398 Mr. E,. I. Pocock on Scorpiona 



a few granules and a pair of weakly granular keels. Tail 

 long and slender, nearly five times the length of the carapace, 

 which is shorter than its fifth segment; first segment about a& 

 wide as long, second distinctly longer than wide, fifth nearly 

 three times as long as wide; keels as in V. mexicanus, but 

 the terminal tooth of the superior and supero-laterals not so 

 large, being scarcely noticeably enlarged on the first and 

 fourth segments ; fifth with a strong median lateral crest 

 extending over half the segment ; the intercarinal spaces 

 coriaceous, but almost entirely devoid of granules ; vesicle 

 smooth. 



Chelce witli keels and granules as in mexicanus ; hand very 

 large, keeled, the keels weakly granular, the width almost 

 equal to the length of the hand-back and excelling the width 

 of the first segment of the tail. 



Pectincd teeth 15. 



$ . — Difi'ers from the male in its shorter thicker tail, the 

 inferior keels of which are less well developed, the medians on 

 the first being obsolete and on the second weak and scarcely 

 granular; hand smaller and quite smooth, practically withoufi 

 crests and without granules, shining and punctured ; hand 

 narrower than the fifth caudal segment. 



Measurements in millimetres. — Total length (^J) 58; 

 length of carapace 5'8, tail 36 (width of its fifth segment 3, 

 length 8*8) j width of hand 4*2, length of movable digit 6"5. 

 Total length (?) 43 ; length of carapace 5, tail 24 ; width of

 tail rather coarsely granular, its lateral and inferior surfaces 

 very coarsely granular between the keels ; keels developed 

 and granular, as in V. mexicanus ; vesicle granular below. 

 Tail short and thick, about four times as long as the carapace, 

 which is as long as its fifth segment ; fourth segment almost 

 as wide as long, third much wider than long, fifth about two- 

 thirds as wide as long. 



Chelce as in V. mexicanus, but the hand thicker and the 

 digits shorter, the width of the hand about two thirds the 

 length of the movable digit.
