powers of discrimination of those whose species were incorporated by him into the 

 System, as he did not hesitate to adopt their views as to generic relations, however 

 much the inherent evidence of their own descriptions might oppose their views. A 

 large numher of the species were thus repeated under different specific as well as 

 generic names. The number of nominal species was thereby increased to 826, grouped 

 under 65 genera, (150a) Stcrnoptyx, (1506) Leptocephalus, (155cr) Kurtus, (165a) 

 Scarus, and (170a) Centrogttster having been added to the Linnaean genera. Gmelin, 

 however, improved on the Linnsean system by the re-combination of the Amphibia 

 nantes with the Pisces, and he re-adopted the orders (V) Branchiostegi and (VI) 

 Chondropterygii. He erred, on the other hand, in separating Mormyrus from the 

 Abdominales and referring it to the Branchiostegi.

A poor compilation, like Gmelin s, in which the various previously described 

 species were introduced without a critical study into the system, and described in 

 foot-notes in connection with the Artedian species, but combined under the Linnaean 

 genera. The nominal species (and many are only nominal), excluding the ceta 

 ceans, are thus raised from 228 to about 965, without counting the species enumerated 

 under the new genera ofauthorg appended to the volume. The compilation has some 

 value, not only on account of the original descriptions of species copied from previous 

 authors, but because of the reproductions of the descriptions of the new genera in 

 troduced by various authors into the system. It is also of interest to the student 

 of American species by reason of the incorporation therein, under specific names, of 

 anonymous American species described by Schoepf.

The title-page was modified in each volume, and the personal titles successively 

 increased in number ; the address of the publisher was changed (in v. 3-5) ; the last 

 volume (on title-page) was dedicated to his late wife ; and only the first volume 

 bears the date of the Christian era.
