Literature and History. 



1857.^Pfeiffer, Dr. L. " Descriptions of Fifty-eight New Species of 

 Helicea from the Collection of H. Cuming, Esq." Proc. Zool. Soc, 1856, 

 p. 324. Describes two new species of land shells from Sunday Island. Helix 

 kermandeci and H. chimmoi, collected by Lieut. Chimmo, presumably an 

 officer of H.M.S. " Herald," which surveyed the island in 1854. H. chimmoi 

 is omitted from the present list, as Iredale, who examined the type, is of 

 opinion that the locality assigned to it is erroneous. 



1873. Smith, E. A. " Description of a New Species belonging to the 

 Genus Vitrina." Ann. Mag. Nat. Hist. (4), xi, p. 288. V . kermadecensis 

 described from Sunday Island. 



1873. Mousson. " Faune Malacologique de quelques lies de l'Ocean 

 Pacifique Occidental, ii, lies de Norfolk et de Kermandec." Journ. de 

 Conch., xxi, p. 109. Kecords Microcystis kermandeci Pfeiffer, and describes 

 as new Vitrina ultima, Trochonanina exposita and Patula modicella Ferussac 

 var. vicinalis. Of these, V . ultima is the same as V . kermadecensis Smith, 

 while P. modicella var. vicinalis is omitted from the present list, as the type 

 is lost and no specimens answering to Mousson's description have since 

 been collected at Sunday Island. Mousson's specimens were collected by 

 Dr. Graeffe. 



1884. Hutton, F. W. " Revision of the Land Mollusca of New Zea- 

 land." Trans. N.Z. Inst., vol. 16, p. 186. Vitrina kermadecensis recorded 

 from the Kermadecs, and also from Hobson's Glen, AucJdand ; but the latter 

 locality is almost certainly an error. 



1884-87. ' w Reports on the Scientific Results of the Voyage of H.M.S. 

 ' Challenger.' " The " Challenger," on her famous voyage round the world, 

 passed through the Kermadec Group on the 14th and 15th July, 1874. 

 No landing was made on any of the islands, but the trawl was put over 

 three times. Two casts were made between Sunday and Macauley Islands 

 in 520 and 630 fathoms (Station 170), the bottom in both instances being 

 volcanic mud. The following species of' Mollusca were taken: Spondylus 

 ostreoides, Euplocamus pacificus, Amphitretus pelagicus, Eledone verrucosa, 

 and, on the surface, Halopsyche gaudichaudi. The trawl was again put 

 over north of Sunday Island (Station 171) in 600 fathoms, bottom volcanic 

 mud, the following Mollusca being obtained : Pecten kermadecensis, Murex 

 zelandicus, Cirroteuthis meangensis. The above species were recorded in the 

 undermentioned reports : Nudibranchiata, Dr. R. Bergh, vol. x, pt. 26, 

 1884 ; Lamellibranchiata, E. A. Smith, vol. xiii, pt. 35, 1885 ; Gastropoda, 

 R. B. Watson, vol. xv, pt. 42, 1886 ; Cephalopoda, W. E. Hoyle, vol. xvi. 

 pt. 44, 1886 (diagnoses of new species in Ann. Mag. Nat. Hist. (5), xv, 222) ; 

 Pteropoda, Dr. P. Pelseneer, vol. xix, pt. 58, 1887.

1888. Cheeseman, T. F. " On the Flora of the Kermadec Islands,

 of marine Gastropods are recorded, while mention is made of a large limpet 

 common on the rocks. 



1893. Heclley, C, and Suter, H. " Reference List of the Land and 

 Fresh-water Mollusca of New Zealand." Proc. Linn. Soc. N.S.W. (2), vii,
