] HOWE, The Genus Climactcris. 41 



A subsequent examination of the skin of Cliiuacteris zvaitei 

 leads me to believe that it is an immature male of C. picumna. 

 I hope to deal more fully with this later on. 



The study of this interesting genus has been a pleasurable 

 task, and if such small groups of birds (a genus) or even an 

 individual are similarly dealt with, the result and information 

 obtained would certainly help to eliminate the straw-splitting to 

 which Australian ornithology has recently been subjected. As 

 already remarked, the most perplexing form is Climactcris 

 Icucopha-a uiiuor, a miniature of the southern AVliite-throated 

 Tree-creejier {C. IcucophcBa). Mr. A. J. Campbell^ remarks 

 "that the difference appears more specific than sub-specific," 

 and states the differences and measurements of both. 



After an exhaustive examination of the available material, I 

 append a list of the species and sub-species I would admit.
