CRUSTACEA. 235 



two may be sexual. In two smaller examples from Balambangan 

 (male and female), in the collection of the British Museum, the 

 carapace is even more strongly granulated than in the adult, and 

 this is not uncommon in the Portunidse, e. g. in certain species of 

 Neptwnus. 



M. de Man has quite recently recorded this species from the 

 island of Amboina {vide Notes Mus. Leyden, y. p. 15-3, 1883). 



77. Kraussia nitida, Stimjison. 



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 differLng, as Stimpson has noted, only in 

 its somewhat narrower carapace, with more prominent and excavated 

 frontal lobes ; yet these distinctions are constant and easily perceived 

 in the specimens 1 have examined. 



Specimens referable to K. iniegra are in the Museum collection 

 from the Philippines, Siquijor {Cuming}, and also from the ' Sama- 

 rang ' collection without special locality. 



78. Te]j)husa (Geotelphusa) crassa ? 



? Telphusa crassa, A. M. -Edwards, Norm. Arch. Mus. Hist. Nat. v. 

 p. 177, pi. ix. fig. 2 (1869). 



■ A female in imperfect condition is in the collection, obtained at 

 Thursday Island, Torres Straits (No. 125), that I refer, though with 

 some doubt, to this species, as M. -Edwards's diagnosis is very short, 

 and the specimen figured of much smaller size than the one I have 

 before me. In this example there is a rudimentary epibranchial 

 tooth, the sides of the anterior part of the carapace are faintly 

 striated, shallow depressions indicate the anterior part of the 

 cervical suture, and the chelipedes are more unequal than in the 

 figure of M.-Edwards ; there is a strong spine on the inner margin 

 of the wrist, behind and below which is a second, much smaller 

 tooth ; the palm is nearly smooth ; the fingers longer than the 

 palm, vnth rather small denticulations and having between them, 

 when closed, but a small interspace. Length of carapace about 

 1 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 Mr. MacFarlane on one of the islands of Torres 

 Straits, which are apparently referable here. The smaller agree, 

 except in having some indications of a postfrontal crest, with the 

 description of Milne-Edwards ; but in the larger there exist much 

 more distinct traces of the exterior orbital and lateral epibranchial 

 teeth. In the male the fingers have between them, when closed, 

 but a small interspace.
