 strongly resembles this species. 



5. Discoporella novae-zelandise, n. sp. (Plate XXX. fig. 2.) 



Discoid, cupped ; cells tubular, projecting, connate in uniserial 

 radii ; peristome bifid ; central area (unoccupied by cells) depressed ; 

 cancelli large, becoming smaller towards the periphery. 



Ilah. New Zealand, (? always) on a Catenicella (Dr. Lyall). 



A small species, rarely exceeding ^ inch in diameter. The much- 

 raised slender series of upright connate tubes with a bifid mouth, 

 and the comparatively very large central cancelli, are the main 

 characteristics of this abundant species. 



G. Discoporella flmbriata, n. sp. (Plate XXVII.) 



Zoarium almost conical ; cells very indistinctly serial, distant ; 

 interstitial pores almost obsolete ; mouth expanded ; peristome fim- 

 briated.

7. Discoporella californica, D'Orb. (Plate XXX. fig. 5.) 



Zoarium orbicular, thick, depressed in the centre ; cells disposed in 

 bi- to triserial radii, alternately longer and shorter, and much raised ; 

 cells connate throughout, thence hexagonal ; central area and inter- 

 serial spaces widely reticulate ; mouths of cells less than the cancelli.

Zoarium orbicular, convex, with the centre flat or depressed ; 

 cancelli small and sparse, not stellate. Cells connate, disposed in 

 much-raised uniserial rays alternately long and short ; mouths 

 obscurely raucronate. A single row of circular pores between the 

 rows of cells.
