which forms a wall about '12 of an inch high around the linear month,

The specimens of this species have not been found in the collection 

 and its generic cliaracters are doubtful. 



Phellia Panamensis Verriii, sp. nov. 



A large species, with the column much elongated, subcylindrical, 

 or enlarging upward, capable of great extension or of contracting 

 into the form of a tall cone by involving the summit ; surface entirely 

 covered, except on a narrow band below the margin, with a thick and 

 firm mud-colored epidermis, which is thrown into fine, close, irregular 

 wrinkles, the intervening spaces appearing like small, irregular papil- 

 Ieb. Naked space below the margin smoothish in full expansion, more 

 or less corrugated and with papilliform wrinkles in partial contraction. 

 Tentacles about 96 in number, the 12 inner ones large and stout, much 

 larger than the others, which decrease gradually in size to the outer 

 ones, which are quite small and crowded at the margin. In dissecting 

 a large specimen, it was found that the 12 septa corresponding to the 

 12 large inner tentacles, are much larger than the others, with the 

 inner edges strongly thickened and muscular, and bear the large con- 

 voluted ovaries throughout nearly their whole length, while the inter- 

 venino- small septa are very narrow, not thickened, and bear no sexual 

 oro-ans. Color in life unknown. In alcohol the column is mud-colored, 

 except near the margin, where it is white. Height of the largest 

 specimen, partly contracted in alcohol, 3 inches ; diameter 1. Another 

 specimen is 3 inches high and -5 in diameter. 



Panama,— F. H. Bradley. 



This laro-e and fine species is known only from alcoholic specimens, 

 most of which have the disk and tentacles expanded.

Arctic Ocean, north of Behring's Straits, in 30 fathoms, — North 

 Pacific Expl. Expedition. 



This species grows to a pretty large size, and is remarkable for 

 havino-, in the only specimen seen, peculiar ova-like bodies imbedded 

 in the surface of the column.
