Parthenii G-iannettaiii Eol. 1 . No. 91. JULY 1885. I. — On some Deep-sea and Shallow-water Hydrozoa. By John J. Quelch, B.Sc. (Lond.), Natural History Museum. [Plates I. & IL] The forms described in the present paper consist chiefly of deep-sea Hydroida which were obtained by Mr. G. A. Bishop while engaged in repairing the cable off the Cape Verde Islands. With the exception of the variety oi,DipJiasia pinas-ter ^ which was taken by Mr. Bishop from the Madeira cable off Lisbon, and the specimens of Gryptolaria conferta presented by Miss M'Lea, the Hydroida were taken by Mr. Bishop from the cable off S. Antonio, the depth being, as Mr. Bishop assured me, over 500 fathoms. Though but a very small collection, yet the forms obtained are of great interest, since they belong, with but one exception, either to new or rare species, and throw considerable liglit on the classification of their allied forms. As a contribution to our knowledge of the Hydroida at great depths the collection is a valuable one, while the many points which it serves to elucidate in the characters of structures which had hitherto been imperfectly known or altogether misunderstood give to it a special interest. A definite contribution is thus made to our know-Ann. & Mag. N. Hist. Ser. 5. Vol xvi, 1
