Variety (fig. 10). — Spines all lateral or sublateral, short. There 

 are strongly curved spines with broad bases on the second trunk- 

 segment and pre-anal; stout spines on first trunk and anal. 

 Habitat, Corcovada, Eio de Janeiro. 



Another related form has a pectinate process on the anterior 

 angles of the first trunk-segment, thus closely resembling a variety 

 from Fiji (see 22, Plate xv, fig. 6a). 



Variety (fig. 11). — One long seta on each side near the anterior 

 margin of the trunk. Hooked spines on first and second trunk- 

 segments. Habited, near Buenos Ayres, Argentina. 



Variety (fig. 12). — The chief peculiarity is the possession of 

 stout nipple-shaped processes on the second trunk-segment. 

 Habitat, top of Corcovada, Eio de Janeiro. 



Variety (fig. 13). — Stout curved spines on the first and second 

 trunk-segments, and at ends of transverse dorsal row of small 

 knobs. This is very like an Australasian form (see 21, Plate xvi, 

 fig. oa), but the spines are stouter, and there are differences among 

 the smaller spines. Near New York the form occurs with even 

 stouter spines. Habitat, top of Corcovada, Eio de Janeiro. 



Variety (not figured). — Near a South African form which I 

 have figured (see 23, p. 4, Plate ii, fig. 9). It has the spines on 

 the anterior trunk usually changed into sliort ligulate processes. 

 Habitat, Pata (Tuichi) ; and Eio, Brazil. 



Variety (not figured). — With long set?e, as in the type, but 

 only two on each side, on first and second trunk-segments ; between 

 the setae on each side a shorter stout spine. Habitat, Tanibopato, 

 Peru. 



Va7'iety (not figured). — Nearest to the type. On the anterior 

 trunk three long setae on each side, and a curved seta with bulbose 

 base on the foot. The variety is near an Australian one, which is 

 figured (see 21, Plate v, fig. 10). Habitat, Santa Cruz, Tuichi 

 Valley, Bolivia.
