Art. XVII. — On a new Species of Giant Cuttlefish, stranded at 

 Cape Campbell, June 30th, 1886 (Arcliiteuthis kirkii). 



By C. W. EoBSON. Communicated by Dr. Hector. 

 [Read before the Wellington Philosophical Society, l^th July, 1886.] 



Cape Campbell and the adjacent coasts seem to be places of 

 favourite resort for these great Cephalopods during the winter 

 mouths, a year seldom passing without one or more of them 

 being cast on shore, usually during the months of June and 

 July. The greater number, however, of these, owing to the 

 attacks of sharks, dogfish, and poi-poises, are stranded in such a 

 mutilated condition as to be of little value to the naturalist; but 

 I am quite satisfied, from the examination of a number of 

 imperfect and of two perfect specimens, that they are all 

 Decapods. None of the Octopods which have come under my 

 notice have a solid heavy body like the Decapods, and they all 

 seem when cast on shore to be able to return to the water
