1897.] Mb. e. t. pocOCk on ETHiopiAisr spiders. 739 



Sternum subspherical, almost as wide as long ; posterior sigilla 

 submarginal. 



Legs elongate and slendei' ; the anterior with scarcely any 

 spines, the posterior somewhat strongly spined ; tarsi and pro- 

 tarsi of 1st and 2nd somewhat thickly scopulate, the scopulae on 

 protarsi extending to the base, though becoming scanty on that of 

 the 2nd leg; tarsal scopuia of 1st divided by a very faint line of 

 setse, of 2nd distinctly divided, of .3rd and 4th divided by a band 

 as broad as the segment, the scopular hairs being visible at the 

 sides ; protarsal scopulae of 3rd and 4th represented by a few hairs 

 intermixed with setae and spines, scarcely traceable on the 4th. 

 Ungual tufts distinct. Claws armed with a single short series of 

 teeth in their proximal half. 



Spinners with basal segment longer than the others taken 

 together; the apical (? retracted) very much shorter than the 

 second, only about one-fourth of its length. 



This genus, with the ocular area wider than long, the distance 

 between the lateral eyes not or hardly excelhng their long diameter, 

 and with normal mandibles, falls into the section Leptopelmatece of 

 the subfamily BarycJielince of Simon (c/. Hist. Nat. Araignees, i. 

 p. 117); and tested by the generic characters of the group 

 published on p. 126, it is related both to Leptopelma and Psalistops, 

 resembling the latter and differing from the former in having the 

 anterior line of eyes strongly procurved, the posterior median eyes 

 small and about half the size of the posterior laterals ; the four 

 anterior tarsi finely, the four posterior very broadly divided, the 

 apical segment of the mammilla very obtuse and shorter than 

 the second, &c., and, if the membranous border be not considered 

 as clypeus, in haviiig the anterior lateral eyes close to the edge of 

 the clypeus. From both, however, it appears to differ in having 

 but three labial teeth, Simon describing the labium of Leptopelma 

 and, by implication, that of Psalistops, as " inordinate spinidosa in 

 parte apicali." It must be remembered, however, that the apparent 

 differences from Leptopelma presented by the divisional line of setae 

 on the tarsal scopulae may be merely a question of age. Unfortu- 

 nately, since neither of the genera in question are known to me in 

 nature, I can make no further comparison between them and 

 EuhracJiycercus. 



ElTBEAOHTCEBCUS SMITHII, sp. n. (Plate XLII. fig. 3.) 



Colour a uniform ochre-yellow on carapace and limbs ; testa- 

 ceous yellow clouded with black on the upper side of the abdo- 

 men. 



Carapace sparsely and subserially hairy ; as long as the patella 

 and tibia of the 1st and 4th legs and the tibia and protarsus of 

 the 1st leg ; less by about half the length of the tarsus than the 

 protarsus and tarsus of the 4th leg. 



Legs 4, 1, 2, 3 ; the 4th considerably the longest, its patella 

 and tibia about equal to those of the 1st ; 1st leg without spines
