Schizoporella auriculata, Hass. 
Loc. Living: European seas; Madeira; Azores; Gulf of 
St. Lawrence; Victoria; Green Point, Port Jackson, New 
South Wales. Fossil: Pliocene of Italy and Sicily; Mount 
Gambier and Bairnsdale (Australia); Napier and Tommy 
Gully (New Zealand). 
Schizoporella auriculata, Hass., var. 
There is also a Schizoporella which in most cases has only 
a round avicularium below the aperture ; but in a few zocecia 
there are besides two avicularia, one at each side of the aper- 
ture, as in S. sanguinea, Norman, var. (Hincks, Ann. & 
Mag. Nat. Hist. ser. 5, vol. vi. p. 382). The pores are small 
slits; and should it be requisite to give it a name, fiss¢pora 
would be appropriate; but as there are no ovicells, it is for the 
present left as a variety of auriculata. 
Schizoporella Cecilit, Aud. 
Mr. Hincks (Ann. & Mag. Nat. Hist.. ser. 5, vol. xix. 
p. 802) hesitates to identify this with Heller’s Lepralia Peru- 
gtana, as he considers that has an avicularium ; but Mr. Hincks 
is mistaken in supposing that Heller alludes to an avicularium ; 
what he described was the “ appendage ”’ of the operculum as 
a ‘kleines, gelbes Ziihnchen.” 
Loc. Britain; Mediterranean; Red Sea; Japan; Queen 
Charlotte Islands (British Columbia); Victoria; (Green 
Point, Port Jackson. Fossil: River-Murray Cliffs (South 
Australia). 
Schizoporella biserialis, Hincks. (PI. II. fig. 11.) 
Schizoporella biserialis, Hincks, Ann, & Mag. Nat. Hist. ser. 5, vol. xv. 
p- 250, pl. vii. fig. 3. 
In a specimen from Green Point the shape and size of the 
zocecia, the sculpturing, and the ovicells are just the same as 
in the New Zealand specimens; but there are numerous 
spines arising from the distal end of the zocecium, often as 
many as forty or fifty, and these do not seem to be arranged 
in series, though one might at first take them for three rows. 
The pores on the surface of the zocecia in the specimens 
from both localities are internally slightly denticulated. Schi- 
zoporella arachnoides, MacG., is probably nearly related to 
this; but the zocecia are smaller, the ovicell is elongate, there 
are not the large pores on the surface of the zocecia, and there 
is only a single row of oral spines.
