The raised lines are in one part of the specimen developed 

 to such an extent that the zooecia appear to grow out of a 

 common crust. 



Sraittia 7-ostriformis, n. sp. (PI. VIII. fig. 7.) 



Zoarium incrusting. Zooecia rhomboidal, hyaline, glisten- 

 ing, granulose ; primary orifice suborbicular, with three den- 

 ticles ; peristome vertical, with three tall spines ; one long 

 avicularium on each side, with long, slender, pointed mandible 

 nearly the length of the cell, margins of avicularian cell 

 serrate; on centre of anterior surface a small avicularium, 

 with triangular mandible pointing downwards; replacing one 

 of the lateral avicularia on some cells, a large avicularium 

 with thickly serrate margin and long hastate mandible. 

 Ooccia small, punctured ; on the front and upper part a curved 

 beak-like avicularium projecting vertically upwards ; orifice 

 of ooecium opening within peristome. 



Smiitia latiavicularia^ n. sp. (PL X. fig. 3.) 



Zoarium incrusting. Zooecia depressed, subimmersed, 

 white, granulose, not punctured, margins faintly areolated, 

 separated by raised lines ; primary orifice oblong ; one median 

 denticle (traces of rudimentary lateral denticles in a few cells) ; 

 peristome deficient posteriorly, rising on each side into a tri- 

 angular eminence, bearing on its outer side an avicularium 

 with acute mandible pointing forwards ; over front of zooecia 

 one or more shallow avicularia with spatulate mandibles. 

 Ooecium globose, punctured ; orifice surrounded by a rim 

 terminating above in a triangular area, supporting an avicu- 

 larium with pointed mandible. 



Smittia murarmata, n. sp. (PI. VIII. fig. 5.) 



Zoarium incrusting, covered by a thin, orange-tinted, 

 iridescent membrane. Zooecia oblong ; surface glistening, 

 granulose, areolated round the margins ; primary orifice 

 horseshoe-shaped, lower margin straight, with one very promi- 

 nent hammer-shaped denticle ; peristome raised, with wide 

 sinus in front, one lateral wall higher and longer than the 

 other; along the higher side of peristome an avicularian cell 

 with triangular mandible pointing upwards and forwards.
