they entirely cover the oral region. The inner edge, distal to the 

 suture, bears a close comb-like row of short pinnate hairs or setae 

 (fig. id, h, and fig. id') ; proximal to the sutural notch there is a 

 row of longer and less close simple stiff hairs or setae. The outer 

 margin is stiffened by a marginal rib and bears only a few hairs. 

 The exopod is long, flattened, and widest proximally, slender dis- 

 tally and tipped with hairs. The basal article has a thin foliaceous 

 lobe over the base of the exopod. The fourth or penultimate 

 article is relatively small, flat, thin, about as wide as long; inner 

 edge is curved and bears a row of hairs ; outer edge has an obtuse 

 angle with a cluster of hairs. The last article is small, elliptical, 

 flat, longer than the preceding, with a marginal row of hairs on 

 the inner and distal edges. No spines are present on either article. 



The two large foliaceous, convex articles are held, in life, with 

 the inner edges in contact, thus forming a prominent convex roof 

 or operculum over the oral region; in profile it looks somewhat 

 like a large obtuse nose. 



Legs of the first pair are long and slender, with a small, plain, 

 elongated chela, not much thicker than the carpus ; fingers with 

 many short hairs distally; fingers two-thirds the length of the 

 palm ; the chela is about four-fifths the length of the carpus, which 

 is about two-thirds the length of the merus. 



The legs of the second pair are much larger. The right and 

 left chelae differ somewhat in size but are of the same length. The 

 right one (fig. if), in the example figured, is stouter than the left 

 one; both are flattened. The fingers are about two-thirds the 

 length of the palm; the chela is about twice the length of the 

 carpus, which is about equal to the merus. The ambulatory legs 

 are all flattened and biunguiculate, not particularly elongated. 

 Those of the third and fourth pairs have the dactyl rather moder- 

 ately curved; terminal claws are short, strongly divergent, inner 

 one is shorter and at base thicker ; inner edge of the dactyl has 

 two or three spinules. The propodus is elongated ; the inner edge 

 has a row of about four spines, besides the distal pair ; the carpus 

 is about half as long and has a distal blunt spine (fig. ig). 



The small detached leg, believed to be of the fifth pair (figs, 

 ih, ih'), differs from the preceding in having five spinules on the 

 inner edge of the dactyl, and a distal oblique dense brush of 

 numerous hairs of different lengths, the longest pinnate, and a row 

 of about 10 spines along the inner margin, with a corresponding
