A contribution to American thalassography; three cruises of the United States Coast and geodetic survey steamer "Blake," in the Gulf of Mexico, in the Caribbean Sea, and along the Atlantic coast of the United States, from 1877 to 1800. Blake (Ship); Marine animals -- Atlantic Ocean; Marine sediments; Ocean. 50 THREE CRUISES OF THE " BLAKE. species in the " Blake " collection, and half of them were new. The largest species is Colossendeis colossea (Fig. 254), in which the slender legs are nearly two feet in extent, and the rostrum more than an inch long, while the more slender Colossendeis 'macerrima spreads to fourteen inches, and has a rostrum fully as long as in the larger species. These species were taken in 500 to 1,200 fathoms. The new genus Scseorhynchus (Fig. 255) is remarkable for its spiny body and swollen and reflexed rostrum; the legs of S. armatiis (Fig. 256), the single species taken below 1,200 fathoms, are nearly five inches in length. The most abundant species of Nymphon is also the largest known species of the genus. One of the species of the new genus Pallenopsis, dredged from 260 to 330 fathoms, is more than twice as large as any of the species from allied genera belonging near the shore or in comparatively shallow water. There is a great contrast between the life ,of the communities of barnacles, such as we find living crowded on our rocks and floating on the surface, and that of the comparatively solitary deep-sea cirripeds Scalpellum, Verruca, and the Uke. This is readily understood when we remember that the living or dead organic matter floating on the surface in the wake of currents, and along the shores, supplies the former with a large amount of food, while the conditions of life at the bottom are far from favorable for the sjDecies living in deep water. The abyssal cirripeds are usually attached to nodules, to dead or living shells, to corals, large crus- taceans, spines of sea-ur- chins, and the like. Sccd- Fig.
