A single male specimen was collected at Elphinstone Island. 



The cephalothorax of this little species is 8 millim. long and 

 123 millim. broad, very convex longitudinally and transversely ; 

 the upper surface is glabrous, smooth, though minutely punctate 

 on the cardiac region and the surrounding parts of the middle of 

 the carapace, and minutely granular on the frontal and antero- 

 lateral regions. These minute points and granules, however, 

 are only visible with a magnifying-glass, so that the upper surface 

 appears smooth and shining to the unaided eye. Some inter- 

 regional grooves are very faintly indicated, while the others 

 are entirely absent: thus a faint longitudinal median groove is 

 observed on the anterior part of the carapace which separates 

 the two scarcely distinct epigastric lobes; the transverse groove 

 between the gastric and cardiac regions is also feeble, whilst a 

 curved minutely granular line occurs on each side of the carapace, 

 proceeding from the last antero-lateral tooth obliquely forward, 

 as indicated in the figure in the ' Archives.' 



The front is not at all prominent but a little deflexed, and its 

 straight anterior margin presents only a small narrow median 

 incision and a very small, scarcely distinct sinus on each side 

 near the lateral angles (internal orbital angles). The upper 

 margin of the orbits is unarmed and presents no fissures; but the 

 under margin presents a triangular hiatus near the external 

 orbital angle, and is armed in the middle with a series of four or 

 five small conical granules, between which some smaller ones 

 occur ; the under orbital margin also appears to be a little hairy 

 The antero-lateral margins of the carapace are much shorter 

 than the straight postero-lateral ones ; they are armed with four 

 teeth, including the external orbital angles. The first tooth, the 

 outer angle of the orbits, is broadly truncate ; the second is a little 

 narrower, but likewise rather obtuse; while the third and the 

 fourth teeth are acute and directed obliquely forward. (In
