ISOPODA.

N.Z., p. 263. 



One small specimen, dredged off Great Barrier Island, ap- 

 pears to belong to this common species, but it is immature, 

 and the eyes very indistinct, so that the identification is not 

 free from doubt. 



Among the Isopoda were two or perhaps three species of 

 Sphceromidce, one apparently belonging to the genus Ciliccea, 

 and new to New Zealand. But I cannot identify these with 

 existing species, and do not care to venture on the description 

 of new species of this difficult family pending the appearance 

 of Dr. H. J. Hansen's work on the genera of the group. 



Art. XXXI. — List of Crustacea from the Chatham Islands.

Canterbury College, New Zealand. 

 [Read before the Philosophical Institute of Canterbury, 6th December, 1905.] 



In connection with the origin of the fauna of New Zealand 

 that of the outlying islands is of especial importance, and I am 

 therefore giving here a list of some Crustacea from Chatham 

 Islands, a group situated about 450 miles east from Lyttelton 

 Harbour. It will be seen that the list is a very short one, and 

 this must necessarily be the case, for no systematic collection 

 of the Crustacea has been so far made, and I have only a few 

 specimens that have been gathered at odd times by Mr. A. 

 Shand, Miss S. D. Shand, Professor Kirk, and Dr. Dendy. The 

 list, indeed, would be hardly worth while publishing of itself, 

 but I hope that it will be the means of causing others who may 

 have the opportunity of doing so to pay special attention to 

 the fauna and flora of these and other outlying islands of New 

 Zealand. The terrestrial and fresh-water faunas are of the great- 

 est value in this connection, and it is of extreme importance 

 that they should be studied, and if possible preserved, before 

 it is too late.
