428 Prof. C. Chilton on the Distribution of 



This beautiful Phascogale diff(M-s so conspicuously from 

 the Ph. cristicauda, Kufft, as identified by Baldwin Spencer 

 after comparison with the type, that I have no alternative 

 but to describe it as distinct, though I have little doubt that 

 its skull will show it to be closely allied to that animal. I 

 liave much pleasure in naming it after its donor, to whom 

 the National Museum owes a number of interesting specimens 

 from t\iG same locality. 



XLVIII. — Azotes on the Distribution of some Species of 

 Terrestrial Isopoda introduced into Australasia. By 

 Charles Chilton, M.A., D.Sc, F.L.S., Professor of 

 Biology, Canterbury College, New Zealand. 



In this short paper I give a few notes on the distribution, so 

 far as it is at present known, of some species of terrestrial 

 Isopoda that appear to have been introduced into Australasia, 

 most probably by the unconscious action of man. I have 

 already pointed out elsewhere * that the terrestrial Isopoda 

 are well worthy of study from the point of view of the 

 geographical distribution of animals, and it is therefore 

 (IcsirabJe to place on record any facts illustrating the spread 

 of different species at the present time. Two or three of the 

 species introduced into Australasia have been described a.s 

 new local species, and until these are reduced to the rank 

 of synonyms lists of the species inhabiting any part of 

 Australasia are apt to be misleading. 



Only references necessary for workers in Australasia have 

 been given ; full references and synonyms can be found in 

 the works by Dr. Budde-Lund and Professor G. O. Sars. 



My collections from Australia are as yet rather 



meaarre 



but Messrs. Helms and Sayce have sent me specimens from 

 various localities in New South Wales and Vietoria, and 

 Messrs. W. and E. M. Laing from Norfolk Island. To 

 these gentlemen my thanks are due, and also to Monsieur V. 

 Bouge, who has taken considerable trouble to send rae 

 specimens from New Caledonia.
