CRUSTACEA. 295 



The rami of the uropoda are somewhat longer than the terminal 

 segment, 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, 4-6 fms. (No. 130), and is in very imperfect condition, the 

 right chelipede of the first and second pair and most of the ambula- 

 tory legs being deficient. Nevertheless the species may be distin- 

 guished from all described by Dana, Heller, or Stimpson by the 

 different dentition of the rostrum. On account of the minute dactyl 

 with its inferior tooth I refer this species to Coralliocaris ; but it 

 differs from the typical species in the slenderer maxillipedes and 

 shorter antennal scales. 



15. Palaeinon (Leander) intermedins, Stimpson. 



Three specimens, two of which are females with ova, were obtained 

 at Port Jackson, 0-5 fms. (first collection). Stimpson's specimens 

 were also from Port Jackson. 



Specimens are in the British-Museum collection from King 

 George'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, ex- 

 clusive of the subapical tooth on the rostrum, and more rarely seven 

 above and four below, as stated by Stimpson. The apex is usually, 

 but not invariably, bidentate ; in one of the specimens from Port 

 Molle the subapical tooth is placed further back on the dorsal 

 surface of the rostrum, which thus appears simple at its apex. 

 There is a small spiue at the base of the antennal peduncles outside 

 of the antennal scale. 



I regard the Palcemon (Leander) serenus of Heller*, from Sydney, 

 as very probably a mere variety of P. intermedins. Mr. Haswell 

 (Cat. p. 195) retains the two species as distinct ; but he appears to 

 have seen no specimens, and his translated descriptions are in- 

 accurate as regards the second pair of legs in both species. 



16. Sicyonia ocellata, Stimpson. 



A small specimen is in the second collection, from Thursday 

 Island, 1-5 fms. (No. 165), which agrees with Stimpson's descrip- 

 tion and the specimens in the British-Museum collection from Ceylon 

 and Hong Kong. To this species also belongs, I think, the Sicyonia 

 briefly characterized by Mr. Haswell, but without specific name, 

 from Port Jackson (vide Cat. p. 205). 



17. Penseus granulosus, Haswell. 



A small male from Port Darwin, 12 fms. (first collection), belongs 

 here, and also, I think, a male specimen from Thursday Island,
