BRACHYOBA. RATHBUN. 115 



The specimens vary in size from the male (P.3519) 

 23 mm. long by 29 wide, to the young female (P.3569) 

 6.5 mm. long by 7.7 wide. 



The species may be recognised by its ragged appearance, 

 the carapace more than half smooth and naked, the long, 

 coarse, tubular hairs disposed in tufts on the anterior and 

 antero-lateral portions; besides there is a small tuft above 

 each posterior corner, and a still smaller tuft at each end 

 of the gastro-cardiac suture. The granules and tubercles 

 on the hepatic region are partially exposed. The upper 

 part of wrist and hand is almost bare and armed with large 

 tubercles; the distal half of the larger palm is also bare 

 and the tubercles well spaced. The ambulatory legs are 

 thickly clothed with hair on the upper margin, and in the 

 last pair on the lower margin, while the posterior surface 

 of the last two segments in all the legs is hairy.

Spencer Gulf, South Australia, 16 fathoms; E.4444; four 

 males, four females. The largest male is 9 mm. long, 13 

 wide ; the other specimens are considerably smaller. 



The species may be recognised by its short, thick, rather 

 smooth, furry coat in which are embedded the few red 

 granules, which to a certain degree retain their colour in 

 alcohol ; the large hand is half granulate, half smooth.
