Zocecia large. eloDgate, ovate, quincuncial, very distinct, con- 

 vex, sutures not very deep; surface dense, punctured (the 

 punctures often obliterated by the calcification ; orifice sub- 

 erect suborbicular, with a broad rounded sinus occupying nearly 

 the whole of the lower margin ; peristome raised and thickened, 

 forming a wall round the orifice, often massive in front, where it 

 is carried out into a broad projection, which is notched or sinu- 

 ated in the centre. Avicularia none. Ooecium large, rounded, 

 broader than high, with rather large punctures. 



Loc. Houston-Stewart Channel, Queen Charlotte Islands 15-20 

 fms. (^Dr. G. M. Dawsoii). 



SCHIZOPORELLA LONGIROSTRATA, N. SP. 



Zocecia ovate, disposed in lines, moderately convex, (sutures 

 shallow) ; surface roughened or minutely granulated, covered 

 with an epitheca ; orifice arched above, lower margin extended 

 into a wide rounded sinus; peristome thin, elevated at each side; 

 on one side, generally a little below the orifice, an elongate, 

 slender, pointed, dependent avicidarimn, the mandible (which is 

 broad at the base and tapering above) directed obliquely down- 

 wards, usually turned slightly outwards. Ooecium rounded flat-

 sutures shallow ; surface vitreous, glossy, thickly covered over its 

 whole extent with punctures ; orifice arched above, the lower 

 margin almost entirely occupied by a wide very shallow sinus; 

 peristome thin, moderately raised, extended in front (beyond the 

 sinus) so as to form a small chamber, in which is a rounded 

 orifice (? aviculariuni). Ocecia profusely developed, very 

 large (covering about two-thirds of the cell above), elongate, 

 rounded above, with a tall oral arch, thickly covered with 

 slightly granulated ridges, which radiate from the opening to 

 the base.
