those of the pollex ; the largest tooth of the former lies near its base, of the 
latter near its middle. Inner surface of palm very finely granulated; a 
row of granules near and parallel to the distal end of the palm. 
Ambulatory legs of moderate length and width. Posterior margin of 
merus joints unarmed ; anterior margin with a sharp sub-distal spine. Last 
3 joints furnished with a few stiff bristles and long hairs; dactyli slender, 
nearly as long as propodi. The legs have irregular transverse bands of 
color. 
Dimensions :— Length 7 mm.; fronto-orbital width 9.7 mm.; posterior 
width 8.5 mm.; width of front 5.5 mm. 
Type locality : — Kusaie, Carolines; Feb. 9, 1900: 1¢ (Cat. No. 32,861, 
U.S. N. M.). 
This species most closely resembles Sesarma (Parasesarma) lenzii de Man’ ; 
but our species has the lamina of the arm-joint less projecting distally, the palm 
smoother inside and out, the pectinated ridges not parallel to the proximal 
margin of the palm, and the projections of the upper margin of the movable 
finger of different shape and not obliquely placed.

Niue; Nov. 25, 1899; 1 ¢. 
This species is variable in its proportions. In the ¢ from Niue the length 
is to the width as 1:1.35; in a ¢ from Hilo as1:1.25; while de Man 
(loc. cit.) gives measurements of males, which have a width of 1.31 and 1.34 x 
their length, respectively. 
Abdomen of ¢ from Niue a little narrower than those from Hilo or than 
that figured by de Man (op. cit., fig. 310).
