136 "ENDEAVOUR" SCIENTIFIC RESULTS. 



In the larger specimen the posterior margin is straight ; 

 in the smaller one it is slightly convex; the two broad 

 teeth thus formed are very obtuse angled. As Miers says, 

 the largest of the lateral marginal tubercles is on the 

 postero-lateral margin; of the smaller tubercles one is at 

 the widest part of the carapace, forming a lateral angle, 

 and another nearly half way to the hepatic protuberance. 

 There is a suggestion of another tubercle in a slight marginal 

 swelling a little behind the lateral angle. The only dorsal 

 tubercle is that on the intestinal region in front of the 

 posterior spine.

PHILYRA MURRAYENSIS, sp. nov. 

 (Plate xxxiv.) 



Type-locality. Off Murray River mouth. South Aus- 

 tralia, 20 fathoms; E.4467; one adult female, holotype. 



Measurements. Female, total length of carapace 26, 

 length of median line from margin to margin 25, width 

 25.7 mm., posterior margin between tips of teeth 10.5, 

 anterior width between tips of subhepatic teeth 4.8 mm. 



Description. The edge of the buccal cavity shows very 

 slightly beyond the front, but the anterior end of the 

 subhepatic facet projects well beyond the outer angle of 

 the orbit in a thick, blunt, suberect tooth. The posterior 

 margin of the carapace is nearly straight and at either end 

 has a small acute tooth pointing backward. 



Carapace, subcircular, nearly smooth ; a furrow on either 

 side of the cardiac region, depressions behind the front and 

 each orbit ; surface obscurely granulate, granules depressed, 

 unequal, mixed with punctae. Sinus above cheliped broad, 

 obtuse angled. Four small lateral marginal tubercles, one 

 at posterior end of sinus, one over base of first ambulatory
