CRUSTACEA NORTH PACIFIC EXPLORING EXPEDITION 73 



breadth, i.oi inches. It agrees well in most characters with ^ilediter- 

 ranean specimens, although we have had no opportunity of com- 

 paring it with an individual of the same age. The chief difference 

 is that in our specimen the feet are thickly covered above with stout 

 clavate setre. The tubercles of the hands are numerous, and rather 

 subspiniform than rounded, although blunt, and the antero-lateral 

 teeth are sharp, spiniform, and not denticulated on their sides.

 103. TRAPEZIA MACULATA' Dana 



Trapezia inariilafa Dana, U. S. Exploring Expedition, Crust., i, 256, pi. 

 XV, fig. 4. 



This species seems to approach T. cymodoce Dana {won Cancer 

 cyuiodocc Herbst) by imperceptible gradations. 



Found on the branches of madrepores taken just below low-water 

 mark at Hilo. Island of Hawaii.

Plate IX. Fig. 5 



Trapezia reticulata .Stimpson, Proc. Acad. Nat. Sci. Phila., x, p. t,~ [35], 

 1858. 



Carapax much broader in the male than in the female. Lateral 

 tooth small and little projecting, but acute. Front sinuous as in T. 

 cymodoce- Chelopoda of moderate size, flattened ; carpus obtuse ; 

 inner margin of meros convex and serrated with five or six teeth, 

 those next the carpus little prominent. Ambulatory feet very 

 sparsely pubescent ; dactylus considerably shorter than the penult 

 joint. This species is of a clear wine-yellow color, with a uniform 

 rather close reticulation in fine crimson lines ; below, the reticulation 

 appears on the body but not on the feet. Eyes black. Fingers pale 

 brown. Dimensions of a male : Length of carapax, 0.3 ; breadth, 

 0.35 inch ; female, length, 0.3 : breadth, 0.37 inch. 



It resembles T. arcolata Dana, but the areolae enclosed by the 

 colored network are much smaller and more numerous ; the lateral 

 teeth are smaller, and the teeth on the inner angle of the meros much 

 less prominent. 



Found on coral drawn up from a depth of one or two fathoms on 

 the west coast of Loo Choo.
