'Entirely black, spines large, flat, black, grey, or black or grey with wliile tips ;

I think that, from the evidence at jjresent available, we are justified, in opposi- 

 tion to Mr. Allan, in concluding that there are five forms oi Zaijlossus bruijiii, each 

 confined to a more or less definite geographical area : but that in the lower north- 

 western portions of the Arfak Peninsula and the foot-hills west of the Fly River 

 the species is still in an unfi.xed state and that specimens are found there resembling 

 one or the other of the five sulispecies as well as all sorts of intergradations. I 

 cannot, however, see why this should invalidate the five forms, which as far as 

 wu know occnr locally over considerable separated areas. 



In the same way I consider that, although in some small areas in Australia we 

 find a mixed race of Tacli>/(/lox!<HS, there are at least three good localised subspecies 

 of Taclii/glossus aculcata in addition to T. a. latvesi of New Guinea and T. a. setosa 

 of Tasmania. When careful comparisons have been made, I even believe that we 

 shall find that the specimens from South-west and North-west Australia and Cape 

 York are also distinct. 



I append a key of the five described races. 



I Pelage thick, woolly, and pale cinnamon-brown, spines short, almost hidden, third 



1 claw stout and long : 7\ aculeata setosa Tasmania. 



'.Pelage sparser, more hair-like, dark brown or yellowish, third claw small : 2.

2 T. aculeata aculeata New South Wales and South Queensland. 

 IPelage thinner or almost absent except on belly : 3. 



rSize small, spines long and dense, white marked with brown or giey, hair 

 3- brown: T. ae«feato /a«!e«? S.E. New Guinea. 



Isize large : 4. 



Pelage almost absent except on belly, brown, spines long, thick and dense, 

 white with brown markings or black with white tips : '/'. aculeata aaanthion, 

 Northern Territory of South Australia. 



Pelage well developed, long, yellowish, spines long, thin and very dense, 

 white : 7". aculeata multiaculeata Southernmost South Australia.
