240 THE ZOOLOGIST. 



fairly eclectic spirit, cannot fail to be advantageous to the method 

 of a cabinet arrangement, even if leading to no higher biological 

 conception. 



In the sketch of the literature of Lepidoptera we are some- 

 what appalled by being reminded that " eighteen languages at 

 least are employed in entomological works at the present day." 

 Class A, of which a knowledge is considered necessary, includes 

 English, French, Latin, and German. Class B, important but 

 less necessary, comprises Dutch, Swedish, and Russian. Cliss C, 

 valuable, but still less necessary, contains Italian, Spanish, Por- 

 tuguese, Danish, and its near ally Norwegian. Class D, some- 

 times wanted, as Polish, Czech, and Magyar. Class E, probably 

 unimportant, in which is enumerated Croatian, modern Greek, and 

 Japanese. We are consoled by the reflection that though we know 

 many entomologists, we are unacquainted with any possessing 

 such polyglot accomplishments. 



The faunistic bibliography given by Mr. Kirby is an excellent 

 compilation, containing all that must be consulted for a primary 

 knowledge of the Lepidoptera of the various regions detailed. 

 There is also to be found a good list of the principal " books on 

 Lepidoptera in general."
