destructiveness, and similarly of the field mice. The two are often 

 confounded, although they belong to two separate orders, the Insect- 

 ivora and Rodentia, respectively. The general characteristics of the 

 former make them insect-eaters, while the latter are more destructive 

 to grain, roots, fruits, &c. In any individual case it is desirable to 

 know if the good or bad qualities of the group are exemplified iia the 

 particular species. 



So many of the birds are migratory and likely to be met with 

 only temporarily, that we encounter peculiar difficulties in respect to 

 making a catalogue of them. Yet, to the sportsman the migratory 

 birds are of the greatest interest, and cannot be left out. 



The reptiles form a class that is easily exterminated in a civilized 

 community, and yet there are remote hiding-places in swamps and 

 mountains where such forms may linger a long time and only rarely 

 be seen. While, to the ordinary observation, certain species would be 

 practically extinct, it would be rash to say that they are actually 

 extinct. The list must therefore be considered incomplete in this 

 respect, and information concerning snakes and other reptiles that 

 may be seen, not included in the present list, is earnestly desired. 



It is the desire of the Biologist to make a collection of the fishes 

 of New Jersey, in connection with which group of animals so much 

 . of the practical and scientific work of the biological department of 

 the Experiment Station will lie. All public- spirited persons who are 

 interested in having at the Station a representation of the various 

 fishes of their locality are invited to send specimens to the Station. 

 Such specimens can be sent packed in dry salt (in most instances), in 

 receptacles convenient for the transport of fish. In cold weather no 

 salt is needed. 



The following synopsis (which may serve as a table of contents), 

 shows the order in which the groups of Vertebrates are arranged in 

 the Catalogue which follows, and the page where the consideration of 

 each begins :
