THE GENERA AND SPECIES OF SYJIi'HYLA. 87 



observed iu any other species of this group, with exception of 

 S. anteunata (see below). 



11. Scolopendrella brevipes, n. sp. PI. 1, figs. 5 a — 5 e. 



Material. — One specimen with the full number of legs, 

 and another with ten pairs. 



Head. — Rather elongate, about one third longer than 

 broad. The central rod interrupted at the middle and 

 without lateral branches, its anterior part slender, and the 

 frontal branches thin. 



Antennas. — They contain in both specimens fourteen 

 joints, but it must be supposed that a higher number will 

 be found in other adult specimens. The set* in the central 

 whorls are naked, slender, and tapering from the base, 

 moderately long on the proximal, and considerably shorter 

 on the distal joints. The secondary whorl begins below 

 outside the middle of tbe antennee, but is not developed 

 above even on the most distal joints ; its seta) are con- 

 siderably shorter than those in the central whorls, but 

 comparatively thick at the base. 



Scuta. — The second scutum (fig. 5 a) with the hind 

 margin between the processes straight, without striped 

 baud; the processes are large, considerably longer than 

 broad, distally much produced with the terminal part very 

 narrow ; they have one seta at the outer margin, two on the 

 basal part oi^ the inner margin, and the distal seta ratlier far 

 from the apex. The distance between the processes one 

 half shorter than their length. The antero-lateral setas are 

 between half as long and one third as long as the processes ; 

 between the antero-lateral and the distal sette four rather 

 short setas are inserted along the lateral margin. The third 

 scutum (fig. 5 a) with the processes considerably smaller than 

 those on the second, about as long as broad, distally some- 

 what produced ; the distance between the processes not fully 

 twice as long as their length ; the setse nearly as on the 

 second scutum.
