1. Lepas anatijera Linnaeus. 



General type: Canterbury Museum; locality unknown. *Otago 



Museum, " Ship's bottom, 1905.'" 



As noted in the list above, this species has been collected at the Ker- 

 madecs and at Chatham Islands, but it is not certainly known to occur in 

 New Zealand proper. 



2. Lepas hillii Leach. 



" Terra Nova '" hull. Lyttelton, 1910. 



3. Conchoderma aurita Linnaeus. 



"• Terra Nova " hull, Lyttelton. 1910. *Otago Museum and Auckland 

 Museum, attached to whale. 



4. Conchoderma virgata Spengler. 



" Terra Nova " hull. Lyttelton. L910. *Ship's hull, Dunedin. 



5. Lithotrya dorsalis Sowerby. 



Canterbury Museum : locality unknown. 



6. Ibla quadrivalvis Cuvier. 



Canterbury Museum : locality unknown. 



I have included specimens obtained from the " Terra Nova in my 

 reliable list only when the species from other information is definitely known 

 to occur in the New Zealand region. The " Terra Nova " was Captain 

 Scott's Antarctic exploring vessel, with a wooden hull. Her route from 

 England to New Zealand was via Cape Town, Hobart, and Melbourne, and 

 the specimens were gathered shortly after her arrival in Lyttelton in 

 October, 1910. 



In addition to the above well-preserved material, there are dry specimens, 

 mounted on cardboard, in my collection and in the museums throughout 

 New Zealand. They are not of much value in this connection, and do 

 not add to the list. Hutton's type specimen for his new species Pollicipes 

 darwini is unfortunately in this condition. It was briefly described on 

 external characters only, and never figured. 



It is hoped that this list will form a reliable foundation for addi- 

 tions to the group, which are certainly to be found in this region. 

 So far it has been very imperfectly explored, and the material already 

 collected has often been wrongly named, owing to the difficulty of the 

 classification. 



Note.— Hutton"s list of New Zealand pedunculate Cirripedia (1879) is 

 as follows : Lepas hillii, Lepas pectinata, Lepas australis, Lepas fasdcularis, 

 Scalpel] inn villosum, Pollicipes spinosus, Pollicipes darwini. 



The identity of the specimens identified by Hutton as L. hillii is not 

 certain now. They are dry, rather small, with no umbonal teeth, and a 

 carina not strongly forked. As will be seen in the following section, this is 

 not sufficient to distinguish them from certain forms of L. anatijera and 

 L. australis. The filaments would decide the matter, but these cannot 

 be made out from the shrivelled animals. There is no certain evidence 

 of L. hillii yet having been collected from the New Zealand region.
