bles Phillipsastrcea ; but the obtuse, flattened, or depressed polygonal 

 calices with numerous fine radiating lamellae, which meet or are 

 continuous with those of adjoining corallites, separate it from that 

 genus. The absence of solid partitions or boundary-walls removes 

 it from the compound Strephodes, and it differs from Sarcinula in not 

 having the distinct septate corallites. Our specimen is a wavy ex- 

 panded mass ; the corallites circular, small, and steeply edged, irre- 

 gularly scattered over the surface, with well-defined styliform colu- 

 mellae or axes ; the margins of the calices are slightly elevated above 

 the plane of the anastomosing lamellae, resembling some Isastrcuce. 

 Diameter of cells about 1 line. Base not seen ; probably it was con- 

 centrically rugose.

The hexagonal cells, with rather thick walls and wavy tabulae, 

 and the alternately long and short septa or lamellae, reaching about 

 halfway from the wall to the centre of the calice, clearly define 

 this species. 



Dr. Sutherland collected his specimens at Cape Riley, Barrow's 

 Straits, in lat. 74° 40'. Captain Feilden obtained his at Franklin- 

 Pierce Bay, Walrus Island, and Cape Hilgard, lat. 79° 41', 5° fur- 

 ther north than Dr. Sutherland.

This must have been a large coral, composed of elongated poly- 

 gonal tubes mostly agreeing in size, and of equal diameter on the 

 surface. The septa or lamellae are almost obsolete ; tabulae very 

 closely arranged and not quite horizontal. 



We possess only a fragment or two, but enough to distinguish 

 them to be F. Franklini, Salter, as figured in the above reference.

At first sight this specimen resembles Favistella, especially in the 

 vertical section ; but the calices are round or slightly subangular 

 when polished, certainly not polygonal as in Favistella ; again, there
