224 Annals of the South African Musewm. 
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 Ist gnathopod and 6th 
joint of 2nd gnathopod. 
Length : 16 mm. 
Colour : Brown, peraeon 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, R.M. Lightfoot, K.H.B.) ¢ 6, 
2 2 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 streains ; 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 thoroughly searched for the smaller inverte- 
brates.

Although the following species disagrees with the definition of this 
genus in having the Ist and 2nd gnathopods alike in both sexes, the 
2nd not enlarged, it seems best to widen the definition of the gents 
rather than institute a new one. 
CHILTONIA CAPENSIS 0. Sp. 
(Plate XXVIT. Figs. 38-40.)
