Bolten., 1798, p. 125, is the Mediterranean shell, and is also earlier than 

 Perry's name. I cannot differentiate Australian, Kerraadec, and Neozelanic 

 specimens from Mediterranean examples, though I have been prejudiced 

 in favour of that course by Hedley's decision (Biol. Res. " Endeavour," 

 vol. ii, 1914, p. 65). In coloration, degree of nodosity, and size, austral 

 specimens easily match northern shells, and I conclude variation is due to 

 station of life, not locality. At the Kermadecs I found many examples 

 living below low-tide mark which were all decollate, much eroded, and 

 comparatively small ; but specimens washed up from deeper water — pro- 

 bably 10 to 15 fathoms — were of much larger size, and quite clean. No 

 difference whatever can be seen by me at present between these and northern 

 shells. This would agree with Hedley's experience (loc. cit.), as I would 

 regard his var. euclia (pp. 65-66) as a deep-water representative of the 

 austral shell. The wrinkling on the columella and inner lip is a character 

 which differs with age, younger specimens showing heavy wrinkling such 

 as is seen in tritonis Linne, but this becomes obscured by a heavy callus 

 with age. For Neozelanic and Australian shells I must therefore recommend 

 the usage of Charonia lam/pas (Linne, 1758), and this conclusion necessitates 

 the acceptance of T. sauliae Reeve as a synonym. 



Cymatium parthenopeum (von Salis, 1793). [P. 305.] 



Such is the name to be used for Septa costata (Born, 1778) given by 

 Suter. Murex costatus Born, 1778, is preoccupied by Murex costatus Pennant, 

 Brit. Zool., ed. 4, vol. iv, p. 108, 1777. The next recorded synonym is 

 Murex parthenopeus von Salis, Reise Neapel., p. 370, 1793. According to 

 Watson (Chall. Rep. Zool. vol. xv, p. 391, 1886), the reversion to this 

 specific name should be welcomed. Suter has placed the species in the 

 genus Septa under the subgenus Lampusia Schumacher, 1817. This is 

 obviously an error. It must be classed in the genus Cymatium Bolten, 1798, 

 and the subgeneric name is Monoplex Perry, " Conchology," pi. hi, 1811, 

 this species being figured as fig. 3 under the name Monoplex australasiae, 

 which was long ago selected as type of Monoplex. The name Monoplex 

 anstralasiae should be added to the synonymy of the species. 



Austrotriton parkinsonia (Perry, 1811). [P. 307.] 



Austrotriton Cossmann, Essai Paleconch. comp., vol. v, p. 98, 1903, was 

 proposed, with type the fossil T. radialis Tate, the species abbotti Ten.- 

 Woods and cyphus Tate being noted as congeneric. When Kesteven wrote 

 up his study of the genus Lotorum (= Fam. Cymatiidae mihi) (Proc. Linn. 

 Soc. N.S.W., 1902), he said (p. 484), " L. parkinsonianum is fche recent 

 representative of L. radiale, abbotti, &c. This group is more distinct than 

 any I have studied." Ten years afterwards (ib., vol. xxxvii, 1912) he 

 figured abbotti and parkinsonianum, as well as torterostris Tate, to show 

 the close relationship. 



The Recent species parkinsonia Perry stands quite alone when com- 

 pared with other Recent species, so that I make use of the generic fossil 

 name, basing its use upon Kesteven's studies. 



Triton strangei (A. Adams and Angas, 1864). [P. 308.] 



The reference " T. strangei Ad. & Ang., P.L.S., 1878, pi. 15, f. 16," must 

 be eliminated from the synonymy of C. spengleri. Pritchard and Gatliff
