Vcejovis nigrescenSj sp. n. 



Colour of trunk, limbs, and tail a tolerably uniform brown, 

 tips of fingers reddish. 



Carapace rather coarsely granular, but not closely on the 

 interocular frontal area. 



Terga coarsely but sparsely granular, the granules forming 

 distinct lateral keels. 



Tail thick and longish, more than four times the length of 

 the carapace, second segment broader than long, third as 

 broad as long ; superior and supero-lateral keels granular, 

 posteriorly dentate ; infero-lateral low, but quite smooth, 

 infero-median obsolete, only just traceable; upper surface of 

 segments 1 and 2 granular, of the rest almost entirely smooth ; 

 keels of fifth segment only crenulate, its lateral surface very 

 weakly and obsoletely granular above, the median keel repre- 

 sented merely by a low ridge ; vesicle punctured, also weakly 

 granular. 



Chelce : humerus weakly granular above and below, coarsely 

 granular in front, furnished with four strong granular crests; 

 brachium also furnished with four strong granular crests, with 

 a row of strong granules on its anterior surface ; hand costate, 

 the finger-keels distinct and smooth, the three inner crests 

 strong and strongly granular; fingers long, the movable 

 longer than the carapace and longer than the fifth caudal 

 segment, at least twice the length of the hand-back. 



Legs externally granular. 



Sterna smooth, the last with a distinct crest and a few 

 granules on each side. 



Pectines short, teeth 18-19. 



Measurements in millimetres. — Total length 58 ; length of 

 carapace 7, of tail 34, of hand-back 4, of movable digit 8*8. 



Log. Mexico (54. 76). 



Vcejovis subcristatus, sp. n. 



J' . — Colour reddish yellow ; ocular tubercle black ; tergites 

 with a V-shaped black patch and a badly defined submarginal 

 black spot ; tail nigro-lineate beneath. 



Carapace somewhat coarsely granular ; terga also furnished 

 with coarse granules ; sterna smooth, the last with a smooth 

 crest on each side. Tail long, at least five times the length of 

 the carapace, which is shorter than the fifth segment ; the 

 inferior and infero-lateral keels of segments 1 to 4 visible as 

 distinct smooth punctured ridges, the laterals at most very 

 slightly crenulate on segments 3 to 4 ; lateral keel of fifth
