MARINE INVERTEBRATA OF GRAND MANAN. 31 



depressed line commences, running on the remaining length of the body. The 

 branchiae are on the first two segments. The neck is provided with a ring of eye- 

 spots, numerous and variable in size, under the labia of the tentaculiferous disk. 

 On the 22d segment, at the right side, just above and behind the superior pinna, 

 arise two long tube-like cirri, which in one of my specimens are filled with eggs (?). 

 It inhabits a tube of a thin leathery structure. 



I at first considered the animals above described as immature, on account of the 

 presence of eyes at the neck; as Prof. Agassiz states such to be the case in young 

 specimens of his Terebella fulgida. (See Bost. Proc., iii. 191.) But having, among 

 many specimens, observed none larger or further developed, and considering most 

 of the remaining characters above mentioned as important, I have been led to 

 propose a new genus for the reception of the species. 



LUMARA FLAVA, St., n. s. Of a bright-yellow color; branchiae with 6-8 rami, and 

 a few short processes on the sides of their rings. Length one and a half inch ; 

 breadth, 0.11 inch. Tubes thin, of a light-yellowish color, usually with pebbles 

 attached to the outer surface. Dredged in 35 f. in the Hake Bay. 



TEREBELLA BRUNNEA, St., n. s. This species is large, of a uniform, dark, reddish- 

 brown color; segments about 56; aciculae of the anterior feet rather short; the 

 ventral shields on the first eight segments oblong, transverse, and rather narrow. 

 Tentacula large and very numerous, brownish ; branchiae in three pairs, with 7-12 

 rami to each, those of the first pair being most numerous. Length about five 

 inches ; greatest breadth three-tenths of an inch. It inhabits thick-walled tubes, 

 formed of mud and sand, which are found in great numbers on the under surfaces 

 of large stones, near low-water mark. 



The uncinate setse in this species are very variable in shape. They are of the 

 same type as those of T. parvula, Leuckart, as figured in Wiegm. Archiv, 1849, 

 Taf. iii. f. 6, but are much more elongated and projecting above. 



T. CIRRATA, Cuv. Leuck., 1. c. This species differs from the preceding in its 

 smaller number of rami in the branchiae, in the rhomboidal shape of the last ventral 

 shields, and in the bright-yellow color of the anterior ventral surface. The unci- 

 nate setaa conform generally to the same type as those of T. brunnea, and though 

 they have sometimes slight denticles besides the upper frontal tooth, I have never 

 met with any precisely like those of T. cirrata figured by Leuckart (1. c., fig. 5). 

 The aciculaa are longer than those of the preceding species, and widened near their 

 extremities, which taper to fine hair-like lashes. My specimens are about three 

 inches in length, with nearly seventy segments. They were all found in deep 

 water, chiefly on shelly bottoms, in 20-40 fathoms. 



CLYMENE LUMBRICALIS, St. (non Aud. et Edw.) Sabella lumbricalis, 0. Fabr., F. 

 G., p. 374. Tubes adherent to stones, shells, etc., in deep water. 



MARIGOLD. 



ARENICOLA PISCATORUM, Cuv., Regne Anirn., etc. Common on sandy shores above 

 low-water mark, especially where there are scattered boulders. 



SIPHONOSTOHUM ASPERUM, St., n. s. Body slender, thickest anteriorly behind
