82 IJECUl.'HS OF TIIK AUS1I;.\I,1AX Ml'SKlM. 



Ohs. — One specimen of what appears to be the above, and whi(;b 

 agrees veiy well with L. Koch's description and figure, is included among 

 the " Chevert " material, but it is, as suggested b}- Hogg (s/ijirn), in all 

 probability a young example of some other genus. The specimen under 

 discussion has its tarsal scopnla? diA'^ided by a tine line of seta?, but 

 Ml". R. J. Pocock has pointed out*^ that among those species which in the 

 adult state have an integral scopula, the latter is always more or less 

 (liA'ided in the earlier stages. As there is only one example in this 

 collection, and that one damaged, I prefer to follow the example of my 

 friend, Mr. H. R. Hogg, and to let the matter remain as it stands fui' the 

 present. Koch's ty})e came from Port Mackay, North Queensland.
