—CRUSTACEA. 201upper face of the palms in oue (the largest) of the Shark-Bayspecimens.As there are in the British-Museum collection adult examplesundoubtedly referable to L. nodosus from Shark Bay, collected byLieut. Suckling, K.N., and presented by W. Wykeham Perry, Esq.,it is possible that L. intermedius may represent merely a youngcondition of this species.26. Lamhrus turriger, White.An adult male and female, in somewhat imperfect condition, arein the second collection, from the Arafura Sea, 32-36 fms. (No. 160).These specimens are certainly identical with specimens from thePhilipijino Islands {Cumimj) and Borneo (Admiralty), designatedL. turriger by White, although in the adult male received fromDr. Coppinger the spines of the carapace are considerably longerthan in the largest of these examples.Mr. Haswell mentions the occurrence of L. turriger at Darnley Island.As the description and figure of Adams and "White* give aninadequate idea of this very remarkable form, I subjoin the followingdescription of the principal specific characters, based upon an examinationof Dr. Cojjpinger's adult male :The cara{)ace is somewhat rhomboidal, constricted behind theorbits ;the front promiuent, triangulate, acute and deflexed, with asmall tooth or tubercle on each side near the base. The carapaceis armed with long spines, whereof one is situate on the gastric, one(very long) on the cardiac, and one (very long) on each branchialregion ; these spines are vertical ; there is besides a shorter spinebehind and in front of each of the branchial spines, and two, directedoblicjuely backwards, on the posterior margin of the carapace. Thechclipedes are very long, more than 4k times as long as the carapace,blender, and approaching more nearly to a cylindrical form than in anyother species I have examined ; the palm is scarcely more dilatedthan the wrist; and both arm, wrist, and palm are closely tuberculatedboth on their upper and under surfaces ; the anterior and jDosteriormargins are armed with longer tubercles or short spines, nearly asin the figure of Adams and White. In the smaller examples someof the shorter spines of the carapace may not be always developed,but the four long vertical spines of the gastric, cardiac, and branchialregions and the two spines of the posterior margin are alwaysdistinct.27. Lambrus hoplonotus, var. granulosus, Miers.Three specimens from Flinders, Clairmont, N.E. Australia, 11 fms.(No. 108, first collection), and one from Port Darwin, 12 fms.(second collection), agree more nearly with this variety than with anyother of this protean species, but exhibit a marked approach to var.longiocidis in the subspiniform tubercles of the gastric, cardiac, and* Zoology H.M.S.
