MARINE INVERTEBRATA OF GRAND MANAN. ' 51 



broadest below, as in A. appendiculosus, Kr. Antennae hairy, very short, the superior 

 ones very thick and tapering, equalling the inferior ones in length, that is, reaching 

 the second thoracic segment. Legs slender, very hairy, in structure like those of 

 the above species. Caudal stylets of the first two pairs long and pointed, slightly 

 serrated above, those of the last pair short, thick, and spinous. Color pale-whitish, 

 the brownish viscera showing through along the middle. Length, 0.35. Taken in 

 four fathoms, in sand, off Duck Island moorings ; in ten fathoms off Cheney's Head ; 

 and in twenty fathoms, mud and shells, off the northern point of Duck Island. 



A. EXIGUUS, St., n. s. Minute, compressed, but rounded on the back; last three 

 thoracic segments nearly equalling the first four in extent. Epimera of the first 

 four pairs equalling in height that of the segments which bear them. Abdomen 

 with its third segment tumid posteriorly, and curving downwards to the fourth, 

 thus forming a sinus, which appears deeper from a blunt projection on the middle 

 of the fifth segment. Head small, with the eyes bright red or vermilion in color 

 Superior antennae short and thick, about half the length of the very slender inferior 

 ones, which reach the fourth thoracic segment. Legs slender, in structure nearly 

 the same as in the above species. The posterior five pairs terminate in long slender 

 fingers. Basal joints of the posterior three pairs very broadly expanded, and deeply 

 serrated along their posterior edges. Caudal stylets as in A. politiis. Color yellow- 

 ish. Length, 0.2 inch. Dredged on sandy bottoms in 8-15 fathoms, east of the 

 Passage, and off Cheney's Head. 



STENOTHOE CLTPEATA, St., n. s. Body compresged ; epimera very large, especially 

 those of the fourth pair, which constitute great shields extending for a length equal 

 to that of three thoracic segments. Superior antennae short, curved, with long 

 flagella; inferior antennce long and slender, with very short flagella. External 

 maxillipeds very long, reaching up to the bases of the antennae. First pair of legs 

 slender, with small hands ; those of the second pair with very large hands, each of 

 which has two strong teeth on the lower edge, the basal one longest, and a stout, 

 curved finger. Legs of the fifth pair wanting the expansions of the basal joints. 

 Caudal stylets of the first two pairs biramous, subulate ; those of the third pair 

 simple, terminating in a thick sharp spine. Tail terminating in a minute elongated 

 scale. Natatory feet terminating in long slender lashes. Color, bright yellow ; in 

 the young, pale bluish. Eyes conspicuous, red. Length, 0.5 inch. Dredged in 

 thirty fathoms, on a shelly bottom in the Hake Bay. 



LEUCOTHOE GRANDIMANUS, St., n. s., Fig. 37. Large, robust, thick; epimera very 

 small; head depressed below the first thoracic segment, subquadrate, with a slight 

 rostrum in front, between the superior antennas. Eyes large, on the sides of the head. 

 Mandibles with minute, triarticulate palpi. Maxillipeds slender, freely projecting. 

 Superior antennae with very thick and elongated basal articles, and short flagella ; 

 inferior ones arising some distance below, and much more slender, but about as 

 long as the superior ones, which are in length about one-fourth that of the body. 

 In the first pair of legs the third joint is very minute, the antepenult subquadrate, 

 compressed, and with its inferior apex produced into a slender process, or thumb, 

 of equal length with the penult joint, which is very much elongated, slender, and
