Such, then, is Dr. von Lendenfeld's arrangement of the 

 group ; I leave it to speak for itself, and will proceed at once 

 to discuss the nomenclature adopted by him for the genera 

 and species. 



III. The Nomenclature of Genera and Species. 



On this subject a great deal might be said ; but I will 

 endeavour to make my remarks as short as possible. 



That Dr. von Lendenfeld holds very peculiar views on the 

 subject of zoological nomenclature will be evident from what 

 follows. 



Firstly with regard to his new genera, I would venture to 

 point out that the very remarkable genus 8pirophora appears 

 to be thoroughly identical with Mr. Carter's Trachycladus^ of 

 which the type species (possibly identical with one of those 

 described by Dr. von Lendenfeld) was fully described so far 



* Dr. V. Lendenfeld remarks, " Diese Gattimg soil eingezogen werden, 

 wie Mr. Dendy mittheilt." This is quite true ; but he does not say what 

 is to become of the three species included in it, viz. D. fibrosa, D.fragilis, 

 and D. melioi: In our ' Challenger ' Report we have included these three 

 species in the genus Pachychalina.
