than the diameter of the small eye. The median keel on the 

 tergites rather weak, but the four granular keels on the last 

 tergite strong. 



Sfernites smooth, impressed with large punctures; the last 

 with four granular keels. 



2\il constructed as in the preceding species, but rather 

 stronger, being more than three times the length of the cara- 

 pace, which is shorter than the first three segments by about 

 one third of the third segment, and the second segment is 

 wider than long, and the third as wide as long. 



Palpi almost as in the preceding species, but with the keels 

 weaker and not so strongly granular, while the intercarinal 

 spaces also are less strongly granular ; there are thirteen 

 pores on the lower surface of the brachium ; the length of the 

 hand-back considerably exceeds that of the carapace and of 

 the movable digit, these two being equal — it equals, in fact, 

 the first three caudal segments ; the digits are rather short, 

 distinctly lobate and sinuate in their proximal half, the height 

 of the immovable at the base being about one third of its 

 length. 



Legs externally granular. 



Pectines large, with distinct fulcra and 9 teeth. 



Total length 55 millim., of carapace 8, of tail 27 ; width of 

 brachium 3, of hand 5 j length of hand-back 9, of movable 

 digit 7.

This species, with its slender hands, strongly crested 

 superior caudal keels, &c., belongs to the same category as 

 S. inojitanus^ Karsch, anihrachius, Simon, Lindstroemii and 

 lugubris, Thorell, and longimanus, sp. n. It differs from 

 montanus at least in having the carapace shorter than the 

 anterior three caudal segments and in having the carapace 

 considerably shorter than the hand-back. From anthracinus 

 it may be recognized by having thirteen instead of nineteen 

 pores on the brachium, from Lindstroemii and luguhris by 

 having thirteen instead of fifteen pores, and from longimanus 

 by having thirteen instead of ten pores, &c. 



Anueoctonus, gen. nov. (PI. XIV. figs. 14 and 15.) 



Allied to Uroctonus, Thorell, but differing at least in having 

 a single tooth instead of a series of teeth on the lower edge 

 of the movable digit of the chelicerce. 



Type Anuroctonus phcBodactylus (Wood). 



Of this species I have seen a single specimen (female, with
