Cymatium suteri M. & M. ; 
Th hor is of opinion that this species is a Xymene, and so should 
not be included in the Cymatiidae. 
Cymatium pahiense M. & M. 
This is a peculiar species, and, as noted by the authors, is unsatis- 
factorily placed in Cymatium. If it belongs to this family at all, the 
strong posterior notch would seem to bring it nearer to the Bursidae, but 
the general appearance of the shell is somewhat like that of a Cassid. At 
present its position must be regarded as quite uncertain. 
Charonia lampas (L.). 
Septa rubicunda Perry: Suter, Man. N.Z. Moll., p. 303. 
Charonia lampas var. euclia Hedley. 
C. nodifera var. euclia Hedley, Biol. Res. “ Endeavour," vol. 2, 1914, p. 65. 
Iredale (Trans. N.Z. Inst., vol. 47, p. 458, 1915) has united the species 
rubicunda, nodifera, and sauliae, and gives the oldest name as C. lampas (L.). 
The author has obtained (by trawling outside Otago Heads in 22 fathoms) 
one fine adult shell that agrees almost exactly with Hedley's figure and 
description of the var. euclia. Ali the Australian specimens were dredged 
in very much deeper water. 
Argobuccinum tumidum (Dkr.). 
A, argus (Gmel.): Suter, Man. N.Z. Moll., p. 309. (See Hedley, Proc. Linn. 
Soc. N.S.W., vol. 38, p. 297, 1913.) 
Mayena australasia (Perry). 
Argobuccinum australasia Suter, Man. N.Z. Moll., p. 310. 
Iredale (Proc. Mal. Soc., vol. 12, p. 324, 1917) has proposed the generic 
name Mayena for this species and gemmifera (Euthyme). In the same place, 
however, he noted that Bartsch had classed the South African species in 
Eugyrina Dall. Hedley (Proc. Roy. Soc. N.S.W., vol. 51, p. 66) has reduced 
ayena to a synonym of Eugyrina; but May (Check-list of the Mollusca of 
Tasmania, рр. 64—65, 1921) has employed both genera, retaining Mayena for 
ustralasia, a course which is adopted here. Suter (Alph. List N Z. Tert. - 
Moll., 1918) records only this species and C. spengleri of our Recent species 
as fossil in the New Zealand Tertiary. 
Priene retiolum Hedley (Biol. Res. “ Endeavour,” vol. 2, p. 73, 1914). 
This rare deep-water species should be admitted to the New Zealand 
Recent fauna, one broken specimen having been found by the author at 
Taieri Beach, South Island, washed up on the rocks. It presents an 
appearance so dissimilar to Argobuccinum tumidum (Dkr.), the genotype of 
Argobuccinum, that Priene is heré given generic rank. 
Cymatium parthenopeum (von Salis). 
Septa costata (Born): Suter, Man. N.Z. Moll., p. 305. 
Iredale (Trans. N.Z. Inst., vol. 47, p. 459, 1915) has advised use of the 
above name for this shell, and has placed it under Cymatium in the sub- 
genus Monoplez, referring C. exaratum (Reeve) and C. spengleri (Perry)
