 a tlaw-tuft, the claws bearing no denticle ; very slightly clothed 

 beneath with scattered scopuliform hairs. Protarsi i. and ii. with 

 slight seopula at apex and two stout spines, one apical, the other 

 basal, beneath ; iii. and iv. with numerous spines. Tibia i. bearing 

 at its apex on the inner side, beneath, a pair of stout curved spines 

 set in juxtaposition to each other, with five ordinary spines, 

 2—1 — 3 beneath, and one on the inner side. Tibia iii. and iv. 

 with numerous spines. Femora of all four pairs with five or six 



Pedipalp. Pemur with a few spines at apex above. Tibia 

 fringed on either side beneath with long hair, and six spines on 

 the inner side, two on the outer. Tarsus short, half the length of 

 tibia. Bulb short, pyril'orm, transverse, its stylum very short, 

 curved, directed outwards and backwards.

 5-5 lat. Abd. 5-5 long., 3-5 lat. Ceph. area 4 long. Stern. 3-25

 mam. long. 3'5 ; artl. 1'5 — 1 — -5. Antr. mam. '75. 



My attention was called to a fine specimen, an adult male, of 

 this species by IMr. B. E. Austen when collecting in the neighbour- 

 hood of Manaos, Amazonas, in February 1896, and I have great 

 pleasure in connecting his name with the species. The generic 

 cliaractors which distinguish Jlomceoplucis from Barychelus are 

 well marked. Cephalic fovea procurved ; rastelluui at apox of 

 mandible consisting of five separate teeth ; coxa of pedipalp armed 

 near the base with ouly a few (3-4) small cusps ; ocular tumulus 

 narrower in front. 



M. Simon apparently does not know the male of the species he 

 has made the type of his genus, so that no mention is made of the 

 spines at the apex of the tibiae of the first pair of legs. 



Species described. — H. pentodon, Sim. op. cit. p. 275. 



It is possible that the Spider described above may be the male 

 of the one described by Simon ; but it is not easy to identify a 

 specimen of this sex from a description of the female. He says of 

 it — " Parte cephalica vittis duabus ; " of .//. austeni one would 

 rather say — " Parte cephalica lineis tribus ; " and again he says : 

 " parte thoracica lineis radiantibus, lineaque marginali obscnriori- 

 bus notatis " ; whereas in my specimen there are no radiating lines 

 and no marginal dark line.
