66 Mr. F, O. P. Cambridge on Cteniform Spiders 



Brazil. — I have set forth above reasons for considering; 

 that there is not sufficient evidence as to the identity of 

 this form. None of the authors who have adopted Perty's 

 name mention that they have seen the original type speci- 

 men, so that one can but conclude that their only evidence 

 is drawn from Perty's description and figures. Tliese, in the 

 case of riifibarhis^ are sufficient neither for generic purposes 

 nor for specific identification. I have very little doubt that 

 the spider figured is one of the three species known to us, 

 characterized by red-haired mandibles and the striped pedi- 

 palpi ; but one cannot be certain on such slender evidence 

 as is offered to us in the fiufures. 



1833. Phoneutria fera, Perty. $ , 34 mm. Del. Anira. 

 Art. iii. p. 197, tab. xxxix. 3. Province of the Rio Negro, 

 Brazil. — The above remarks apply also to a certain extent 

 to this species. The specific identity cannot be determined. 

 1 have little doubt that the figure of the eyes is entirely 

 wrong and that Keyserling was right in his assumption 

 that the two large Cteninte which he called ferua and ruji- 

 barhis were congeneric with Perty's species. There are 

 several species, however, of both forms, either of which 

 might equally well have been Perty's original form ; but 

 no one, not even the " earliest author," has any right to 

 assume that Perty's figure of the eyes is wrong, and to act 

 upon that assumption. H the figure is correct, then Key- 

 serling's/e/v/.9 is not the same as Perty's. 1 have assumed 

 the figure to be correct, and have therefore given to Keyser- 

 ling's yerMs a new name. 



1848. Phoneiitria fera, Perty, C. Kocli. ^ , 29 mm, ; $ , 

 34 mm. Die Arach. xv. p. 60, fig. 1459. Brazil. — 

 Koch's beautiful figure leaves no doubt that he had one or 

 other of the large Cteninai before him, while the figure of 

 the eyes and the red hue of the mandibles in the full figure 

 suggest the form described below as C. Reidyi, though one 

 cannot be certain on this point. 1 have not met with any 

 form in which the patellaj of the legs are distinctly red as 

 he lias de})icted tliem. Whatever this sjiecies may be (and 

 possibly the tyj)e is still in existence), one cannot consider 

 it P. Jeriij Pfrly, nor Ctemis Jerus, Walck., with both of 

 which Koch regards his species as identical. 



1848. rhoneutria rujibarbis^ Vtiiy^ Koch, 'i , 29 mm. Die 

 Arach. xv. p. 63, fig. 1461. Brazil. — Judging from the 

 figure, it seems highly probable that this species is identical
