 vol. xiv. p. 279, pi. ix. fig. 7. 



The fossil from Waipukurau has the upper part of the zooecium 

 raised, giving a tubular appearance to the peristome. The surface 

 is granular and has more punctures than are figured by MacGillivray. 

 The ovicell is narrower than a zooecium. In Mucronella canalifera, 

 Busk, the peristome is much produced and the ovicell is smaller. 



Loc. Living : Port Phillip Heads (Victoria). Fossil : Waipukurau 

 and Trig's Station.

A fossil from Napier is adnate. The zooecium is suboval, only 

 slightly convex, with rather large pores. Oral aperture elongate, 

 straight below and with the sides straight, curved above. Walls at 

 the side of the aperture thickened, forming a kind of peristome. 

 Above the aperture a nearty concealed ovicell with an oval cribri- 

 form depression in the middle. 



I am unable to rind any snboral avicularia, as described by Beuss, 

 and therefore call it var. simplex. 



The species is described from Sdllingen.

The fossil, though there are only the two upper openings, corre- 

 sponds with recent specimens ; the oral aperture, in each case, is 

 about 0*15 millim. in diameter, and the operculum has a character- 

 istic hinge-projection on each side, w 7 hich Mr. Hincks seems to have 

 overlooked.

55. Lepealia bistata, sp. nov. (Woodcut, fig. 1.) 



Zoarium incrusting. Zocecia distinct, convex, surface perforated 

 and mamillated. Oral aperture coarctate, with a small denticle at 

 each side where the contraction takes place. Ovicell small, subim- 

 mersed, about half the width of a zooecium, and the ovicelligerous 

 cells have a very much wider oral aperture than the other zocecia 

 and an extraordinarily thick lower lip. The zocecia and aperture 

 are about the same size as those of L. Pallasiana. 



Loc. Waipukurau Gorge.
