BRACHYORA. RATHBCN. 113 



Chelae somewhat unequal, covered with a fine but dense 

 granulation reaching nearly to the tips. The horny tips, 

 to which the long hair extends, are in the case of the 

 movable finger only one-fifth of the length of the whole 

 finger. The specific name draws attention to this 

 peculiarity. 



Ambulatory legs shorter than in trichophorus and 

 trichophoroides, the penultimate leg being less than twice 

 as long as the fronto-orbital distance.

Type-locality. Twelve miles north-north-east of Bowen. 

 Queensland, 19-25 fathoms; E.3155; one male, holotype. 



Measurements. Male holotype, total length of carapace 

 11.6, total width 13.5, fronto-orbital width 9.4, width of 

 front 5 mm. 



Description. A narrow species without spines, clothed 

 with uneven, ragged-looking hairs. Carapace covered with 

 short and rather fine hair, also long, coarse hair disposed 

 in a line behind the front, a bunch on each protogastric 

 region and a larger patch near the margin at the widest 

 part of the carapace. "When, the hair is removed, the 

 hepatic region is seen to be marked off by a wide furrow, 

 the epigastric regions are isolated, the protogastric regions 

 are continuous with the broad part of the mesogastric 

 region, the median furrow, including the narrow part of 

 the mesogastric region, is deep, the epibranchial lobe is 

 raised, the lateral teeth are separated off in a sort of rim. 

 All the most elevated parts of the carapace including the 

 frontal, epigastric, middle part of protogastric, hepatic 

 and epibranchial lobes, also the antero-lateral teeth and 

 the postero-lateral regions are granulate. 



The large lobes of the front are broadly rounded, median 

 notch of good size, lateral notches larger, the outer teeth 

 slightly acute. Inner upper angle of orbit almost obsolete. 

 Margins of front and orbit granulate, one well-marked 

 superior orbital notch, a shallow notch below outer angle, 

 a thick, triangular tooth at lower, inner angle. Suborbital 

 and subhepatic regions very finely granulate ; 110 sub- 

 hepatic tooth nor spine. Four antero-lateral teeth, the first 

 low, second largest, carapace equally wide at the third and 

 the fourth tooth.
