of Central Europe agree with those from the lochs of Scotland and 

 Ireland, or how the characters which we think entitle them to sepa- 

 ration are kept up in other localities. We shall look anxiously for the 

 appearance of the Second Livraison and the letter-press, when we shall 

 endeavour to enter more folly upon this curious subject ; in the mean 

 time we would wish that encouragement to the work in this coun- 

 try which is due to the persevering zeal of its author. 



The History of the British Salmonidce, by Sir W. Jardine, which stands 

 next upon our list, is a work which has also been some time in prepa- 

 ration, and of which the first Fasciculus of six plates is now published.* 

 The figures are here drawn as near the size of life, as that of the paper 

 will admit of, and are engraved with the view of giving the effect of 

 the newly taken fish ; all the details of anatomy, scaling, and outward 

 structure, which require most minute execution, being reserved for 

 the volume which will contain the descriptive letter-press, and which 

 will appear with the last fasciculus of the plates. The sketches for 

 the colouring we know to have been nearly all made at the water's 

 edge from the fish when newly caught ; thus endeavouring to preserve 

 an imitation of the rich tints which so quickly fade, and are lost in 

 preserved specimens ; and the department itself has been entrusted 

 to, and performed with much credit by Mr. Bayfield of London. It is 

 expected that the whole species found in the waters of Britain and 

 Ireland will be illustrated in six fasciculi, or upon from thirty-six to 

 forty plates. 



On the two first plates before us are figured the Gilse or state of 

 S. salar before having spawned, the second being named with a? and 

 considered to represent the same state of the second species of British 

 Salmon, whose history has scarcely yet been noticed by our ichthyolo- 

 gists. Plate 3. represents S. albus of Fleming, given under that name 

 to identify without doubt the fish alluded to in the " British Animals," 

 and so often referred to by our modern writers. This is now known 

 to be the young of our migratory species confused together, and in 

 this state extremely difficult to separate. 4. is a variety of the large 

 S. ferox, which we noticed M. Agassiz does not include in his fist of 

 the fishes of Central Europe ; the specimen is remarkable for the close 

 and numerous spottings over the whole body. 5. are two beautiful lacus- 

 trine varieties of S. fario, and 6. exhibits figures of the Lochmaben 

 Coreyonus C. Willuyhbeii, Jard. The second fasciculus, which is in 

 preparation, will contain, 1. S. salar, adult male in the dress of the 

 spawning season ; 2. S. salar in a very young state ; 3. S. trutta, adult
