Descriptions of New Species of Fossils 



Ceramopora raripora n. sp. 



Bryozoiim growing in thin expansions ; celluliferous on one side 

 (so far as observed), the other side marked by a wrinkled epitheca. 

 Cell-tubes subcylindrical, oblique, enlarging to the aperture, extremely 

 variable in size. Apertures from .5 to 1.5 mm. in diameter ; arching 

 and subtriangular in form, and arranged in alternating and imbri- 

 cating series ; the larger cells frequently appearing polygonal and 

 opening directly upward. 



This species differs from the preceding in the closer arrangement 

 of the cells, comparatively little of the cell-tube being seen, and 

 also in the larger cell-apertures, which open directly outward. 



Ceramopora (Paleschara ?) nothus n. sp. 



Bryozoum growing in thin expansions, attached to other organic 

 bodies ; cell-tubes short, arranged in alternating and imbricating 

 order : aperture arched or angular, usually oblique to the plane of 

 the surface, sometimes opening obliquely upward, one-third of a 

 millimetre in diameter. Surface marked by numerous slightly 

 elevated maculae, the centres of which are distant from each other 

 about four or five mm. These maculae are occupied by larger cells, 

 their apertures being nearly a half millimetre in diameter. 



In well-preserved specimens, the angles of the cell-apertures have 

 short, spine-like projections. 



This species resembles C. confluens ; but the cell-apertures are 

 larger, and the maculae are less elevated and always covered by cells. 

 In C. agellus the cell-tubes are more exposed and have a radiating 

 order not observed in this form. 



EscHAROPORA (Ptilodyctia) angusta n. sp. 



Bryozoum an elongate, simple stipe, celluliferous on both sides : 

 cell-apertures opening a little obliquely upon the surface, about five 

 in the width of the stipe, occupying a width of 1.3mm., while in the 

 same space longitudinally there are three. Margins of stipe granulose. 



Fenestella pertenuis n. sp. 



Frond flabelliform, branches slender, from eight to eleven in the 

 space of five mm. ; on the non-poriferous side the branches are 

 flattened and striated, the striae distinct, from three to five on a
