358 APPENDIX. 



amplwra pass from the sides of the mouth to the apex of 

 the aviculariiim in front. One large specimen presents 

 a variety worthy of note — in this the backs of all the cells, 

 except one here and there, exhibit (internally ?) numerous 

 irregular- sized leopard-like spots. 



5. C. placj 10 stoma, n. s^. 



Cells short- ovoid ; a"^dcularia very large and long, ascend- 

 ing from near the bottom of the cell into an acute spinous 

 point, and supporting a deep cupped cavity ; mouth placed 

 obliquely; front of cell divided into fine large subtri- 

 ano'ular fenestrse bv foui^ broad bands. Back of cell with 

 a broad central band and two narrower bands branching 

 from it on each side ; surface of spaces left uncovered by 

 the bands on the back beset mth scattered, long setose 

 spines. 



Hab. — Bass Strait, 45 fathoms. 



Colour brownish white; habit stiff, branches short. 

 This species is at once recognisable by the peculiar oblique 

 position of the mouth — the enormously developed avicula- 

 rium usually only on one side of the cell, and by the 

 sculpture of the cell — which appears as if it were swathed 

 with broad tapes or bands. The wide spaces left between 

 the bands in front clearly represent the true nature of the 

 fenestrse of other species. It is the only species furnished 

 with elongated setose spines. 



6. C. lorica, n. sp. 



Cellar ia catenulata ? Lamarck. 



Cells elongated rhomb oidal, truncated at each end. 

 Fenestrse three, large, the lowest the largest, arranged in 

 a triangle. Mouth very large ; avicularia wide and strong ; 

 two lateral arese on each side, well developed ; surface in 

 front with a few indistinct circular spots around the fenes- 

 tree, and behind marked with faint longitudinal striae. 



Hab. — Bass Strait, 45 fathoms.
