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 avery small, scarcely distinct sinus on each side 
near the lateral angles (nternal 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
