THE GENERA AND Sl'ECIES OF SYMPHYLA. 51 



and looks upwards, tlio apical seta as long* as the longest 

 lateral one. In my opiuiou tliis small specimen belongs, 

 nevertheless, to the same species as the large form described 

 above; but, my material being too scanty for a really complete 

 characterisation of the species, I have preferred to mention 

 the small specimen separately instead of admitting its features 

 in the description itself. 



Locality. — All three specimens have been captured in 

 August, 1894, by Prof. Max Weber in the Cape Colony, the 

 two large specimens at Table Bay and the small one at Con- 

 stantie, near Cape Town. 



Remarks. — This species is rather allied to S. chilensisj 

 the reader is referred to the " llemarks " on that species.

 (and var. figs. 3 a — 3 h). 



Material. — Nine specimens from four localities rather 

 distant from each other, and five of them with the full 

 number of legs. Two other specimens from a fifth locality 

 differ in several features, and they have therefore not been 

 talcen into consideration in the description of the species, but 

 are dealt with under "Variation." 



Head. — Seen fi-om above it is moderately narrow in 

 proportion to the length ; the lateral margin is a little 

 angular or rather flatly rounded ; the long seta is inserted 

 somewhat in front of the posterior cud of the mandible, and 

 is at least as long as the breadth of the basal antennal joint. 

 The central rod is rather long, without visible frontal 

 branches ; posteriorly it is connected with the vertex of a 

 rather large triangle at the hind margin, and the sides of 

 this triangle are oblique rods, which are moderately deve- 

 loped in nearly their whole length. 



Anteunse. — In the adults the number of joints varies 

 from twenty-four to twenty-seven. Some few proximal 

 joints (fig. 2 a) on the inner side with one or two thin setse 

 directed much forward and somewhat longer than those on
