200 Rev* T. Hincks's Contributions towards a 



Family Myriozoidae (part.), Smitt. 

 Schizoporella, Hincks. 



Schizoporella cinctipora y n. sp. (PI. VII. fig. 3.) 



Zooscia ovate, quincuncial, flattish, divided by raised lines; 

 surface reticulate, strongly calcified, glossy (the sheen due in 

 great part to the shining membranous covering of the reticu- 

 lations) ; orifice of about equal height and width, arched 

 above, lower margin straight, with a small rounded loop-like 

 sinus in the centre, the entrance guarded by two raised points ; 

 peristome much elevated and slightly thickened, forming an 

 enclosure round the primary orifice (which appears im- 

 mersed) ; close to the lower margin of the primary orifice at 

 one side a rather large round avicularium, placed on the sum- 

 mit of a low rounded mamilla, with smooth surface. 

 Ocecium rounded, broader than high, often subimmersed, sur- 

 face smooth and silvery or slightly roughened, with a number 

 of large circular punctures, the arch of the secondary orifice 

 carried across the front of it. 



Loc. New Zealand (Miss Jelly). 



Family Escharidae (part.), Smitt. 

 Lepralia, Johnston (part.). 



Lepralia foraminigera, n. sp. (PL VII. fig. 1.) 



Zocecia ovate (much irregularity in shape), quincuncial, 

 very slightly convex, sutures distinct but not deep ; surface 

 perfectly smooth, the front wall pierced by several foramina, 

 varying in shape, size, and disposition — sometimes of large 

 size, sometimes minute, the openings of which are closed in 

 by a chitinous membrane and have a slight edging ; orifice 

 broader than high, arched above, a constriction on each side a 

 short distance above the lower margin, which is curved out- 

 ward and very slightly prominent ; the oral operculum stout, 

 dense, and of a rather dark horn-colour ; peristome not ele- 

 vated. Avicularia none. Ocecium rounded, not prominent; 

 surface smooth, dense, waxy, the upper part occupied by a 

 large foramen with membranous covering. 



Primary (or central) cell expanded below, narrowing to- 

 wards the oral extremity, the whole area covered in by a 

 dark dense membrane ; no spines. 



Loc. New Zealand, forming large suborbicular brown 

 crusts (Miss Jelly) .
