Sutek. — Notes on Netv Zealand Mollusca. 329 



Columbella inconstans, nom. mut. 



Columbella varians, Hutton, Trans. N.Z. Inst., vol. xvii, 1885, 

 p. 314, pi. xvii, fig. 2 ; Pliocene Moll. N.Z., in Macleay Mem. 

 Vol., 1893, p. 44, pi. vi, fig. 16 (not of Sowerby, 1832). Surcula 

 varians, Suter, Trans. N.Z. Inst., vol. xxxi, 1899, p. 69 ; 

 Index Fauna? N.Z., 1904, p. 71. 



Feeling somewhat doubtful about the correctness of my 

 transferring this species to the genus Surcula, I sent some 

 fossil specimens to Mr. M. Cossmann, asking him to be good 

 enough and give me his opinion on the subject. He very kindly 

 informed me that Captain Hutton had no doubt correctly classi- 

 fied the shell. I was misled by the shallow sinus on the outer 

 lip below the suture. The specific name applied to it by Captain 

 Hutton being preoccupied, I now propose the above. 



Columbella pseutes, nom. mut. Plate XVIII, fig. 10. 



Obeliscus roseus, Hutton, Cat. Mar. Moll. N.Z., 1873, p. 22 ; 

 Journ. de Conch., vol. xxvi, 1878, p. 24 ; Man. N.Z. Moll, 

 1880, p. 72 ; Proc. Linn. Soc. N.S.W., vol. ix, 1884, p. 935. 

 Pyramidella rosea, Suter, Trans. N.Z. Inst., vol. xxxiv, 1902, 

 p. 214 ; Index Fauna? N.Z., 1904, p. 74. 



When examining the type specimens in the Colonial Museum 

 I found the columella smooth, no plications being present ; 

 the species therefore does not belong to the genus Pyramidella 

 (= Obeliscus), and its proper place is no doubt under Columbella. 

 The specific name being preoccupied in that genus, I suggest the 

 name pseutes (the deceiver). The figure is from a type specimen. 



The type specimens are from Stewart Island. Examples I 

 found in the Auckland Harbour are purplish-black with a white 

 band. 



Cominella maculosa, Martyn (1784). 



Buccinum testudineum, Chemnitz, Conch. Cat., vol. x, 1788, 

 p. 187, pi. clii, fig. 1454. Buccinum maculosum, Martyn, 

 Univ. Conch., vol. i, 1784, fig. 8. 



The name of Chemnitz having to be abandoned as being 

 polynomial, I consulted Mr. Hedley, who is always ready to as- 

 sist us New Zealand conchologists, as to the name to be adopted. 

 He very kindly sent me tracings of B. testudineum and B. macu- 

 losum, suggesting that both represented one and the same species, 

 and that in consequence Martyn's name could be used. The 

 figures, though representing shells of different size, show the 

 same main characters, and the diagnoses do not point to two 

 different species. I compared specimens from seven localities 

 in New Zealand, and I must confirm Mr. Hedlev's view as correct.
