MARINE INVERTEBRATA OF GRAND MANAN. 35 



middle teutacula, between the eyes, very long and curved; the lateral ones are 

 shorter. Tentacular cirri small. Branchite commencing on the fourth segment 

 from the neck, in the form of a slender process from the cirrus of the superior pinna, 

 which process forks on a succeeding segment, and becomes gradually more compli- 

 cated till the 13th segment. On this segment, and on those succeeding it to the 

 30th, the branchise are in the form of a beautiful comb of five slender processes, 

 reaching nearly to the middle of the back. At the 31st, they begin to decrease in 

 size and number of filaments, and leave only the dorsal cirrus at the 40th. Above 

 the base of this cirrus, on each segment, there is a black pigment spot under the 

 skin. The superior setge of the setiferous pinna are long and slender, the inferior 

 ones are short, and form a thick tuft. Inferior cirrus thick and short, but tapering. 

 Color light fawn or reddish with iridescence. Length, one inch + (the specimens 

 wanting the posterior rings) ; breadth, 0.1 inch. In its principal characters it 

 resembles E. Harassii, Aud. et M. Edw. Dredged in 20 f., on a shelly bottom, off 

 the northern point of Duck Island. 



EUNICE VIVIDA, St., n. s., Fig. 26. A large strong species. Body broad and 

 rather thick, rounded above, somewhat flattened below. Head with the middle 

 tentacle longest, reaching the sixth ring of the body from the neck ; the outer ones 

 scarcely reaching the- first ring. Tentacular cirri thick at base, pointed, reaching 

 as far as the eyes. Branchiae commencing at the first ring and ending at the 45th; 

 increasing and decreasing in complication as in the last species. The branchial 

 comb, where thickest, has nearly 20 closely arranged filamentary teeth. Pinnae 

 small, with very minute setae; dorsal cirri tapering to a fine point; ventral cirri 

 short, on thick globular bases. Color above cupreous. Length, 6 inches ; breadth, 

 0.26 inch. This species I at first thought to be the adult of E. Oerstedii, but the 

 proportionally smaller pinnae and setae seem to forbid. It is very active, and 

 almost as uneasy as a snake, in confinement, gyrating so rapidly and in such 

 curious circumvolutions as to threaten with destruction such unlucky invertebrates 

 as might be caught with it. 



ONUPHIS ESCHRICHTII, Oersd., Gronl. Ann. Dors., 20, pi. iii., f. 33-41, 45. Our 

 specimens are much smaller and more compressed than those of Oersted. It is finely 

 colored with red annulations on a bluish ground. The tube is broad, flat, and 

 composed of large angular fragments of shells and chips of slaty stones. Taken on 

 shelly bottoms in the coralline zone. 



CRYPTOIVOTA, St., n. g. 



Body broad, oval ; segments very narrow ; head minute, papilliform, placed at 

 about the anterior fourth of the length of the animal ; single median tentacle short, 

 much narrower than the head ; eyes two at the base of the tentacle. Back entirely 

 covered by the crowded dorsal setae, leaving only a median line of separation, which 

 terminates anteriorly at the head, and posteriorly not far from the margin. The 

 dorsal pinnae are thus transverse in the middle, and longitudinal at the extremities 

 of the body as if radiated from the two points forming the extremities of the
