Art. LVII.—Notes on some New Zealand Crustaccans. By T. W. Kirk, Assistant in the Colonial Museum. [Read before the Wellington Philosophical Society, 11th January, 1879.] Squilla, Fabr. Squilla armata, M. Edw., Hist. Nat. Crust., II., p. 521; Gray, Hist. Chile, Zool., Vol. III., Crust., p. 223; Trans. N.Z. Inst., Vol. X., p. 474. Several very fine specimens of this species were recently obtained in Wellington Harbour. At the same time a specimen was procured differing from S. armata in having a high median crest on the carapace; no spines on the ophthalmic segment; only five spines on the terminal joint of the prehensile limbs, and a nearly square rostral plate. The specimen is much broken, the whole of the thoracic segments are missing. Length about 5 inches. Squilla indefensa, Mihi. A third specimen of this species was shown to me a short time since; it was procured at Waikanae by Mr. J. Taylor, a student of the Wellington College, and is now preserved in the Museum of that institution. Calocaris, Bell. Calocaris macandreæ, Bell; Brit. Crust., p. 231. Two specimens of this remarkable Crustacean were obtained by myself a few weeks since, on the Otaki beach, near the wreck of the ‘City of Auckland.’ Although they must have been lying on the sand for some hours at least, one of them showed distinctly the delicate pink colouring mentioned by Prof. Bell in his description. Callianassa, Leach. Callianassa. sp. ind. A specimen undoubtedly referable to this genus has been obtained by Mr. H. B. Kirk, at Island Bay. The carapace is much broken; right claw the largest. Total length, 1 ⅝ inch. Gebia, Leach. Gebia hirtifrons, Dana; U.S. Explor. Exped., XIII., Crust., part I., p. 511. A specimen in the private collection of Mr. H. B. Kirk appears to belong to this species. It measures 2 ½ inches in total length, “the hand slender, hairy, and not denticulated below; the wrist has a spine at its upper apex and one on the inner margin, but none at the lower apex;” legs hairy; “front hardly, if at all, three-lobed.” The specimen agrees well with the figure of G. hirtifrons, in the Zoology of the Voyage of H.M.SS. ‘Erebus’ and ‘Terror.’

There are also in the collection specimens agreeing well with the description of G. danai, Miers. Portunus, Leach. Portunus pusillus, Leach, Malac. Brit., t. IX., f. 5–8; Edwards, Nat. Hist. Crust., I., p. 444; Bell, Brit. Crust., p. 112. Three specimens agreeing well with Prof. Bell's description are in the Colonial Museum; the only difference being that the New Zealand specimens have a prominent spine on the anterior margin of hand. Female, length, 5/10 inch; breadth, 6/10 inch. Male, length, 4/10 inch; breadth, 5/10 inch. Hab.: Cook Strait. Podocerus, Leach. Podocerus cylindricus, Say, Jour. Acad. Philad., I., part 2; Edwards, Hist, des Crust., III., p. 64; Cat. Amp. Crust. B.M., p. 256. Three specimens were obtained at Worser Bay, in tangled seaweed. Pleustes, Spence Bate. Pleustes panoplus, Kroyer, Grön. Amf., p. 42, pl. 2, f. 9; Edwards, Hist. des Crust., t. III., p. 41: Cat. Amp. Crust. B.M., p. 63. Seven specimens at same time and place as last species. These, are both arctic species, and their occurrence on our coast is somewhat remarkable.
