Pilumnoplax heterochir, Miers, Challenger Kept., Zool., 

 xvii., 1886, p. 227, pi. xix., figs. l-ld. 



South of Gabo Island, Victoria, 200 fathoms; E.6211 ; 

 one male, two ovigerous females. 



South of Cape Everard, Victoria, 200 fathoms; E.6152; 

 one young male. 



Forty miles South of Cape Everard, Victoria, 200-270 

 fathoms; E.6155; two males, three ovigerous females. 



East-north-east of Maria Island, Tasmania, 127-180 

 fathoms; E.5168; one male, one female. 



Measurements. Largest male (E.6211), length of cara- 

 pace 8.2, width 11 mm. Largest female (E.6211), length 

 of carapace 9.3, width 12.8 mm. 



In all the specimens the right cheliped is the larger 

 except in the largest male. In comparing this male with 

 one 8.6 mm. wide or about the size of Miers 's figured speci- 

 men, the dark colour runs a little further back on the palm 

 in the larger one ; in all the males the colour margin is 

 oblique to the lower margin, not at right angles to it as in 

 Miers 's figure 16, and as in the female specimens. In the 

 young male (E.6152), 4.8 mm. wide, the granulation of 

 the major palm is much coarser than in larger specimens.
