prominent tubercle above each orbit. Gastric region with four 

 strong ones on bhe median line and two others on either Bide. 

 Cardiac region surmounted by two pairs of small tubercles, 

 between which and a sharp intestinal one is a still smaller pair. 

 A large tubercle in the hollow between the gastric and branchial 

 regions, while many others are present on the hepatic, branchial, 

 and hinder regions of the carapace. Rostral horns a little de- 

 flexed, cylindrical, their length equal to rather more than one- 

 third the rest of the carapace Anterior hepatic (post-orbital) 

 spine directed obliquely forwards, broad distally, followed by a 

 small tubercle; a large infero lateral and one or two postero- 

 lateral hepatic tubercles. 



Antennal flagella stout, a little longer than the rostral horns 

 and wholly visible from above. Antero-external angle of the 

 merus of the maxillipeds forming a broadly rounded lobe. 

 Pterygostomial regions each with a large external tubercle, and 

 there is another in front of each anterior angle of the buccal 

 cavern. 



Anterior segment of the sternum of the male with two raised 

 ridges diverging backwards, ending in small tubercles, and 

 parallel with the margins ; each of the three following segments 

 bears several tubercles. Abdomen with a large median tubercle 

 on each segment, the fifth joint narrowest, the last broadly 

 triangular. 



Arm of the chelipeds with two or three tubercles on the 

 median line above and a compressed distal lobe. Wrist with an 

 obtuse crest on its outer surface. Palm a little swollen, longer 

 than broad, and smooth ; fingers pointed, finely denticulated, 

 slightly gaping posteriorly. All the joints with long, coarse 

 scattered seta). Walking legs long and slender, decreasing in 

 length backwards ; all the joints except the dactyli, are cylin- 

 drical and are provided with stiff" setpe, among which are groups 

 of curled setee on their upper surfaces. The penultimate joints 

 have also numerous long and strong setae on their lower sur- 

 faces. Dactyli long and curved, with a double row of spinules 

 on their inner margins. 



Hob. — Described from a single male specimen, 29 mm. long- 

 including the rostrum, from Dunk Island, near Cairns, Queens- 

 land. It is named after its collector, Mr. E. J. Banfield, to 

 whom the Trustees are indebted for many rarities of both 

 Crustacea and fish.
