78 THE VICTORIAN NATURALIST. 



This neat though small everlasting is dedicated to Charles 

 Troedel, Esq., an honoured friend of the author through many 

 years, from whose splendid lithographic establishment many 

 hundred plates have emanated for works issued by the Phytologic 

 Department of Melbourne. According to strict right of priority 

 the generic name Argyranthus takes precedence over that of 

 Helipterum. 



Helipterum rubellum was found near Mount Caroline by Miss 

 Julia Wells. 



H. incanum and H. moschatum extend to the Warrego ; L. 

 Henry. 



H. polyphyllum ; southward to the Tweed, Rev. B. Scortechini, 

 and to Narrabri, Betche. 



H. corymbiflorum ; Bowen-Downs, Ch. Birch. Small specimens 

 with single headlets of flowers sent from the Flinders-River by 

 Mr. Th. Gulliver. Rays rarely rosy-red. Illustrated in Wawra 

 and Beck's " Itinera Princ. Coburg." ii., 35, also H. dimorpho- 

 lepis, ii., 36. 



H. pterochcetum ; Mulligan-River; W. H.Cornish. 



H. polycephalum ; near the Stirling's Range, F. v. M. Occa- 

 sionally some few of the outer flowers devoid of a pappus. 



B. Iceve; Pulpulla, Josephson ; base of Stirling's Range, F. v. 

 M. Corollas very slender. 



H. exiguum; near Swansea, Tasmania; A. Simson. 



H. dimorpholepis ; Severn; Rev. B. Scortechini.

MIMICRY IN THE ANIMAL WORLD. 



By Rev. George D. Hutton, M.A., B.Sc. 



(Read before the Field Naturalists' Club of Victoria, St/i September, 



1S90.) 

 In bringing this subject under your notice this evening two reasons 

 influenced me. The first is that, unlike most of you here, I have 

 been unable to find time for any field work. I had thus to take up 

 a general subject. The second reason which induced me to take 

 the special subject of mimicry was that, in the course of reading 

 on the results of the travels of naturalists, no examples of mimicry 

 were noted from Australasia. This, I believe, is not due to the 

 fact that none exist, but because no attention has been paid to it. 

 I feel, then, that though this paper contains very few original 

 observations, it may lead to such by suggesting regions of observa- 

 tion to some who have the opportunity of traversing them. 



The term mimicry is now pretty much narrowed down to cases 

 in which one species so closely resembles another species, in its 

 form, in its coloration, and in its habit, as to be often mistaken
