231 COLLECTIONS FROM MELANESIA.and is separated by a triangulate norch from the rounded fourthlobe or internal orbital angle. The basal joint of the antennas isarmed with a minutely granulated or denticulated ridge. Themerus-joint of the anterior legs has four spines on its anteriormargin, including a very small spinule at its antero-internal angle ;the wrist has a strong spine on its inner margin and two smallspinules on its outer surface ; and the palm (as in G. affine) hasfive spines on its upper surface, the two anterior being very small.The fifth ambulatory legs have a strong spine, situated nearly at thedistal end of the posterior margin of the merus-joint, and anotheron the posterior margin of the carpus ; the flattened terminal jointhas a small spinule at its distal extremity, but is otherwise unarmed.From the preceding species, to which it is very nearly allied,G. sphiiferum is distinguished by the greater transverse width ofthe carapace, the different form of the frontal lobes and of theirintervening fissures and of the lateral teeth (see the figure). GoniosomaheUerii, A. M.-Edwards *, from New Caledonia, which resemblesthis species in having five spines on the upper surface of the palm,and the merus-joint of the fifth ambulatory legs armed with astrong distal spine, differs in the form of the carapace and frontallobes, and has the penultimate joint of the fifth ambulatory legsdenticulated on its posterior margin, &c.75. Nectocarcinus integrifrons (Latr.).There are three females of this species in Dr. Cojjpinger's collection,from Port Jackson, 0-7 fms. (Nos. 90, 104).A specimen from the same locality is in the British-Museumfrom the collection of Mr. Cuming, and another dredged in thesame harbour on the Sow and Pigs Bank, and presented by JohnBrazier, Esq. ; also from Port Curtis (H.M.S. ' Herald') andNew Zealand, Bay of Islands (Antarctic Expedition) ; also fromOceania {J. Macr/illivrai/, H.M.S. ' Rattlesnake') ; and others withoutspecial locality.Dr. Kinahan records it from Port Phillip, Victoria.76. Lupocyclus rotundatus, Adams c}- White.A female is in the collection from Port MoUe, Queensland (firstcollection. No. 118), and another from Fridaj' Island, 10 fms. (secondcollection. No. 153), wbich I think must be referred to this species,although the carapace is somewhat broader, more convex, and lessdistinctly granulated, and the frontal lobes more acute than in theadult specimen in the British-Museum collection from Balambangan,N. Borneo, on which presumably the description of Adams andWhite was founded.As the Bornean example is a male, the distinctions between the* Bull. Soc. Entom. de France, rii. p. 282 (1867).
