Report on the zoological collections made in the Indo-Pacific Ocean ...

CRUSTACEA. 235two may be sexual. In two smaller examples from Balambaugan(male and female), in the collection of the British Museum, thecarapace is even more strongly granulated than in the adult, andthis is not uncommon in the Portunidae, e. g. in certain species ofNejytunus.M. de Man has quite recently recorded this species from theisland of Amboina {vide Notes Mus. Leydeu, v. p. 153, 1883).77. Kraussia nitida, Stimpson.Two small specimens (males) from Thursday Island, 4-5 fms.(No. 165), evidently belong here.The distinctions between this species and K, integra (De Haan),are very slight, K. nitida differing, as Stimpson has noted, only inits somewhat narro^yer carapace, with more prominent and excavatedfrontal lobes ;yet these distinctions are constant and easily perceivedin the specimens I have examined.Specimens referable to A', intcgra are in the Museum collectionfrom the Philippines, Siquijor {Cuming), and also from the Samarang' 'collection without special ' locality.78. Telpliusa (Geotelphusa) crassa ?? Telphusa crassa, A. M.-Echvards, Nouv. Arch. Mus. Hist. Nat. v.p. 177, pi. ix. fig. 2 (1869).A female in imperfect condition is in the collection, obtained atThursday Island, Torres Straits (No. 125), that I refer, though withsome doubt, to this species, as M. -Edwards's diagnosis is very short,and the specimen figured of much smaller size than the one I havebefore me. In this example there is a rudimentary epibranchialtooth, the sides of the anterior part of the carapace are faintlystriated, shallow depressions indicate the anterior part of thecervical suture, and the chelipedes are more unequal than in thefigure of M.-Edwards; there is a strong spine on the inner marginof the wrist, behind and below which is a second, much smallertooth ; the palm is nearly smooth ; the fingei's longer than thepalm, with rather small denticulations and having between them,when closed, but a small interspace. Length of carapace about1 inch 4 lines (35 millim.), greatest breadth 1 inch 4 lines(45 millim.).There is a series of four specimens in the Museum collection,obtained by My. MacEarlane on one of the islands of TorresStraits, which are apparently referable here. The smaller agree,excejjt in having some indications of a postfrontal crest, with thedescription of Milne-Edwards ; but in the larger there exist muchmore distinct traces of the exterior orbital and lateral epibranchialteeth. In the male the fingers have between them, when closed,but a small interspace.
