from the Lower Amazons d:c. 63 



Mus. Nat. Hist, Loudon. Mexico, Vera Cruz, and Cordova. 

 A specimen also from Guatemala in coll. Keyserl. — This 

 type $ is identical with a number of females from 

 Messrs. Salvin and Godman's collection from Guatemala ; 

 one of these, submitted to M. Simon in Oct. 1896, was 

 pronounced by him to be identical with his Cupiennias 

 oculatus, 1891. The name Salei therefore will have 

 priority, and I retain the generic title given to this group 

 by M. Simon for the present. 



1877. Ctenus granadensis, Keys. ^, 16 mm. ; ? , 15 mm. 

 Verhand. z.-b. Ges. Wien, p. 682, t. ii. (viii.) fig. 51. 

 Type in coll. Brit. Mus. Nat. Hist. London. New Gra- 

 nada^ St. Fe de Bogota. — This species belongs to the group 

 of Cteninai to which Simon has given the name Uupi- 

 ennius. It appears to be closely allied to his C. celerrimus] 

 since, however, there are no figures given, and the descrip- 

 tion is inadequate for the purpose, I am unable to settle 

 the point. 



1877. Ctenus hogotensis, Keys. ? , 27 mm. Verhand. z.-b. 

 Ges. Wien, p. 684, t. ii. (viii.) tig. 54. Type in coll. Brit. 

 Mus. Nat. Hist. London. New Granada. — Tliis species 

 does not belong to the CtenintB, but to Lycoctenus^ having 

 three tarsal claws and other Dolomedine characters. 



1880. Ctenus cyclothorax, Bertk. S y ^^ iwm. Mem. Acad. 

 Belg. t. xliii. p. 56, pi. i. fig. 18. Tijuca, Brazil. — Key- 

 serling refers this species to his genus Caloctenus, Bras. 

 Spinn. 1891, p. 143, since tibiaj i. & ii. bear seven pairs of 

 long spines beneath. He says : — " Ctenus cyclothorax, Bert., 

 gehort in die Gattung Calocteiiusy Bertkau considers it = 

 Walckenaer's group Ainbiguce, including C. janeirus ? , 

 and that it is probably the male of C. janeirus, while 

 C. ctnnumoneuSj C. K., is the immature male of it. 



1881. Ctenus argentinus, Holmb. ? , 27 mm. An. Soc. 

 Argent, p. 271. Argentina, Buenos Aires. — The spider, 

 Holmberg remarks, is closely allied to Ctenus hogotensis. 

 Keys., and C. Salhi, Keys. His excellent description 

 shows that it very probably belongs to the same group as 

 Sul^i {hogotensis is a Lycoctenus) , to which Simon gave 

 the name of Cupiennius. Holmberg says : — " Femoribus 

 lateribus dorsoque sordide albo nigroque viperino-macu- 

 latis. Patellaruui tibiarumque minus conspicuis lateribus 

 notatis." This character would prove that it is probably 

 distinct from Sulci, Key s., = oculatus, Sim., but very
