iaforming himself of the affinities of a particular group, but the 

 general reader would probably have welcomed a diagram or two 

 ehicidating the anatomical characters mentioned in the text : and 

 a little more detail explanatory of the method of counting scales 

 would have been useful, especially in such a critical case as that of 

 the scales between the adipose fin and lateral line of salmon and 

 trout. Mr. Regan must surely himself have been pestered by 

 people who seem unaljle to read this character for themselves. 

 Vernacular names are well chosen, and on the whole the scientific 

 nomenclature is reasonable, though a gem like BUcca hjoernha might 

 have been mitigated by the addition of a more familiar alias. It 

 might have been mentioned that " pink," given on p. 41 as a name 

 for salmon parr, applies on some rivers in Ireland to the first silvery 

 stage of sea-trout. Readers of p. 28 may possibly infer that salmon 

 are generally capable of leaping a fall of lU feet, whereas half that 

 height seems too much for most of them. 



The treatment in Chapter IV. of the different forms of trout is 

 worth close attention, especially by readers who contemplate the 

 improvement of a fishery by the introduction of supposed fixed 

 s])ecies or races. Even sea-trout are held by Mr. llegan (no doubt 

 rightly) to be reinforced in nature by the offspring of brown trout 

 and vice versa. 



The attention given to the chars is perhaps out of proportion to 

 the treatment accorded to other groups ; but while the author does 

 not expect acceptance of all his views as to the specific value of the 

 distinctions which he draws between these interesting communities 

 of colonists, isolated by profound alteration of geographical con- 

 ditions, so full a summary of his recent investigations is certainly 

 welcome. Of great convenience will be the clues afforded to the 

 maze of Cyprinoid hybridization, and the concluding chapter on 

 geographical distribution is distinctly good. On the whole the 

 worst one can say of the book is that it contains no definite promise 

 of a companion volume or volumes on the sea fishes.

Zoological Address-BooJr. 



A SECOND edition of the ' Zoologisches Adressbuch ' h;is just been 

 issued for the Gorman Zoological Society by Friedliinder and Sohn 

 for seventeen marks bound. It is a bulky volume of 1110 pages 

 and from the careful manner in which people were circularized in 

 this country should be found of great service. Universities, 

 Academies, and Societies are included, and the number of names 

 listed reaches the astonishing total of 17,800, all drawn up 

 into one index at the end. Palaeontologists are included. Errors 

 can be found; what book of this nature is free from them? and 

 such errors are frequently due to the indolence of those who receive 

 the circular and do not trouble to reply to it.
