5. Colour: upperside of trunk, upper and under sides of tail, and chelae a tolerably uniform deep brown, 

 without definite pattern of pale markings ; legs and underside of the trunk paler yellowish-brown. 

 Carapace somewhat coarsely granular, with symmetrically arranged smooth or almost smooth paler brown 

 patches, especially on its lateral slopes ; about as long as first and second caudal segments, shorter than 

 the fifth. Terga without definite keels, more coarsely granular posteriorly than anteriorly ; seventh with 

 four strongly granular keels. Sterna smooth, with a few coarse punctures ; the last finely granular at the 

 sides and with one granular keel on each side. Tail about four and a half times as long as carapace, 

 almost parallel-sided ; the inter carinal space at most sparsely and finely granular, all the normal keels 

 well developed and granular except the inferior medians of the first, which are weakly granular ; median 

 lateral keel strong on first, short on second and third segments ; fifth segment with keel reaching the 

 middle of its lateral surface ; superior keels of segments 1-4, and superior lateral keels of segments 2-3, 

 and in a lesser degree of 1, ending in a spine ; second segment a trifle wider than long, third as long 

 as wide, fourth considerably longer than wide, fifth twice as long as wide ; vesicle almost smooth, sub- 

 granular laterally and at base. Chelce : humerus and brachium at most finely granular above, upperside 

 of brachium almost smooth : their surfaces bordered w r ith granular keels ; hand large, its width nearly 



■ 



as great as the length of the underhand, subcristate above and internally and distinctly granular 

 internally; fingers in contact, movable about as long as the carapace and almost twice as long as width 

 of hand ; six teeth along the inner series. Legs with femora and patellae, especially of third and fourth 

 pairs, finely granular. Pectinal teeth 15-17. 



S . Smaller than female, trunk a little more coarsely granular and with tail slightly longer, being about five 

 times as long as the carapace ; third caudal segment as wide as long. Hand more strongly crested than 

 in female, its width almost equal to the length of the underhand, and more than half the length of the 

 movable finger. Pectinal teeth 18-20. 



Measurements in mm. — $ . Total length 45, carapace 5*5, tail 25*5. c? . Total length 34, carapace 4, tail 21.

Hal. Mexico, neighbourhood of the city and Lake Chalco (Mus. Brit. 2 ), Coyoacan, 

 eight miles from Mexico city (Howard Crosbie, in Mus. Brit.). 



Koch and Kraepelin give no exact locality for this species. 



Subsp. dagesi, no v. 



2 . Resembling the typical form, but with only 13 pectinal teeth and distinctly variegated on the trunk, limbs, 

 and tail, the terga being ornamented with four black bands separating five pale bands ; tail patched with 

 black above, laterally, and below, the pigment on the lower side taking the form of spots round the base 

 of the setae ; lower side of last abdominal sternum with six small spots, the other sterna very indistinctly 

 spotted ; similar spots upon the larger setal pores on the chela3 ; hands lined with black, and black at

base of fingers. 



Total length 37 millim. 







Hah. Mexico, Guanajuato, in the mountains (A. Duges). 



Subsp. smithi, nov. 



c? . Resembling the male of the typical form in most characters, but with 22-23 pectinal teeth, variegated in 

 colour much as in V. mexicanus, subsp. dugesi, but not so definitely spotted on the setiferous pores, and 

 with the tail shorter; the carapace as long as caudal segments 1 + 2, and almost as long as 5, the hand 

 narrower, its width less than half the length of the movable finger. 



Measurements in mm. — Total length 30, carapace 4, tail 18.
