SFIDEK CKABS. RATHBUN. 21 



Cape Marsden, Kangaroo Island, South Australia. 17 

 fathoms ; one immature female. 



Off Marsden Point, Kangaroo Island, 17 fathoms ; one 

 male and one ovigerous female, the latter very old and en- 

 crusted with mollusks (Anomia ?) serpulid tubes, and one 

 stalked barnacle. 



Great Australian Bight, south of Eucla, Long. 12U 28' K., 

 250-450 fathoms ; one young, very small. 



The specimens agree very well with Haswell's description 

 and figure. The spinules of the dorsal surface are numerous, 

 unequal, but none of them much enlarged. As to the border 

 spines, the spine projecting from the preorbital lobe is trans- 

 verse and its tip turns slightly upward ; middle spine of orbit 

 spinulous ; outer spine directed forward, acute, and armed on 

 the outer edge with two smaller spines ; two hepatic spines, 

 nearly transverse and subequal, the anterior usually a little 

 the larger : a semicircle of four spines on the branchial region, 

 the last one standing well in on the carapace : in the intervals 

 between these spines there is a smaller spine or spiiiule, any 

 of which may be suppressed ; two small submedian spines on 

 the intestinal region. The marginal spines are proportionally 

 larger in the young than in the adult. 



The ventral surface is especially setose in the females and 

 young, but a transverse band at the articulation of ischium 

 and merus of outer maxilliped is always naked and smoothly 

 rounded. The externo -distal angle of the ischium projects 

 laterally in a small spine. While the different segments of the 

 male sternum bear concavities, they are not deeply guttered. 



A small orange -red spot on the outside of the chela at 

 articulation of propodus and dactylus persists in the pre- 

 served specimens. 



Measurements. The largest specimen, an egg-bearing ? 

 (E 809) is almost entirely concealed by a mass of shells and 

 worm tubes. It measures, roughly, 136 mm. long and 118 

 wide. 



This species may be the L. gaimardii of Milne Edwards 20 of 

 which a full description and figure are lacking. Filhol 81 says 

 that the posterior of the marginal hepatic spines of L. gaimardii 

 is bifurcate, and the series of large branchial spines numbers 

 five.
