Length of right palmacross mi(ldlc of outer surface 13.6; greatest height, clista(l to middle,6.(i; greatest thickness, near middle, 5.6 mm. Ijpper mnrgin archc(l>lo~rcr nli~rgin strilight for its distal t.!vo-tl~irrls~ the proximal end c11rx.-ing upward and reaching a little fi~rther b;~ckn.ard than t,he uppermt~rgin. Lengthwise through the middle 2 rows of about 9 large tubercles; above and below these, a row of s~naller tl~bercles ; near lower edgea similar row. A larger tubercle at articultltion with d;~etyl is indieatetl.Upper half of outer surface slightly eoncilve; above this, the blunt uppersurface bends orcr toward the inner sarfacc and has three rows ofirregular tubercles; belol\. these, on tlte inner sorface, a narrow lengtllvisecavity, and frlrther down .i rows of tubercles more or less irregular.The basal cross-sections of the fingers are relatively small and similar,suboval and subtriangular, broader in upper half."The left palm is much worn. Length across lniddlc 13; greatestheight, at distal end, 9.7; greatest thicltness, 6.8 mm. The ornamcntat,iorlso far as it can he ~nailc out: is similar to that of the minor palm."(Rathbun)Remarts-\\'ell-preserrc(1 specimens sho\r hemispherical tubercleson the outer surface of the l~and i~nd conical tubercles OII t,l~e uppersurface. The tips of tllc tubercles arc.barsely granlllate. The fisellfinger, which is finely granul;ltc: is bent (lo~rn~rar(l and is at least onethirdas long as tlle inner lengtl~ of the palm.The specimen (XJSRI 9042) figured by TVeller '(1907, pl. 110, fig.11) is the right palm of the species.li~itil the carapace is foiun(1, the generic and f;imili;rl alfinities ofX' lenolensk cannot be determinc
