216 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [510] 
common in the Bay of Fundy, &c. The Molgula producta (p. 502) also 
occurred on the sandy mud at the 29-fathom locality. 
The Echinoderms appear to be very scarce on these bottoms. The 
only one of special interest was the Molpadia odlitica, a small, round, 
rather slender species, about an inch and a half long, of a uniform flesh- 
color. Of this only one specimen was dredged, at the 29-fathom locality, 
fifteen miles east of No Man’s Land, by Dr. Packard, It had not been 
observed alive before, the only specimens previously known having 
been taken from the stomachs of fishes. 
The most interesting Hydroid that lives on the muddy bottoms is 
Corymorpha pendula, (Plate XXXVI, fig. 273.) This isa very beautiful 
species, which grows singly, with the bulb-like base of the stem inserted 
into the mud. 
Two interesting species of Polyps were found on the muddy bottoms. 
One of these, the Edwardsia farinacea, occurred only on the soft muddy 
bottom off Gay Head, in 19 fathoms. It is a cylindrical species, about 
an inch long, and .10 or .12 of an inch in diameter, remarkable for having 
only 12 tentacles, which are equal, unusually short, thick, and blunt. 
The coating of mud in the middle region is thin and easily removed. 
The single specimen obtained here had only 10 tentacles, but in other 
respects it agrees essentially with those found on similar bottoms at 
several localities in the Bay of Fundy, all of which had 12 tentacles. 
The body is whitish or flesh-color, the naked portion below the tentacles ; 
in the specimen from off Gay Head, was striped with 10 longitudinal 
lines or bands of brown, corresponding with the tentacles; these 
bands were varied with flake-white specks and mottlings, the spots of 
white becoming more distinct near the tentacles; these bands were 
alternately lighter and darker. Tentacles translucent at tip, tranversely 
barred on the inside, with about five brown bands and spots, the lower 
ones often V-shaped or W-shaped, and some of them extend around 
to the outside of the tentacles; alternating with these brown bands were 
bars and spots of yellow and of white. The disk was pale yellow, varied 
with small brown spots, mostly forming radiating rows from the mouth 
to the bases of the tentacles, and there were two spots of brown between 
the bases of adjacent tentacles ; mouth with ten lobes, which were also 
brown, with a fine light line extending from between them to the in- 
tervals between the tentacles. The specimens from the Bay of Fundy 
vary considerably in color, but the above is one of the more frequent 
styles of coloration. 
The Epizoanthus Americanus (Plate XX XVIII, figs. 286, 287) is a very 
singular species, which either lives attached to stones, as in the deeper 
parts of the Bay of Fundy and off Saint George’s Bank, in 430 fathoms, 
or else it attaches itself to univalve shells, inhabited by hermit-crabs. 
Allthose obtained in this region had the latter habit, and were from the 
29-fathom place, fifteen miles east of Block Island, on sandy mud. 
After one original young polyp has found lodgment and attached itself to 
the shell, its base begins to expand over the surface of the shell, and from
