LIST OP LABRADOR MARINE ANIMALS. 411 



growing in radiating patches, always adhering to the surface of ob- 

 jects, and collected near the Bank of Newfoundland. Cells oblong, 

 oval, convex ; each end is connected with the cell in front and 

 behind, with a few larger emaginate punctures. Aperture round 

 with a shallow broad sinus. Just behind the aperture a small 

 perforated conical eminence, which in old specimens bears a large 

 avicularium, with long sharp pointed beaks gaping widely; or when 

 absent the cone is large, covering the upper surface of the cell 

 and furrowed with descending ridges. In communities with ovi- 

 capsules, the surface of the cell itself cannot be seen ; the cap_ 

 sules are globular, sublunate in form, with emarginated-punctures • 

 the aperture large, often truncate behind. Cells arranged in linear 

 series with intervening ridges. 



Occurs spreading over dead Cardium and Serripes in 10-20 feet 

 Salmon Bay, or in 50 feet on the Banks. I have taken it in the Bay 

 of Fundy from low water mark at Eastport to 20 feet. 



It is very different from a thin, fiat, membranaceous, inverted 

 cup-shaped species that inhabits Massachusetts Bay. 



E. elegantxda D'Orby. The coenoecium of this fine species grows 

 several inches high in erect branching masses, the branches 

 expanding flat and spreading at the ends. Cells broad, oval flattened, 

 somewhat produced at the base; surface smooth, sub granulated* 

 Aperture round, with a broad shallow sinus. Young cells often 

 margined with a row of large punctures. In old communities 

 the ovi-ce!ls are narrow-oblong, very convex, semi-cylindrical 

 the cylinder-like avicularia projecting over the aperture, and 

 perforated with a large operculated aperture. Towards the end 

 of the branches, the cells are somewhat cylindrical bearing narrow 

 globular ovi-capsules, which are emarginate-punctured. This is 

 near Busk's E. saccata which came either fromNorway or Finraark. 

 It differs however from his figure ; and his rather unsatisfactory 

 description does not aid me in determining the species. 



Common on the Bank in company with Cellepora. I have spe- 

 cimens also from the Newfoundland Banks. Dr. Stimpson has 

 also specimens collected in Northern Greenland by Dr. Hayes in 

 his last expedition. 



Myriozoum subgracile D'Orby. (Fig. 5.) (Millepora truncata 

 Linn. Fabr. F. G.) Frequent with the other species. 



Fabricius' description applies well to this species. It grows two 

 or three inches high, branching dic.hotomously ; branches cylin- 

 drical, smooth, while at irregular distances slightly contracting, — -
