[Rend before the Canterbury Philosophical Institute, 2nd December, 1914.] 



The objects of this paper are— (1) to give a reliable list of stalked barnacles 

 collected from the New Zealand region ; (2) to discuss the characters which 

 are at present regarded as specific in the cases of Lepas anatifera and 

 Pollicipes darwin i . 



The specimens the work is based on belong to the only two important 

 existing collections in Xew Zealand that I am aware of- viz.. that of the 

 Otago Museum, which includes Captain F. W. Hutton's original collection, 

 and mv own collection at the Biological Laboratory, Canterbury College, 

 which includes a large amount of material collected and in some cases 

 already described by Dr. Charles Chilton. 



The works of reference I have made most use of are — (1) Darwin, 

 C. (1851), "Monograph on the Cirripedia: Lepadidae" ; (2) Hutton, 

 F. W. (1879), "List of Xew Zealand Cirripedia," Trans. N.Z. Inst., 

 vol. 11. p. 329; (3) Gravel, A. (1905), " Cirrhipedes " ; (4) Pilsbrv. (1907),

 bury Museum, vol. 1, No. 3, p. 311; (6) Chilton, C. (1911), "Dispersal 

 of Marine Crustacea by Means of Ships,'" Trans. N.Z. Inst., vol. 43. p. 132 ;

 lection at the Biological Laboratory. Canterbury College, Christchurch.] 



The following is a complete list of pedunculate Cirripedia gathered 

 from the region of New Zealand and the surrounding islands (Auckland, 

 Campbell, Chatham, and Kermadec Groups) up till December. 1914.

 mentioned.
