wave, in sculls that oft 



Bank the mid sea : part single, or with mate. 



Graze the sea-weed their pasture, and through groves 



Of coral stray ; or, sporting with quick glance. 



Show to the Sun their waved coats dropt with gold."

Remarks on the Species of the Genus Tri'gla. 



TRfoLA Hirundo{ Tuh-Jish). — This is oneof our commonest 

 fishes. Its usual residence is at the bottom, in sandy or stony 

 ground ; but it sometimes rises to the surface, by the aid of 

 its large pectoral fins, and strong and capacious air-bladder ; 

 an organ which in this <]jenus is firm, and furnished with 

 powerful muscles, interwoven with its tendinous structure. 

 This fish, and perhaps most of its congeners, has the faculty 

 of uttering distinct sounds, bearing a near resemblance to the 

 grunting of a young pig ; and this it will continue to do from 

 the moment it is taken to near the time of its death. 



The use of the pectoral processes is doubtful. They have 

 numerous joints along their course, and are inserted on the 

 clavicle by a joint that allows of extensive motion. A pro- 

 cess or trochanter passes off, into which is inserted a muscle 

 of great power. When either of these jointed organs is 

 directed forwards, it naturally bends into an arch. The tub- 

 fish sheds its spawn about Christmas, at no great distance 

 from land. All the fishes of this genus are distinguished bv
