" however, to know something about the ' organs ' by which it is 

 " produced. Military drums ! I should think."* 



The following is a catalogue of the species of ants which have come 

 under my notice, or have been sent to me, with short notes of such 

 manners and customs as have struck myself, or my correspondents, 

 as worth recording. Almost all the species recorded have been 

 identified, or named, by Dr, Forel, to whom I cannot sufficiently 

 express my gratitude : I must record here, as a caution, however, 

 that all these names cannot be guaranteed correct. They are 

 sufficiently so to act as pegs, on which to hang the few notes I have 

 collected ; and I trust that Dr, Forel will, in due course, publish, in 

 detail, the result of his final examination, in this Journal. I have 

 decided not to delay the publication of these notes, in the hope 

 that some member raay be sufficiently interested by them, to decide 

 to lend a hand, by collecting notes and specimens. The latter are 

 especially wanted now, at once. The greater the number of speci- 

 mens, from different localities, submitted for examination to 

 Dr. Forel, the more thorough and ^ pucka,^ will be the results he 

 will be able to give us, in the pages of our Journal, In view of 

 Dr. ForeVs promised papers, I have carefully avoided all technical 

 descriptions, save only a few, fairly obvious cbaracteristics, which 

 I have gleaned from the works of Messrs, Mayr, Emery and Roger, 

 and which, I hope, will enable members to make a rough guess 

 at the genus. I offer the plates in fear and trembling ; draughts- 

 manship has no part in my constitution, alas ! If they are any 

 way presentable, it is due to Mr, Tom Le Mesurier's artistic 

 powers ; had they been altogether his, they would certainly have 

 been better, I must also record my obligations and thanks to my 

 most patient teacher in myrmecology and very good friend. Dr. 

 Forel, and to all the gentlemen who have so kindly helped me 

 by sending me notes and specimens. May their number increase !

* Since the above was written, Dr Forel has called my attention to the fact that 

 he had long ago recorded that some European species of Camponotus make an audible 

 noise when their nest is disturbed.
