224 Annals of the South African Museum. 



Between these large specimens and the Transvaal specimens (and 

 Cape specimens of the same size as these latter) there is every 

 gradation in the length of the 2nd antennae and number of flagellar 

 joints, and the length of 5th and 6th joints of 1st gnathopod and 6th 

 joint of 2nd gnathopod. 



Length : 16 mm. 



Colour : Brown, peraeou and pleon segments banded transversely 

 with reddish, eyes black ; in spirit all the colour, except that of the 

 eyes, fades to whitish. 



Locality : Widely distributed. In the Cape Peninsula it is to be 

 found abundantly in the damp earth and moss near streams and 

 waterfalls, ranging from near sea-level up to the top of Table 

 Mountain, 3500 feet. Also : Stellenbosch ; Sir Lowry's Pass ; Ceres ; 

 Wellington ; Clanwilliam Division ; Swellendam ; George ; Knysna ; 

 Alexandra Division ; Port St. John's, Pietermaritzburg, Howick, and 

 Durban, Natal. (Dr. W. F. Purcell, E. M. Lightfoot, K.H.B.) $, 

 ? ? and young. 



Methuen records it "from streams," The Woodbush, N. Transvaal, 

 and speaks of it as a " fresh-water" Amphipod. So far as my own 

 experience in the Cape Peninsula and at Stellenbosch goes it does not 

 occur actually in the streams ; I should describe it as truly terrestrial. 



The gaps in the distribution will no doubt be filled up as soon as 

 the Union has been more thoroiighly searched for the smaller inverte- 

 brates.

Although the following species disagi-ees with the definition of this 

 genus in having the 1st and 2nd guathopods alike in both sexes, the 

 2nd not enlarged, it seems best to widen the definition of the genus 

 rather than institute anew one. 



CHILTONIA CAPENSIS u. sp.
