410 LIST OF LABRADOR MARINE ANIMALS. 



well in its generic character with H. Johnstonice Gray from New 

 Zealand, though differing specifically among other respects in 

 being multiserial. The coenoecium forms soft and flexible horn 

 colored tufts an inch in height. The cells in mature specimens are 

 arranged in several contiguous series and are very long, subclavate, 

 truncate, widening a little above, with sometimes a slight spine 

 on the outer angle. Tbe aperture is transversely linear and 

 closed by a slightly sinuate lid. The ovi-capsules are globular 

 and nearly smooth. The upper valves are so thin that in dried 

 specimens it readily contracts and the lid and linear aperture are 

 effaced, and the cell then appears as if it possessed a large, broad, 

 oval aperture, covered by a thin lid. 



A single branch consisted in one example of eight rows of cells. 

 A single isolated cell closely resembles a cell oiFlustra truncata, 

 showing the near relationship of this genus to the Flustradse. 

 But one tuft cf this interesting species occurred in 50 feet asso- 

 ciated with Beania admiranda, on a fragment of Pecten. 



Flustra truncata Linn. Frequent. 



F. membranacea Linn. Abundant. 



F. Murrayana Busk. ; 10-50 feet. Abundant. A common 

 species in Maine. 



Cellepora pumicosa Ellis. Frequent on sertularians. 



Gelleporaria surcularis n. sp. Grows two or three inches high, 

 branching dichotomously, the ends of the branches somewhat 

 truncated. Cylindrical, base two or three lines in thickness, 

 surface rough. Cells crowded, of unequal size, erect, conical. 

 Aperture small, with a slight sinus. In the young conical com- 

 munities, the cells stand out more from the axis ; apertures large, 

 round, with a slight, often obsolete, sinus. Surface of the cells 

 coarse, irregular and deeply punctured, often arranged in irregular 

 series running down the sides from the aperture. The terminal cell 

 large and conical. In old species the sinus is sometimes enlarged 

 with two denticles at its entrance. In section the cells are irregu- 

 larly oval, scattered thickly over the axis and periphery. 



Abundant on stems and cells in company with Escharse. 



Dr. Stimpson has placed in my hand specimens belonging to this 

 species, collected by Dr. Hayes in Northern Greenland, and by 

 McAndrew in Manseroe Sound, Finmark. European authors have 

 confounded this arctic species with C. cervicornis of the Mediter- 

 ranean sea, from whence it was originally described by Pallas. 



Eschara lobala Lamx. This species Lamoureux describes as
