itean be properly used here. They recognised, however, that it 

 could not enter the genus Cycloxanthus, A. M. Edw. ( = Cyclox- 

 anthops, Rathb.) and transferred it to Lioxantho, Alcock. I 

 fail to see that it has any relationship here, and being unable to 

 refer it to any other known genus, propose a new one, Gabrielia 

 (ante) for its reception, together with Cycloxanthus punctatus, 

 Hasw., and C. carinatus, Baker. 



Port Phillip, Victoria. Dredged by Mr. J. Gabriel. 



Gabrielia punctata, Haswell. 



(Plate xii., fig. 4.) 



Cycloxanthus punctatus, Haswell, Proc. Linn. Soc. N. S. Wales, 

 vi., 1882, p. 752 ; and Cat, Austr. Crust , 1882, p. 50. 



Length of carapace about three-quarters of the breadth. The 

 regions are somewhat elevated, and the summits of either gastric 

 and epibranchial regions surmounted by a tuberculiform emin- 

 ence ; iuter-regional grooves deep and smooth. Scattered punc- 

 tations or pits on the anterior half of the carapace, becoming 

 very numerous behind. Front broadly rounded, equal to one- 

 half the width of the bod} 7 , and its upper surface somewhat 

 concave. Anterolateral borders strongly arched and divided 

 into four rather obscure lobes ; the first is the longest and least 

 distinct, and the second forms a hepatic angle. Postero-lateral 

 borders almost straight, strongly convergent. Under-surfaces of 

 the carapace and abdomen closely pitted everywhere, with the 

 exception of the front and sub-branchial portions. Orbits with 

 two indistinct sutures above, and a very indistinct one below. ; 

 lower borders minutely granular. 



Eyes smaller than in G. haswelli, with a small subapical 

 tubercle. 



External maxillipeds similar to that species, but much more 

 densely pitted. 



Chelipeds unequal ; the larger closely pitted on all its outer 

 surfaces, and smooth internally. Arm trigonal, its upper margin 

 denticulate. Wrist with an internal tubercle and a second 

 smaller one below it. Hand with a prominent crest on its upper 

 border, and a weaker one below, which is more pronounced on 

 the immobile finger ; also some indication of ridges on the outer 

 surface. Fingers each with four stout teeth on their inner 

 borders, which meet along their whole length and cross at the 

 tips ; mobile finger also crested. Smaller cheliped similar to the 

 larger, though smoother.
