At once distinguishable from V. mexicanus in having the four inferior caudal keels

2 . Colour a uniform reddish-brown, not variegated ; legs yellow. Closely allied to V. subcristatus, but, apart 

 from the difference in colour, distinguishable by having the chelae more strongly crested, the posterior 

 surface of the brachium being weakly granular and its inferior crest distinctly crenulate • the hand is 

 also distinctly crested, the crests on its inner surface being granular. Terga visibly tricostate. Upper 

 surface of fifth segment of tail with its superior lateral keels granular ; vesicle granular below and more 

 coarsely punctured than in V. snbcristatus. Pectinal teeth 18-19. 



Measurements in mm. — Total length 63, carapace 7'3, tail 36.

2 . Colour reddish ochre-yellow or reddish-brown ; carapace with black tubercle and irregularly-shaped but 

 sj^mmetrically-arranged black patches and stripes : tergites symmetrically marked, the median keel with 

 a very narrow black stripe which sometimes expands in front and behind, on each side of this and 

 separated from it by a narrow pale stripe there is a triangular black spot, the narrow anterior extremity 

 of which extends forwards and often fuses with the anterior portion of the median stripe ; the lateral 

 portion of the terga with a narrow black edge and a yellow stripe separating it from a large black stripe 

 extending from the anterior to the posterior border, and separated from the before-mentioned submedian 

 triangular spot by a yellow stripe ; this stripe is widened in front, but posteriorly it is narrower than the 

 black patch to the right and left of it ; tail clouded below and laterally with black and ornamented below 

 with four black stripes ; vesicle and upper surface of tail clear reddish-brown ; chela} reddish-brown, 

 scarcely infuscate ; legs with femora, patellae, and tibiae externally marbled with black. Carapace 

 coarsely granular, its frontal area nearly smooth, as long as the first and second caudal segments, slightly 

 shorter than the fifth. Terga coarsely granular, nearly smooth anteriorly. Sterna smooth, the last not 

 keeled, and scarcely granular laterally. Tail more than four times as long as the carapace ; third segment 

 much wider than long, fourth almost as wide as long, fifth nearly twice as long as wide ; the anterior 

 segments granular above and laterally, smooth and symmetrically punctured below ; fourth and fifth also 

 smooth above and laterally ; fourth smooth below and punctured, fifth thickly granular below, with three 

 granular keels ; superior and supero-lateral keels strongly developed, coarsely granular, dentate posteriorly, 

 except the supero-lateral of the fourth ; the inferior median keels obsolete on segments 1-4, the inferior 

 laterals represented by a low, indistinct, smooth ridge ; vesicle smooth, punctured below ; median lateral
