MELVII.L: NOTES ON THE GENUS HARPA. 37 



II. — Harpa punctata Verco. 



Harpa punctafa Verco, Trans. Roy. Soc. S. Australia, 1896, p. 218, 

 pi. vi., f. 3, 3a, 3b. 



Habitat : Two recent and two broken, at 20 fathoms, Newland Head. 

 One dead and one broken, 22 fathoms, Backstair Passage, Australia. 



The only recent species added of late years, and distinguished by 

 its distant ribs and dotted ornamentation, rendering it most distinct. 

 In form it resembles the tertiary H. mutica, and Dr. Verco has lately 

 placed it in the sub-genus Eocithara, to which most of the fossil 

 forms appertain. 



H. ventiicosa and H. minor Lamk. are noted as Australian species 

 likewise, ranging from the north to north-west of that continent. 



Note. — Harpa costata (L.) var. latifica : It has been pointed out 

 to me by Mr. J. M. Williams, of Liverpool, who was kind enough to 

 forward a very fine beautifully coloured specimen of the above variety, 

 that no mention was made of the thin, very acute, undeveloped riblets 

 longitudinally running between the cost^e, in the exact centre of each 

 interstice. 



Catalogues and JCIonographs of the Genus. 



Harpa has been monographed, so far as its recent species are con- 

 cerned, by Martini and Chemnitz, Lovell Reeve, L. C. Kierier, G. B. 

 Sowerby, August Sutor, and George W. Tryon, jun. It will, perhaps, 

 be of interest to give the species named by each, which demonstrates 

 the doubt that has existed amongst experts since the time of Linnaeus, 

 as to their limitation. I also give Lists from Agnes Catlow's Concho- 

 logists' Nomenclator ; F. Paetel, Catalog der Conchylien Saramlung; 

 and J. G. Hidalgo, Cat. Moll. Test, de las Ins. Filipinas (1904-5).
