or Bortonian beds at Black Point and Kakahu. The d Point beds Leg 
been doubtfully referred to the Piripauan by Thomson (Trans. N.Z. Inst., 
vol. 52, 1920, p. 385), and the only stage at present “distinguished Sar 
Bortonian and Piripauan is the Kaitangatan. The Kartigi and Moeraki 
beds therefore presumably represent the Kaitangatan and Bortonian stages, 
so that the “ boulders " are probably of low Eocene age ; in the absence of 
fossils, further speculation is useless. 
Ditrupa chapmani n. sp. (Fig. 2, a, b, c, d.) 
Tube rather long and very slender, gently tapering; perfect juvenile 
specimens have very much the appearance of Cadulus delicatulus, being of 
about the same proportions but slightly less curved and of different texture. 
The curvature is distinct but not great, more pronounced posteriorly. No 
tes 
and rather regular growth-lines, Pin rings that are always fine Еа 
pale brown with rings and bands of greyish. The cross-sections of bro 
specimens show that the internal orifice is always circular, but may be саа 
or distinctly excentric; there is an inner narrow whitish ring, then a thick 
brownish crystalline layer with a radiating appearance, then finally a very 
narrow surface-layer.

Type, Мез Clifden, Southland (band 6c—Ototaran ?), in author's collec- 
tion. Most plentiful and of best preservation in this band, but occurring 
also in several ei) bands at that locality. 
Of much egant appearance, greater tenuity, and more gradual 
taper than р cornea var. wormbetiensis MeCoy, typical examples of that 
species being considerably shorter, yet much wider than the new species. 
The absence of anterior nodosities separates it at once from the var. constricta 
Chapman. Named after Mr. Chapman, of the National Museum, Melbourne, 
who has always readily given his assistance on this and other occasions. 
. Serpula ouyenensis Chapman. 
Described from the оек (?) and Janjukian of the Mallee Вогез, 
Victoria (Proc. Roy. Soc. Vict., vol. 26, n.s., p. 182, pl. 18, figs. 24, idi pl. 19, 
fig. 42; 1913). Mr. Chaya identified as this species specimens of a 
Serpula from the road-cutting at Pukeuri (Awamoan) ; € shell is is quite 
common at that locality, but the specimens are exc y fragile, and 
es small pieces can be obtained. Specimens that seem also referable 
this species are commonly found in several of the bands at Clifden, 
Southland, but more especially band 6c. This horizon is considerably 
lower than Awamoan, and may well be Lower Miocene or even Oligocene, 
so that the species would seem to have an earlier occurrence in New Ze 'aland 
than in Australia, and, if the Australian records are included, a considerable 
range. This, however, is of frequent occurrence in the Annelids.
