7-4 AUSTRALIAN HALACOSTRACA. 



No fissures nor teeth on the superior and inferior borders of 

 the orbit. Front much inclined downwards, less deeply toothed 

 than in R. tenax, and marked with a small transverse groove ; a 

 small horizontal crest on the teeth of the antero-lateral borders 

 of the carapace ; anterior legs smooth. Length ten lines ; 

 Colour whitish, with rose-coloured bands on the legs. [M.-Edw.'] 



"Woodlark Island, Louisiade Archipelago. 



The present specimen agrees in all points with Milne-Edwards' 

 description (except that the colouring is entirely lost) ; it differs 

 from Dana's figure in having no distinct line running inwards 

 from the last tooth of the antero-lateral margin. 



Grenus Pararuppellia, Haswell. 



Carapace as in Rv/ppellia. Basal joint of the antenna 1 

 extremely short, not nearly reaching the front; second joint 

 stout, touching the front ; flagellum entirely excluded from the 

 orbit by the union of the lower orbital border with the front. 



128. Pararupellia saxicola. A.M. 



Pararupellia saxicola, Haswell, 1. c. 



Carapace convex, very minutely granular. Front prominent, 

 sex-dentate, the two median teeth more prominent and much 

 broader than the lateral, truncate. Orbital margin finely 

 granular ; upper border with two fissures, an obtuse lobe at its 

 inner end ; outer angle with two blunt teeth ; lower border with 

 a rounded lobe near its inner angle. Antero-lateral margin thin, 

 granular, divided by two wide notches into three low broad lobes, 

 of which the first is the narrowest and the second the broadest ; 

 behind this a prominent acute tooth directed forwards and 

 outwards, its anterior border continued on the carapace as a, 

 granular ridge for a short distance. Anterior legs extremely 

 large and swollen in the male ; wrist minutely granular and 

 punctate, with a few larger granules on its distal border, a strong 

 tooth-like process at its inner and distal angle ; hands unequal, 

 the larger (in the male) longer than the carapace, the breadth 

 about half the length, minutely granular and punctate above, 

 punctate alone below ; a row of punctations forming a longi- 

 tudinal groove on the lower and distal portion of the outer 

 surface of the hand, continued on the immobile finger ; mobile
