BRACllYU'KA FROM TORRKS STRAITS. 31 



supra-orbital margin is represented as open and V-shaped. The lower orl)ital margin, the 

 tubei'cles on the eye-stalk, the basal joint of the antenna, and the external niaxillipeds 

 are all figured almost exactly as in our specimen. The tirst pair of walking-h^gs are 

 rather stouter. The most marked ditference, however, is that the tubercle on the under- 

 side of the hepatic region is more strongly developed, being represented by a curved 

 transverse ridge, fmni the outer end of wliich a row of granules (not found in our 

 specimen) runs backwards for a short distance pai-aliel to the lateral margin of the 

 carapace.

The lateral margins of the cai-apace are more nearly parallel than in /'. Jukesii. 

 The surface is less uneven, the transverse ridges being less marked, but the regions are 

 fairly prominent and well-defined, though there is some variation in these respects 

 among our siiecimens. The granulation of the surface is much finer and there is a 

 scanty short pubescence interspersed among the granules. The frontal lobes are 

 separated from the upper orbital margin on each side by a shallow concavity. Both the 

 fissures of the upper orbital margin are open and V-shaped, whih; a third, present in 

 some members of the genus, is slightly indicated by a notch at the base of the outer 

 orbital tooth. This tooth is generally more acute than in P. Jnkesii, but the two 

 succeeding teeth on the latex'al margin are less prominent than in that species. The 

 lobes of the lower margin of the orbit are low and rounded, and the edge is finely 

 granulated. There is no tubercle on the sulvhepatic region behind the orbital margin. 

 The basal joint of the antenna bears a slight longitudinal ridge on its ventral face and is 

 produced externally into a broad rounded lobe, flattened dorso-ventrally and projecting 

 into the orbit. The two succeeding joints are robust, the third joint especially being- 

 expanded and compressed. 



The large prominence on the eye-stalk has a peculiar and characteristic form. It is a 

 crescentic or sickle-shaped blade, springing from a narrow base near the distal end of 

 the anterior edge of the eye-stalk, and curving over, close to but free from the corneal 

 surface, terminating externally in an acute point. 



The ischium of the third maxilUpeds is only faintly ridged on its ventral face, and the 

 antero-external process of the merus is very small, not reaching to one-half the length 

 of the carpus. The chelipeds are feeble in both sexes, the palm cylindrical, without 

 ridges, but faintly granular and pubescent. The second and third pairs of walking-legs 

 have the merus pubescent and faintly granulated, but without teeth on the margins. 

 The anterior crest of the carpus has rounded proximal and distal elevatioirs, the latter 

 close to the end of the joint. The propodus is considerably narrower than in L\ Jnkesu,
