CKTTSTACBA. 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 miUim.). 



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. Ifevertheless the species may be distin- 

 guished from aH 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 Goralliocaris ; but it 

 differs from the typical species in the slenderer maxUlipedes and 

 shorter antennal scales. 



15. Palsemon (Leander) intermedins, Stim/pson. 



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 Xing 

 George's Sound, S.W. Australia, and from Ovalau, Piji group 

 (F. M. Bayner, 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 spine 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. intermedius. 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, 4-5 fms. (JTo. 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. HasweU, but without specific name, 

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



17. Penaeus granulosus, Haswell. 



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

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