SCHIZOPORELLA FISSURELLA, N. SP. 



Zocecia small, quincuncially disposed, ovate, the lower portion, 

 flattish ; oral rc<rion raised, tubular, subereet; surface smooth, 

 porcelanous, shining, sutures extremely shallow; orifice im- 

 mersed, arched above, straight below, with a narrow slit-like 

 sinus ; peristome thickened and elevated round the mouth, so as 

 to form a kind of neck, carried out in front into a mucronate 

 process, which is sometimes notched in the centre. Zowcumi 

 rounded, smooth, with a small longitudinal fissure above the 

 opening, a central tooth-like process just within the oral arch.

LEPRALIA BILABIATA, N. SP. 



Zooecia quincuncially arranged, short, very slightly convex 

 (the sutures little more than incised lines), rounded above, 

 widening out at each side and narrowing off towards the base, 

 which is subtruncate : surface dense, smooth, of a somewhat 

 waxy appearance ; orifice large, occupying nearly half of the 

 front surface, rounded above, very slightly contracted imme- 

 diately above the lower margin, which is somewhat arched ; 

 peristome not elevated ; operculum smooth, of a deep black 

 color, distinctly bilabiate. Avfcularia none. Ocecium a sub- 

 triangular extension of the cell above the orifice, very little 

 raised, a great part of its front surl'aee occupied by a large fora- 

 men, closed in by membrano-chitinous material. 



Zoarlum of a very dark brown color (almost black). 



Loc. Houston-Stewart Chanr)el. Queen Charlotte Islands, on 

 shells (Z)/-. G. M. Dawmn). 



When the zoarium is open, the orifice is occupied in great part 

 by the entrance to a tubular passage (through which the poly- 

 pide issues), which is formed hefoiv by the thickened border of 

 the operculum, and (iIm/cc by a distinct chitinous rim. These 

 two lips are brouglit together so as to close the entrance when, 

 the operculum is shut. 



LEPRALIA NITESCENS, N. SP. 



Zooecia quincuncial, short-ovate, very ventricose ; surface 

 dense, vitreous, highly polished and glistening, smooth, with 

 obscure radiating ridges, punctured, sometimes areolated round 

 the maruin : orifice much higher than broad, immersed in the
