408 LIST OF LABRADOR MARINE ANIMALS. 



L. Belli Dawson. Frequent. 



L, labiata Stm. One group of this singular species occurred. 



L. Utieata Hassell. Rare. 



L. globifera n. sp. Cells large, fiat, white, the surface some- 

 what raised around the small round aperture, which has a slight 

 sinus. Behind the sinus is a minute perforated conical avicularium. 

 Ovi-cell large, globose, with a few emarginated coarse punctures. 

 Cells in radiating lines, with ridges running between them. The 

 ovi-capsules are more crowded in the centre of the patch, not 

 being present in the inner cells. Frequent, forming frosty white 

 patches. It often encrusts Celleporse, where the ovi-cells are 

 much crowded, and the ridges between the radiating rows of cells 

 obsolete. I have dredged it in the Bay of Fundy. 



Stimpson's L. Candida, very common in the Bay of Fundy, did 

 not occur in my collection. 



Membranipora pilosa Johnst. Especially abundant encircling 

 fronds of Desmarestia just below low-water mark. 



M. lineata Busk. 



M. Lacroixii Busk ? I cannot distinguish these two species 

 from Greenland specimens. 



M. solida n. sp. (Fig. 2.) Cells large', fiat, solid, oval angu- 

 lated, often presenting a six sided figure as is common in the genus. 

 Margin raised, simple, very broad and without spines. Aperture 

 occupying one half of the upper surface, transversely broad, oval, 

 with a broad deep sinus ; the posterior half of the upper valve is 

 thin, convex subrugose, with a small, triangularly perforate, conical 

 avicularium, situated at the posterior end of the upper surface. Cells 

 arranged in lines, or in quincunces, or more often irregularly. The 

 cells are not so crowded as in the other species. To the naked 

 eye it looks like bleached patches of old worn Lepralise. 



Beania admiranda n. sp. Cells very large, erect, oval 

 smooth, base produced, sessile. Growing in tufts, the cells arrang- 

 ed in contiguous series, the new cells arising on each side of the 

 aperture of the parent cell. Aperture raised, circular, surmounted 

 by two long stout truncate spines, which are succeeded on the 

 opposite side by two i;ows of long obtuse spines nearly meeting 

 across the hollow formed by the two ridges on the back of the 

 cell. Compared with B. mirabilis of the British coast, this is a 

 much stouter species, growing in low spreading, but not creeping 

 tufts. There are from 6 to 8 pairs of large obtuse spines which meet 

 across the cell ; being fewer in number, and longer and stouter
