Broteas nigrocinctus of C. Koch (Die Arachn. x. p. 14, 

 fig. 763) ; so that until evidence is forthcoming that these 

 transversely banded forms, which, if conspecific, must be called 

 vtftatus, are the same as what C. Koch described as Broteas 

 honariensis, I think it is wiser to adopt the latter name for 

 the species that Thorell described as vittatus. 



Tiie form rugosus described by Thorell as a variety of this 

 species is, I think, probably a distinct species. 



Bothriuriis coriaceus^ sp. n. 

 (PI. V. %. 12.) 



^ . Colour : carapace blackish, clouded or variegated with 

 ferruginous ; tergites black, with a red stripe along the hinder 

 border ; tail ferruginous above, the lower surface of the seg- 

 ments nigro-lineate, the black lines expanding and fusing 

 behind into a transverse vitta ; palpi ferruginous; legs and 

 ventral surface Havous. 



Allied to B. honan'ensis. 



Upper surface of the trunk finely and closely granular 

 throughout ; the sterna also closely and finely granular 

 throughout, the anterior ones smoother; the stigmata elongately 

 ovate. 



Tail smooth above and below, the lower surface of the first 

 segment obsoletely keeled beneath ; the superior and supero- 

 lateral keels and the space between them granular on the 

 first segment ; the supero-lateral keels obsolete on the third, 

 being merely represented in front and behind by a tubercle ; 

 the superior edges of the fifth smooth or granular only in front. 

 The inferior lateral keels on the fifth are present and denticulate 

 on the posterior two thirds of the segment, and the median 

 keel is almost as long and also denticulate ; between them 

 on each side there is an oblique series of denticles which 

 defines in front the posterior area ; the vesicle is narrow 

 pyriform, not depressed below, but lightly depressed above. 



Palpi as in B. honariensis^ but with tiie manus a little less 

 robust. 



Pectines witli from 15-18 teeth. 



The first pair of feet with a single pair of spurs at the apex, 

 the second with two pairs, the tiiird and fourth with a median 

 pair also. 



Total length up to 48 millim. ; length of carapace 6, of 

 tail 28. 



Loc. Chili. 



The Museum has four examples of this species (3 ^ and 

 1 ?), two being ticketed merely Chili, the others (1 $ and 

 1 ? ) Coquimbo.
