new Species of Scorpiomt, 417 



proximally, tiie keel along the inner edge of the upper sur- 

 face coarsely granular throughout, the rest of the keels 

 mostly smooth, though more or less granular proximnUy; 

 intercarinal spaces also almost smooth ; lingers long and 

 slender, the movable considerably exceeding the hand-back 

 and more than twice the width of the han 1, furnislied with 

 8 rows of teeth, and on the inner side of these some scattered 

 larger teeth. 



Legs almost smooth externally ; femora weakly granular, 

 very long, patella of fourth as long as carapace. 



Pectinal teeth 4. 



Measurements in milUmetres. — Total lengtli ^Q ; length of 

 carapace 7-5, tail 30, hand-back 8, movable digit 92 ; 

 width of hand 4'2. 



Loc. The Caves, Selungor in Malacca (//. -V. Ridley). 



Easily recognizable by its long and slender chelas and legs. 

 It is the only species of the genus known to me in which the 

 patella of the fourth leg is as long as the carapace. 



Chcerilus Icevimanus, sp. n. 



Colour a tolerably uniform reddish black, not noticeably 

 variegated ; hands paler than trunk ; variegation of legs 

 indistinct, but more obvious than on the trunk. 



Trunk moderately coarsely granular, interocular area 

 coarsely granular in front, more finely so behind ; tubercle 

 more spherical than is usually the case, its anterior portion 

 not prolonged: terga with lateral granular crests j lateral 

 crests scarcely traceable on the fifth. 



Sterna entirely smooth. 



Tail nearly four times as long as the carapace, which 

 slightly exceeds the length of its first and second segments ; 

 upper surface of segments almost smooth ; the superior and 

 supero-lateral crests weakly granular : lower surface of first 

 segment finely shagreened, not crested ; of second also finely 

 shagreened, with scarcely traceable keels; of third with keels 

 still quite feeble, but weakly granular; of fourth with 

 granular keels ; lateral surface of segments finely granular, 

 the inferior lateral crests distinct and weakly granular on all 

 the segments except the first : vesicle smooth, not globular, 

 elongate, its width a little excelling its height and equalling 

 width of fourth segment. 



Chelce : humerus granular above and in front, its superior 



and anterior keels also granular, smooth elsewhere; brachium 



almost entirely smooth, its upper crest with only a few 



granules, also a few on the lower edge of the anterior surface j
