BIUCHYUKA RATHBUN. 135 



East of Bass Strait, 70-80 fathoms; E.4821; fourteen 

 males, eight females (two ovigerous). 



Twenty miles east of Babel Islands, Bass Strait, 65-70 

 fathoms; E.5160; seven males, twenty females (eight 

 ovigerous). 



East of Babel Islands, Bass Strait, about 70 fathoms; 

 E.5192; two males, six females (two ovigerous). 



Sixty to eighty miles west of Eucla, Great Australian 

 Bight, 80-120 fathoms; E.3170; two females. P.3556 ; one 

 male. 



Total length of male carapace (E.6484) 9.3, width 9 mm. 

 Length of female (E.5160) 7.8, width 7.7 mm. Length 

 of smallest ovigerous female (E.6484) 5.5 mm. 



Variation. Whitelegge (loc. cit.) mentions the varia- 

 bility in the granulation. Besides the varieties which he 

 observed we have some specimens, part of E.4821, in which, 

 regardless of sex, all the granules of the carapace are flat 

 and disc-like, but many of them are as if crowded up to a 

 higher level, making a very uneven surface. As a rule 

 the carapaces with this surface have higher and rougher 

 protuberances, while the smooth, evenly paved carapaces 

 have low, smoothly rounded protuberances which more 

 often in the female than in the male, may be almost obsolete 

 on the branchial regions. Milne Edwards (loc. cit.) may 

 have described such a specimen, as he does not mention 

 branchial tubercles. 



Regardless of the above characters, the posterior lobes 

 are shallow in the female, protuberant in the male.
