Geology.] SUBANTARCTIC ISLANDS OF NEW ZEALAND. 701 



PELECYPODA. 



Pecten, Muller. 



Pecten zealandiae, Gray, Cat. Marine Moll., p. 81. 



Represented by a small fragment only, and the identification is somewhat 

 doubtfid, 



Loc. — Common in later Cainozoic of New Zealand. 



Pecten delicatula, Hutton, Cat. Marine Tert. Moll. & Echin. of N.Z., p. 30. 



Several specimens of this species were found as impressions in the flints on the 

 shore of Perseverance Harbour. The best specimens were given to me by Mr. 

 Chambers. 



Loc. — Castle Point and Chatham Islands. 



Pecten triphooki, Zittel, Voy. " Novara," Palaen., p. 52, pi. xi, fig. 4. 



My specimens were obtained near Terror Point. They differ slightly in. 

 measurement from those given by Zittel, but agree with those quoted by Hutton 

 in his Catalogue of the Marine Tertiary Mollusca. 



Loc. — East coast of Wellington and Waitotara. 



Pecten polymorphoides, Zittel, Voy. " Novara," Palaen., p. 49, pi. x, fig. 1. 

 A fragment only was found in a flint near Camp Cove. 

 Loc. — Widely distributed in New Zealand Miocene rocks. 



Lima, Brug. 

 Lima colorata, Hutton, Cat. Marine Tert. Moll, of N.Z., p. 33. 



This species was represented in the breccia at Terror Point and on the southern 

 coast. 



Loc. — Awamoa. 



Glycimeris, Da Costa. 

 Glycimeris chambersi, n. sp. 



Orbicular, thick, equilateral, with about 25 broad radiating ribs nearly equal 

 in breadth to the intervening grooves ; both crossed with concentric striae. Near 

 the margin the ribs and striae both become indistinct. Ligamental area with 13 fine 

 striae on each side, which entirely occupy all the space between the two series of 

 teeth, of which there are only 3 on each side. 



Height 2-5 in. ; length, 2-5 in. 



This species appears to resemble G. traversi, Hutton, from the Chatham Islands, 

 but differs from it in the number of ribs. The characters of the hinge of G. traversi 

 are not described. 



All my specimens were found in breccia on the south coast by Mr. Chambers. 



Venericardia, Lam. 

 Venericardia australis, Quoy. 



A single cast of this species was found in the breccia near Terror Point. It 

 occurs in many localities in the later Tertiary rocks of New Zealand.
