THE YOUNG NATURALIST. [December 



after the London Catalogue, each followed by the names of those 

 species whose larvae have been known to feed upon it. Other in- 

 formation is briefly given, as " In the buds," " On the flowers," " In 

 confinement," &c. In most of cases an authority is given to some 

 well known work for the statements. By this double arrangement it 

 is easy to find at once all the plants on which a known larva feeds, 

 and all the larvae that are known to feed upon any plant. The work 

 of the breeder and larva hunter is thus much simplified. The work 

 is neatly and carefully printed, is of a handy size for the pocket, has a 

 useful index, and to our mind has but one fault, the time at which the 

 larvae feeds is not given, which might very easily have been done and 

 would certainly have added to the usefulness of the work. 



CATALOGUE OF THE FISHES OF THE RIVERS AND 

 COAST OF NORTHUMBERLAND AND DURHAM, 

 AND THE ADJACENT SEAS, 



BY RICHARD HOWSE. 



We are pleased to receive this new Catalogue which is a great ad- 

 vance on that published in 1769 by Wallis, which only named some 

 44 species, whilst this includes 142. This number however is made 

 up by including several species admitted by Mr. Howse to be of 

 doubtful occurrence. We are far from sure that it is wise to include, 

 in a catalogue of this kind, every species that has been recorded, but 

 Mr. Howse has been careful to call special attention to all doubtful 

 cases, and it will be found in the body of the work, that confirmation 

 is required for many of the records of the rarer species. The reader 

 must not therefore regard the Index as a list of the fishes that can 

 actually be found within the area under consideration. Thus 

 according to the index three species of Oparid2e occur, whereas two 

 out of the three are described by Mr. Howse as being very doubtful. 

 Of Cantharus lineatus he says, " the occurrence of this fish requires to 

 be verified," and of Chrysophrys auvata he says, " there can be no 

 doubt the Gilt head is very rare on this coast, even if it has ever been 

 taken." But species that appear even more doubtful than these are 

 included. On page 37 we note that Solea aumntia (The Lemon Sole) 

 is included, though apparently the only reason for including it, is the
