376 THE GENUS PANOPEUS — BENEDICT AND RATHBUN. 



20. Pauopeus berniudensis, sp. nov. 

 (Plate XX, tig. 2; plate xxiv, figa. 14 and 15.) 



Carapace distinctly areolated, posteriorly as well as anteriorly. 

 Areolatious ornameDted with transverse lines and occasional small 

 clusters of granules. 



Front much produced, rather deeply cleft in the center, the cleft 

 rounding out into the median lobes which are produced at this point. 

 Outer angles of the front not produced in some specimens, and slightly 

 in others. Edge of front oblique, thickened, densely granulate, and 

 showing a slight marginal groove. There are two fissures on the uiDper 

 orbital margin. 



First and second teeth of the antero-lateral margin flat and thinj 

 third and fourth thickened, with anterior margins concave and hol- 

 lowed. The sulcus of the coalesced tooth varies greatly with the speci- 

 men. Second tooth the largest, separated from the first by a wide and 

 deep notch ; anterior margin straight, pointing slightly forward and 

 not at all hooked ; posterior angle nearly straight anteriorly, but 

 rounding backward to the broad and deep notch which separates it 

 from the third tooth. In most specimens the anterior margin of the 

 third tooth is concave. The tooth is much narrower than the second, 

 and its posterior margin curves gradually backward to the bottom of 

 the notch. Fourth tooth much the smallest, sharp ])ointed, and di- 

 rected nearly perpendicular to the median line. The depressions 

 between these teeth unite with the depressions between the areolets. 



External hiatus of orbit widely V-shaped. Internal angle of lower 

 margin produced into a rather sharp tooth. Eeraainder of margin not 

 produced in a flattened, rounded tooth, but nearly straight. There is a 

 slight swelling instead of a hepatic tubercle. 



Outline of male abdomen slightly concave. First and third segments 

 comparatively narrow and of about equal width. Second segment 

 much narrower, showing the sternal plates. Coxte of fifth pair of feet 

 not in contact with anchylosed segment. Outline of third normal seg- 

 ment very convex or rounded, of fourth normal very concave, and of 

 fifth normal nearly straight. Penultimate and terminal segments 

 about equal in length. Distal portion of penultimate segment slightly 

 broader than the proximal. 



Meros of chelipeds very deep, having a quadrate appearance, and 

 carrying an obtuse tooth on its upper margin. Carpi, chelipeds, and 

 bases of the dactyls finely granulate. Carpal depression well defined 

 along the margin, and extending around to the tooth on the inner 

 angle. Large cheliped very deep and rather thick. Fingers light 

 brown, in some specimens white. Ambulatory feet slender ; dactyls 

 very slender and hairy. 



The antero-lateral teeth are somewhat like those of areolatus, which, 

 however, is separated from hermiuJensis by other strongly marked char- 

 acters.
