Mr. Dendy cites the name of another of my species, and 

 criticizes it as " beyond comment." I regret that my mental 

 fciculties are so feeble that I cannot see even the slightest 

 objection to it ! 



Mr, Dendy enters a protest against the "free-and-easy 

 system of nomenclature " used by me. It is not necessary 

 to waste any words on such a phrase ; but I must enter a 

 protest against the cramped and illogical, although easier, 

 method employed by Mr. Dendy. 



I have been able to meet all Mr. Dendy 's objections in the 

 same objective and friendly manner in which no doubt they 

 were meant, however forcible Mr. Dendy's language may be. 



There is, however, one assertion which I am sorry to say 

 cannot be viewed in this light. Mr. Dendy says (p. 336) 

 that by my method I Avas " as it were capturing all stray 

 species and taking forcible possession of them." Trusting 

 that Mr. Dendy will regret the wording of that passage, I 

 feel that it is incumbent on me to express my thanks to him 

 for exposing the mistakes contained in my paper, and for 

 showing me on what points a clearer expression of my views 

 was desirable.

 between the costal nervure and the discoidal nervule are less
