Xaxia uries, McCulloch, Kec. Austral. Mus., ix., 1913, p. 327. 



A single male was taken on the east coast of Flinder's 

 Island, Bass Strait. It is a larger specimen than that 

 measured by Baker. 



Measurements. Length of carapace measured on median 

 line to posterior margin 37, greatest width of carapace, with- 

 out spines 26, length of rostral horn 9.2 mm. 



Subgenus MICROHALIMUS, Haswell.

 (Plate vii., fig. 3 and Fig. 3.) 



Type-locality. Great Australian Bight, south of Eucla, 

 Long. 129 <H' K., 200-300 fathoms. One ovigerous female, 

 holotype. 



Measurements. Length of carapace on median line 12.8, 

 length to tip of horns 16.5, width of carapace, 9mm. 



Description. Carapace pyriform, high in the middle, curving 

 rapidly down to the front and sides. Surface smooth and 

 sparingly clothed with long, fine, soft hairs. Cardiac region 

 faintly limited ; otherwise the dorsal aspect is without 

 inequalities. Rostrum about half as long as postrostral 

 portion of carapace, bifurcate about three-fourths of its 

 length, the horns slender, divergent, and probably acute, 

 although the tips are broken off. The preorbital spines are 

 about half as long as, but more divergent than, the rostral 

 spines. Postorbital lobes externally flattened in an oval face, 

 curved a little inward, tip blunt. Hepatic spines (one on 

 each side) directed forward, upward and a little outward, 

 laterally compressed, curved, acute, and reaching forward 

 to the level of the corneae. No branchial spine, but on the 

 sub-brr.nehial reeion two single tubercles followed a.nteriorly 



14. Lnppn. a burr, in allusion to the appearance of the i-arapar-e.
