[739] INVERTEBRATE ANIMALS OF VINEYARD SOUND, ETC. 445 



EDWAKDSIA FABINACEA 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 cylindrical, 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 flesh-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 mm to 35 mm ; diameter, 2.5 mm to 3 mm . 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 rnm . 



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 Edwardsia. This may be 

 due to its peculiar habit of nestling in the crevices and interstices 

 between rocks, ascidians, worm-tubes, etc. 



Off Watch Hill, Ehode Island, 4 to 5 fathoms, in cavities in and 

 beneath Astrangia, etc. ; Vineyard Sound arid off Gay Head, G to 12 

 fathoms, among ascidians, annelid-tubes, etc., 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 Edivardsia. .As it had already developed 16 tenta 

 cles, it must belong to one of the species having numerous tentacles 

 when adult.
