58 MARINE INVERTEBRATA OF GRAND MANAN. 



straight, spine-like terminal articles. Antenna?, epimera, and legs all hirsute with 

 plumose seta3. Caudal stylets all biramous ; those of the third pair with the 

 internal rami much shorter and more slender than the outer ones. Tail terminat- 

 ing in two short lamella?, in length one-half that of the last caudal stylets. Color 

 white. Length, 0.2 inch. Dredged on coarse sandy bottoms, in the laminarian 

 and coralline zones. It has more nails on the third and fourth legs than P. plumo- 

 siis, Kr. 



P. Kroteri, St., n. s. Larger, and thicker than the preceding, glabrous above, 

 and of a pale-red color, with the eyes white. The antenna?, legs, and epimera are 

 all very hairy, but the hairs are simple instead of plumose. Superior antennae 

 shorter and more slender than the inferior ones. Mandibles with palpi almost as 

 long as the superior antenna?. Legs of the first pair with more elongated hands 

 than in the preceding species; those of the sixth jiair not so long in proportion. 

 Third and fourth pairs with simple terminal nails. Tail terminating in two sharp 

 spines. Length, 0.3 inch. Taken at low-water mark, on a sandy shore, at High 

 Duck Island. It resembles most P. Holhollii, Kr. 



STOMAPODA. 



Mysis oculata, (?) Kr. A species of Mysis is very abundant in the waters at the 

 mouth of the Bay of Fundy, swimming near the surface in swarms, and generally 

 far from land. They form almost the only food of the herring, wliose stomachs 

 may alwaj's be found distended with this kind of food. It is particularly numerous 

 in what are called the " Ripplings," which take place on the flood-tide at a line of 

 shoals several miles east of Grand Manan ; which form the chief fishing-ground of 

 the herring-catchers. 



DECAPODA. 



Pandalus levigatus, St., n. s. This large species differs from P. horeaUs, Kroyer, 

 in the want of dorsal spines on the third and fourth abdominal rings, and in hav. 

 ing only eleven superior spines or serrations on the rostrum, which are situated 

 only on the posterior two-thirds of its length. Its color is usually a very pale 

 yellow, with narrow blue lines on the back. Dredged on rocky bottoms in the 

 laminarian zone. 



Hippoltte aculeata, Gould, Inv. Mass., 332. Very common in the laminarian 

 zone. It is beautifully mottled with bright red, with some white or bluish spots. 



Crangon vulgaris, Fabr., M. Edw., Gould, Inv. Mass., 331. Taken, not com- 

 monly, at low water, in sheltered, sandy coves. 



C. BOREAS, Phipps. This fine species was dredged in four fathoms, on a nullipore 

 bottom, near the Passage, and in twenty fathoms, shelly, off Duck Island ledge. 



HoMARus Americanus, M. Edw., Hist. Nat. des Crust., ii. 334. The lobster is 

 said by the inhabitants to occur in great numbers in May, at Grand Harbor, living
