;208 COLLECTIONS FROM MELANESIA.37. Galene granulata. (Plate XX. fig. A.)Carapace narrower in proportion to its length than Galene bispinosa,Herbst, the whole of the upper surface granulated, thegranules, however, somewhat unevenly disposed ; the cervical andcardiaco-branchial sutures are distinctly defined. In G. hispinosa(Herbst) the carapace is granulated only near the lateral margins.The two median teeth of the front are distinctly developed, but thetwo lateral teeth (those over the inner orbital hiatus) are obsolete ;these teeth are very distinct in Galene bispinosa (Herbst). Theantcro-lateral margins have three distinct tuberculiform teeththere are but two developed in G. bispinosa ; the palms of thechelipedes are granidated over the whole of their outer surface,whereas in G. bispinosa the granulations exist only at the base,near the articulation with the wrist.Of G. granulata there is but one specimen in the collection, asmall male from Port Darwin, 7-12 fms. (No. 173).The characters enumerated above, important though they mayappear, may possibly be found to be dependent on the age and sizeof the specimen, the length of whose carapace is only 5g lines(11^ millim.), less than one fourth of the Length of an adult exampleof G, bispinosa from Singapore (A. R. Wallace) in theMuseum collection, and which is the only specimen I have examined;but I do not feel justified in uniting the two forms in the absenceof any specimens with transitional characters. Both the specimensof G. bispinosa and of G. granulata are imperfect, that of G. bispinosahaving lost the postabdomen, and that of G. granulata all exceptone of the ambulatory legs.38. Halimede ? coppingeri. (Plate XX. fig. B.)In this curious little species the carapace is anteriorly somewhatdeflexed, with the antero-lateral margins somewhat shorter thanthe postero-lateral ; body and legs are alike covered with a closevelvety pubescence. The sulci defining the regions of the carapaceare indistinguishable ; the carapace is tuberculated, the tuberclesrather large, and ai'ranged in rather irregular transverse series.The front is divided by a median notch into two rather prominentrounded lobes, on either side of which the exterior angles form lessprominent teeth. The upper orbital margin has a large blunttubercle behind the outer frontal lobes. The antero-lateral marginshave four very distinct tuberculiform teeth, the first of which issituated immediately behind the exterior angle of the orbit. Theepistoma is transverse, the pterygostomian regions without spinesor tubercles. The postabdomen in the female has all the segmentsdistinct. The eye-peduncles are short and robust ; the antennulesnearly transversely folded ; the basal antennal joint reaches beyondthe subfrontal process, and thus enters within the inner orbitalhiatus ; the two following joints are slender ; the flagellum filiformand rather long. The merus-joiut of the outer maxillipedes is, as
