268 Transactions. — Zoology. 



T. -Woods ; novce-zelandice, Sow. ; P. tabulata, Gould ; P. vari- 

 abilis, Gray : P- moesta, Ad. ; P. lirata, T. -Woods ; and P. 

 cumingii, Ad. In vol. vii., P.L.S. N.S.W., Captain Hutton 

 published a list of the fresh-water shells of New Zealand, in 

 which the species of the genus were reduced to four — Aplexa 

 antipoda, Sow. ; A. tabulata, Gould ; A. variabilis, Gray (= gib- 

 bosa, Sow. not Gould, guyonensis, T. -Woods, hochstetteri, Dkr.) ; 

 and A. moesta, Ad. In 1885 Captain Hutton gave a list of the 

 Limnceidce in these Transactions, vol. xvii., enumerating Bu- 

 linus antipodeus, Sow.; B. variabilis, Gray (= gibbosus, Hutt. 

 non Gould, novce-zealandice, Sow., guyonensis, T. -Woods) ; B. 

 tabulatus, Gould; and B. moesta, Adams (= lirata, T. -Woods), 

 giving a description and figure of the dentition of the latter. 

 The following species were omitted as not really inhabiting 

 New Zealand : Limncea wilsoni, Tryon, like Physa pyramidata, 

 Sow., from Australia ; Physa gibbosa, Gould, inhabiting New 

 South Wales; and Physa cumingi, Ad., inhabiting Queensland. 



In Fischer's Manual, p. 257. we find only two species recorded : 

 Physa guyonensis and P. moesta. With my friend Mr. Charles 

 Hedlev, of Sydney, I published in 1893 a " Eeference List of 

 the New Zealand Land and Fresh-water Shells," in which, for 

 the species of Isidora, Hutton's latest classification was chiefly 

 adopted, reducing, however, the species to three : Bulinus 

 antipodeus, Sow.; B. variabilis, Gray ( = guyonensis, T. -Woods, 

 novo3-zelandio3, Sow.) ; and B. tabulatus, Gould ( = moesta, Adams, 

 lirata, T.- Woods). Mr. Hedlev added the following species, 

 which for want of literature had escaped the notice of New 

 Zealand conchologists : B. novce-seelandice, Clessin ; tenisoni, 

 Clessin ; coromandelicus, Dkr. ; and hochstetteri, Dkr. 



The following year I published, at the request of Mr. H. 

 Crosse, a somewhat more extensive list in the Journ. de Conch., 

 vol. xli., adhering still to three species of Isidora, and reducing 

 Clessin's and Dunker's species to synonyms, as follows : Bullinus 

 variabilis, Gray ( = guyonensis, T. -Woods, novce-zelandice, Sow., 

 gibbosus, Hutt. non Gould, novce-seelandice, Clessin) ; B. tabulatus, 

 Gould (= moesta, H. Ad., lirata, T. -Woods, coromandelicus, Dkr., 

 hochstetteri, Dkr.) ; and B. antipodeus, Sow. 



I have studied now the description and copy of figure, 

 kindly supplied to me by Mr. Hedley, of Physa novceseelandice, 

 Clessin, and find it to be identical with Physa lessoni, E. A. 

 Smith, an Australian shell, and it has therefore to be omitted 

 from the list of New Zealand shells. Physa tenisoni, Clessin, 

 is according to the figure a Li m nan, being dextral. Physa 

 hochstetteri, Dunker, was mentioned by Hutton as a synonym 

 of Aplexa variabilis. Gray (anted), but was never mentioned 

 again in his later publications.
