closely allied to Getnzi, Sim. He adds, " Abdomine . . . . 

 duabus maculis punctiformis, ventre qnataor lineis pallida 

 rufesceiitibus prope basin nascentibus, mamillasque versus 

 convergentibus signato." These characters ought to help 

 an identification, except that it is not easy to see what is 

 meant by "duabus maculis," whether two only,. or two on 

 either side; if the latter, it shares this character with SaJh'. 

 Holmberg also remarks that tibiae i. and ii. possess 2, 2, 2, 2, 

 metatarsi i. with 2, 2, 3, metatarsi ii. with 2, 2, 1, 2 

 spines beneath ; also "mandibularum rima (aut canali) cum 

 crista externa, seu postica, 4-dentata." Thus showing 

 clearly its affinities to Cupiennius. 



1881. Ctenus rubn'pesj Keys. ? , 28 mm. Verhand. z.-b. 

 Ges. Wien, p. 577, pi. xvi. fig. 23. Type in coll. Dr. Koch, 

 Klirnberg. Central America, Panama. — Since, according 

 to Keyserling, this species has four pairs of spines under 

 the anterior tibiae and also two lateral ones (in the female 

 sex), it is not improbable that it belongs to Cupiennius, 

 close to C. granadensisj Keys. The type is not in the 

 Museum.

 p. 144, t. iv. fig. 98. Type in coll. Brit. ;Mus. Nat. Hist. 

 London. Rio Grande do Sul {Dr. v. Ihering). — This form 

 is very closely allied to C. boliviensis, sp. n., described below, 

 as well as to C. Keyserlingii. The external plate of the 

 vulva is, however, shorter in proportion to the breadth than 

 in either of the two latter species {cf. PI. III. fig. ii. d, 

 below).

 p. 145. Type in coll. Brit. Mus. Nat. Hist. London. Rio 

 de Janeiro {Dr. Gbldi). — 1 need not here repeat my reasons 

 for changing the name of this species to C. Keyserlingii 

 {cf. sub r/io)ieutria /era, Perty, above). 1 may add, 

 liowever, that it is very unlikely that a species found at Rio
