in the species above described; they are oblong, vertical, and the 

 hair sockets, with which the tubercles of CalUanassa are commonly 

 provided, are not pointing distad close to the surface of the manus, 

 but are directed more, though not completely, normal to the sur- 

 face. Eight tubercles above the lower margin, the hinder ones very 

 small, the two distalmost long, obliquely placed; an oblong tubercle 

 on base of fixed finger. Near distal end, above articulation of 

 dactylus, a large tubercle, and above it, near the rounded corner, a 

 very small tubercle. 



Carpus (pi. 27, fig. 2) detached, smooth, only partially exposed, 

 much less high than manus, and like it convex in both directions 

 but to a lesser degree. 



Paratype a. — Fingers and distal portion of right manus, inner 

 view (ijl. 27, fig. 3). This is part of a smaller cheliped than the holo- 

 type but has the appearance of being also a major chela. Tlie fingers 

 are very broad, and when closed they meet whiJe their outer margins 

 are strongly arched. The dactylus has a strong blunt, rim separating 

 its two surfaces; the outer surface curves strongly over to the ridge 

 forming really an upper surface, on which there are four large 

 tubercles or sockets, transversely placed at nearly equidistant inter- 

 vals. The inner surface is marked except distally by a blunt longi- 

 tudinal ridge, which bears at its posterior end two tubercles and a 

 granule, and divides the surface into two parts oblique to each other ; 

 both parts are a little concave, the upper one has a longitudinal row 

 of two sockets in its proximal half, the lower one has a row of three 

 smaller sockets stretching along the middle portion. Distal margin 

 of palm where the dactylus is attached, \Qvy oblique; two sockets 

 along this margin and one below the upper margin of the palm not 

 far from the corner. The propodal finger is divided lengthwise by 

 a stronger ridge than that on the dactyl ; a row of three sockets below 

 the ridge, and two above the ridge near together. 



Paratyye h. — Left manus, lower portion lacking. Tuberculation 

 of outer surface similar to that of holotype; supero-proximal angle 

 subrectangular. Inner surface with proximal margin more oblique 

 to upper margin than appears on the outer surface; distal margin 

 oblique as in paratype «, with a line of two sockets ; instead of one in 

 upper distal corner of palm there is a subvertical row of three ; four 

 tubercles on lower distal quarter. 



Paratype c. — Right manus embedded in nodule so that only a part 

 of outer surface is visible and no margin except the proximal one. 



Paratype c?.— Right chela (pi. 27, fig. 4), embedded in a nodule 

 so that the outer surface is visible to a great extent. This specimen 

 resembles those of the type lot in its ornamentation and general ap- 

 pearance except that the upper and lower margins of the manus do
