420 Mr. E. T. Giintlier on above and one below. The number of gills could not be definitely ascertained^ but there are five -well-developed pleurobranchs and a single series of rudimentary arthro-branchs, as well as a series of epipods ceasing apparently on tbe third last leg. All the thoracic legs bear exopods, and the first two pairs are chelate. Spence JBate^s family Carycyphirlse*, being founded entirely on immature forms^ cannot be sustained. It seems not unlikely that some at least of the species are lai'val Acanthephyridse, and in the present instance the arrange-ment of the gills lends some support to this view. Distribution. Various forms referred to the " genus '^ Caricyphus were taken by the ' Challenger ' in the Pacific, and by tbe Plankton Expedition in the Atlantic, in all cases at or near the surface. Family Paguridse. Locality. Lat. 52°4'-5 N., long. ll°20'-l W. Net no. 1 b. 20 fath. 19/11/98. One specimen. This specimen is a zoea-larva at a stage in whicb none of the abdominal appendages are yet developed, although the telson bears seven pairs of spines instead of six as in the first stage of the Pagurid zoea. It differs from the zoea of Eupagnrus bernhanius as described by Sars f in the shorter rostral spine and in the broader telson, the posterior margin of which is straight, not incised in the middle as in the earlier stages of that species, nor convex as in Anapayurus chiroacantlms.

Guxther, M.A., Fellow of Magdalen College, Oxford. [Plates IX. &X.] Although a great deal of care was bestowed upon the collection and preservation of the material presently to be described, it was not easy to refer some of the individual specimens to their proper place in the system.
