69. MICROPANOPE NITIDA, new species. 

 (Plato XLII, fig. 9.) 



General appearance smooth; frontal lobes rounded; second and fifth 

 lateral teeth reduced; color of pollcx not running had- on hand. 



Carapace broad, convex in both directions; regions very faintly indi- 

 cated; surface minutely granulate or almost smooth, covered with very 

 minute punctte, with here and there a larger one. Front inclined, 

 granulate; edge thin, median sinus V-shaped; lobes sinuous, convex 

 for their inner two-thirds. Orbits with two V-shaped sinuses on the 

 superior margin. Lateral teeth live; the first or orbital small and 

 dentiform, the second low and rounded and connected with the first 

 by a shallow sinus; third and fourth large, Avith arcuate outer and 

 concave inner margins and acute curved tips; fifth very small and 

 postero lateral. The outer suborbital fissure is deep, narrow at the 

 base, with convex sides; the inner tooth is low and blunt. The second 

 segment of the abdomen of the male is wide, and at its outer distal 

 corners leaves exposed a very small piece of the sternum. The third 

 segment has a very broad base with angular corners, reaching the 

 coxa^ of the fifth pair of feet. The penultimate segment is short and 

 widens distally. Terminal segment triangular and blunt. 



Chelipeds strong and unequal, with surfaces finely granulate; upper 

 margin of merus granulate or denticulate. Carpus with a short sharp 

 inner tooth or spine, with a blunt tooth beneath it, and an anterior 

 groove; granules having a tendency to form slight rugfe. Large hand 

 strong, with convex margins; upper surface broad and flattened; in 

 smaller specimens having two blunt crests; fingers bent downward, 

 slightly gaping, with punctate impressed lines; prehensile teeth low. 

 Smaller hand resembling the larger, but about two-thirds as wide. 

 Color of fingers dark brown, the color line on the pollex running 

 obliquely downward from the proximal end of the i>rehensile margin 

 and parallel to the proximal end of the i)alm. Ambulatory legs long
