354 PROCEEDINGS OF THE MAT.ACOLOGICAL SOCIETY. 



A specimen collecterl by Mr. A. Hamilton, now Director of the 

 Colonial Museum, "Wellington, and very kindly presented to me, 

 perfectly agrees with Reeve's description and figure, with the 

 exception of the situation of the apex, which is at the anterior fourth 

 of the length, hut this is subject to great variability with most of our 

 limpets. My specimen is subpellucid, the radiate close ribs number 

 about 40, and are crossed by close distinct concentric striae. It is 

 a little smaller than the type; the dimensions are: length 33, breadth 

 24, height 9 mm. 



It is quite distinct from N. illuminata, and forms a very interesting 

 addition to the fauna of the Southern Islands of New Zealand.

 Sah. — Kermadec Islands. 



In Trans. N. Zeal. Inst., vol. xx (1888), p. 165, we find the 

 following passage with regard to the mollusca of the Kermadecs : — 

 '* A large limpet, more than 5 inch, in diam., is common on the rocks." 



DouMful New Zealand Species. 

 Patella floccata, Keeve. 



Conch. Icon., vol. viii, fig. 106 (1855). Collected in New Zealand 

 by Mr. Earl. 



We first find this species mentioned again by Hutton as Nacella 

 floccata, Peeve, Hutton, Cat. Mar. Moll. N. Zeal., p. 45 (1873). 

 Martens, in his Crit. List. Moll. N. Zeal., does not mention it at all. 

 Hutton remarks : " This appears to me to be a variety of N. argentea?'' 

 Again, in his Revision des Coquilles de la Nouv. Zelande (1878), 

 Capt. Hutton enumerates Patella floccata with the note : " Je n'ai vu 

 aucun specimen de cette espece." Further, in Hutton's Man. N. Zeal. 

 Moll. (1880), we find this species as a synonym of P. pholidota, Lesson, 

 and this is repeated in his revision of the Docoglossate Mollusca, 

 P.L.S. N.S. Wales, 1884. Pilsbry accepts Hutton's synonymy in the 

 Man. Conch. (1), vol. viii, p. 140, and reproduces Reeve's figures of 

 Patella floccata, pi. Ixix, figs. 38, 39.
