For further synonymy and description see Suter’s Manual. It must be 
remembered that Suter mistook the anterior for the posterior of the shell, 
so his description of the beaks should read “ slightly curved backwards," 
on 
191—Shrimpton’s, Ngaruroro River, Hawke’s Bay. 
996—Kaawa Creek, Auckland. (Small specimens.) (Also collected 
by Bartrum. 
The lowest horizon in the Wanganui district recorded for this shell by 
Marshall and Murdoch is Nukumaru. 
Beyond the characters of the “ group,” this shell shows no close 
affinities with any other New Zealand shell, and, as the original stock 
by Oliver (1915, p. 567) in his list of mollusca from that locality. 
Species to be eliminated from New Zealand Lists. 
Glycymeris convexa (Tate). 
1885. Pectunculus convesus Tate, Trans. Roy. Soc. S. Aust., vol. 8, 
p. 138, pl. xi, fig. 7 a, b. 
1921. Glycymeris convexa (Tate): Suter, N.Z. Geol. Surv. Pal. Bill. 
No. 8, p. 49. 
The occurrence of this species in New Zealand strata is based on 
a single record (Suter, 1921, p. 49) from locality 449, Trelissick Basin. 
Strange to say, of the three shells in this collection, this particular speci- 
men is missing, so that no definite statement can now made as to its 
identity, and until this specimen is found, or further material collected, 
the Australian species cannot safely be said to occur in New Zealand. 
Glycymeris striatularis (Lamarck). 
1835. Pectunculus striatularis Lamk., An. s. Vert., vol. 6, p. 493. 
This is a Recent shell from King George Sound, Western Australia. It 
has been recorded doubtfully by E. A. Smith (1885, p. 252) from Port 
Jackson, but Hedley (1918) says the identification is erroneous. 
Hutton (1873, p. 28) and others used the name for the Wanganui and 
Recent shells now classed as G. modesta. Suter, while recognizing 
for these shells, has used striatularis in three other cases: (a) For speci- 
mens from Kaawa Creek (Bartrum, 1919, p. 104) belonging to the Axinea 
group, and very likely a young G. waipipiensis; (b) for small specimens
