546 ON SOME NEW AUSTRALIAN BRACHYURA, 



internal angle for articulation with the fourth joint. Anterior 

 legs stout ; carpus with an acute tooth internally ; propodos 

 smooth, with a deep groove close to its lower border, at the 

 distal extremity ; upper finger also canaliculated externally. 

 Ambulatory legs rather short, smooth, and with a few hairs 

 above and below. Length iVths inch ; breadth J inch. 



Griffith's Point, Western Port, about five fathoms. 



Pararuppellia, n. g. (Farm Eriphiidae). 



Carapace as in Ruppellia. Basal joint of the antenna; 

 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. 



Pararuppellia saxicola, n. s. 



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. Chelipedes extremely large 

 and swollen in the male, carpus minutely granular and punctate, 

 with a few larger granules on its distal border, a strong tooth- 

 like process at its inner and distal angle ; propodos unequal, the 

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

 half the length, minutely granular and punctate above, jiunctato 

 alone below ; a row of punctations forming a longitudinal groove 

 on the lower and distal portion of the outer surface of the 

 propodos, continued on tho digital portion ; dactylos granular
