CEXTSTACEA. 295The rami of the uropoda are somewhat longer than the terminalsegment, ovate, the outer somewhat broader than the inner. Colour(in spirit) purplish brown. Length about 7| lines (16 millim.).The single specimen, a female with ova, was obtained at Thursday-Island, 4-0 fms. (No. 130), and is in very imperfect condition, theright chelipede of the first and second pair and most of the ambulatorylegs being deficient. Nevertheless the species may be distinguishedfrom all described by Dana, Heller, or Stimpson by thedifi'erent dentition of the rostrum. On account of the minute dactylwith its inferior tooth I refer this species to Coraliiocaris ; but itdiffers from the typical species in the slenderer maxillipedes andshorter antenna! scales.15. Palsemon (Leander) intermedius, Stimi^son.Three specimens, two of which are females with ova, were obtainedat Port Jackson, 0-5 fms. (first collection). 8timpson's specimenswere also from Port Jackson.Specimens are in the British-Museum collection from KingGeorge's Sound, S.W. Australia, and from Ovalau, Fiji group{F. M. Rayner, H.M.S. Herald ' '), and also from Tasmania.This species usually has eight teeth above and five below, exclusiveof the subapical tooth on the rostrum, and more rarely sevenabove and four below, as stated by Stimpson. The apex is usually,but not invariably, bidentate ; in one of the specimens from PortMoUe the subapical tooth is placed further back on the dorsalsurface of the rostrum, which thus appears simple at its apex.There is a small spine at the base of the antennal peduncles outsideof the antennal scale.I regard the Palcvmon (^Leander) serenus of Heller*, from Sydney,as very probably a mere variety of P. intermedius. Mr. Haswell(Cat. p. 195) retains the two species as distinct ; but he appears tohave seen no specimens, and his translated descriptions are inaccurateas regards the second pair of legs in both species.16. Sicyonia ocellata, Stimpson.A small specimen is in the second collection, from Thursday-Island, 4-5 fms. (No. 165), which agrees with Stimpson's descriptionand the specimens in the British-Museum collection from Ceylonand Hong Kong. To this species also belongs, I think, the Sicyoniabriefiy characterized by Mr. Haswell, but without specific name,from Port Jackson (vide Cat. p. 205).17. Penaeus granulosus, Hasivell.A small male from Port Darwin, 12 fms. (first collection), belongshere, and also, I think, a male specimen from Thursday Island,* •Reise der Novara,' Crust, p. 110, pi. x. fig. 6 (1805).
