Rules for Zoological Nomenclature. 173 



fication which it has received from the hands of its original 

 author. The course, as Mr. Shuckard observes, is clear 

 enough, although it does not appear to be exactly that which 

 he has followed. I should say, without hesitation, that the 

 generic, or rather, perhaps, subgeneric, names of these groups 

 ought certainly to be applied in the following manner : — 



Genus Pemphre v don Latreille. 



Subgenus 1. Pemphredon proper (Diodontus Curt.), real type P. mi- 

 nutus F. 



2. Passalae^cus Shk. (Xylae v cus Shk. in lab.), type Diod. in- 



signis C. 



3. Ceratophorus Shk. (Pemphredon p. Curt.), type P. mdrio V.L. 



4. Cemdnus Jur. (Pemphredon Lat., Curt., Shk.), real type 



lugubris F. 



5. Dineurus* Westw. (Cemonus Shk.), type P. unicolor Lat. 



I will first add, by way of reply to those who would retain 

 a generic name for species not agreeing with the type species, 

 which last may have subsequently been proved to belong to 

 an already named genus, that it must be evident that the 

 author, in constructing such genus, must especially have had 

 in view the typical species, which, indeed, often furnishes the 

 generic name ; that, by removing such type, the creation is 

 dissolved, the tie which held the remaining discordant ma- 

 terials together is broken ; and that, after the removal of 

 that type, it would be as improper as practically injurious, to 

 speak of the remainder as constituting such or such a genus 

 of the author by whom the name was proposed. 



Art. II. Rides for Zoological Nomenclature. By Hugh E. 

 Strickland, Esq., F.G.S. 



In order to exhibit more clearly my views on this subject, 

 I have drawn up a few general rules, divested as much as 

 possible of unnecessary verbiage ; and beg to submit them 

 to the consideration of your readers. They have little pre- 

 tension to originality, but are selected from the writings of 

 several naturalists, especially from the Birds of Mr. Swainson, 

 many of whose aphorisms are adopted here. 



1. The Latin nomenclature forms the only legitimate 

 language of zoology (Sivainso?i). 



Latin names are adopted by naturalists of all nations, and are therefore 

 preferable to any other. Where one language is sufficient for the purpose, 

 all others are superfluous. 



2. Names which have been long adopted and established 



* From the first submarginal cell receiving two recurrent nerves.
