STUDIES IN AUSTRALIAN CRUSTACEA — McCULLOCH. 347 



Clibanariua, sp., Whitelegge, Proc. Hoy. Soc. N. S. Wales, xxiii., 

 1890, p. 23*2, No. 358. 



Anterior portion of carapace much longer than broad, almost 

 smooth, but with more or less numerous minute pits ; a few tufts 

 of long seta? on the sides and behind the cervical groove. Rostrum 

 triangular, acute, projecting a little beyond the antennal angles, 

 which are broad and without terminal spines. Eye-stalks slender, 

 as long as or longer than the width of the anterior portion of the 

 carapace, and a trifle longer than the antennular peduncles. 

 Ophthalmic scales close together, their outer margins rounded 

 and finely denticulated. Antennal scales with long setae ; 

 their bases each with a single external spine, and five or six 

 on the anterior portions, which reach to or slightly beyond the 

 penultimate joints of the peduncles. Flagellum reaching well 

 beyond the chelipeds. 



Chelipeds equal and similar, with very long seta*. No spines 

 on the arm above, but one or two at their infero-external ex- 

 tremities ; lower internal margin with a row of spiniform 

 tubercles, the inner and outer surfaces with slightly raised 

 white prominences of varying size, which are largest anteriorly. 

 Wrist with three spines on its upper margin increasing in size 

 forwards ; outer surface with or without one or two pointed 

 tubercles and a more or less striking white spot. Hands and 

 fingers with large upstanding spines, white in colour, some with 

 darker tips. Fingers slightly gaping, with large black horny 

 tips. 



• Legs of the left side shorter than, but otherwise almost simi- 

 lar to, those of the right. The meropodites have one or two 

 spinules at the infero-external extremities. The carpopodites 

 have each a strong distal spine, and the propodites are only 

 armed with some small denticulations on their lower extremities; 

 that of the hinder left leg is shorter and thicker than the others, 

 and has a distinct, somewhat tubercular ridge separating the 

 upper and outer surfaces. The dactylopodites are usually con- 

 siderably shorter than the preceding joints, and are tipped with 

 a strong black, curved spine ; there are six or seven rather 

 strong spinules in a row along the lower surface. 



Colour. — Legs, chelipeds and other appendages greenish or 

 olive-brown, the dactyli white or yellowish. Carapace lighter, 

 only the anterior angles brownish. Eyes with a white ring just 

 before the cornea. Antennal flagellum blue. All the spines 

 and roughnesses of the chelipeds are white or yellowish, as is the 

 greater part of the fingers. The propodites of the legs have a
