EDWARDSIA FARINACEA Verrill. (p. 510.) 
American Journal of Science, vol. xlii, p. 118, 1866. 
Off Gay Head, 19 fathoms; Casco Bay, 10 to 70 fathoms; Bay of 
Fundy, 8 to 90 fathoms. 
EDWARDSIA LINEATA Verrill, sp. nov. (p. 497.) 
Body eylindrical, elongated, covered over the base and sides with a 
dirty, brownish, slightly rough and wrinkled epidermis, except anteriorly, 
below the tentacles, where it is smooth, translucent, and usually with 
eight impressed, longitudinal, flake-white lines, showing through, Tenta- 
cles, 24 to 30, or more, in the larger specimens, slender, tapering, obtuse, 
white or pale tlesh-color, each with a flake-white, longitudinal line along 
the inner side. Disk, with a white circle around the mouth, and often 
with 8,or more, radiating, white lines, extending to the base of the 
inner tentacles ; border of the mouth sometimes pale-red ; naked part 
of column pale flesh-color, often with a circle of white below the bases 
of the tentacles, and usually with eight oblong or fusiform flake-white 
spots between the longitudinal impressed lines. 
Length, 25™™ to 35™™; diameter, 2.5™™ to 3™™, A very young speci- 
men had 18 slender, equal, long tentacles, each with a median longi- 
tudinal line of white on the inside; disk with 6 radiating lines of 
white; naked’ part of the column with 6 impressed white lines, and 
with 6 oblong, flake-white spots between them. Breadth across the 
expanded tentacles, 3™™. 
This species is remarkable for not having, in any of the specimens 
found, a naked basal area, nor any true disk for attachment, thus differ- 
ing both from Phellia and the other species of Hdwardsia. This may be 
due to its peculiar habit of nestling in the crevices and interstices 
between rocks, ascidians, worm-tubes, ete. 
Off Watch Hill, Rhode Island, 4 to 5 fathoms, in cavities in and 
beneath Astrangia, ete.; Vineyard Sound and off Gay Head, 6 to 12 
fathoms, among ascidians, annelid-tubes, ete., abundant. 
Arachnactis brachiolata A. Agassiz. (p. 451.) 
Proc. Boston Soc. Nat. Hist., vol. ix, p. 159, 1862; Boston Journal of Nat. Hist., 
vol. vii, p. 525, 1863; Verrill, Memoirs Boston Soc. N. H., p. 33; Proceedings, 
vol. x, p. 343. 
Mr. A. Agassiz has recently ascertained that this is only a larval form 
of some species of Hdiwardsia. As it had already developed 16 tenta- 
cles, it must belong to one of the species having numerous tentacles 
when adult.
