The Bahama Expedition obtained about 66 species of Ophiuroidea, among which there are many species of great interest and several that were previously unknown. In former years the same region had been very extensively explored by the various dredging expeditions made by Mr. Alexander Agassiz, in the Coast Survey Steamer Blake, and by other earlier government expeditions. The various collections thus obtained were very fully worked up and the numerous new species were described by Mr. Theodore Lyman in the publications of the Museum of Comparative Zoology. The Challenger Expedition added a few species from the same region, which are included in Mr. Lymans final report on the Challenger Ophiuroidea (Vol. V, 1882). Therefore, it was not to have been expected that many new discoveries would be made, in that region, by a comparatively small number of dredgings, and with a far less elaborate equipment. Hence the number of new forms obtained by the Bahama Expedition is rather surprising. Bulletin of the Mus. Comp.

V--1 A This collection is peculiar in lacking many common species which were taken at numerous stations and in large numbers by the Blake Expedition. Such species belong largely to such genera as Ophioglypha, Ophiomusium, Amphiura, etc. These live, for the most part, on muddy or sandy bottoms, or buried just below the surface, and are only to be obt. . .
