Annals of the Transvaal Museum 
His classification is founded on : 
(a) The presence or absence of eyes. 
(b) The nature of the stigmata. 
(c) The division or non-division of the tarsals. 
( d ) The presence or absence of longitudinal grooves (sulci) on the scuta 
and terga. 
It is on this classification that the Chilopoda from the Transvaal Museum, 
Pretoria, and the Albany Museum, Grahamstown, placed at my disposal, have 
been specially determined. No members of the Cryptopinae have thus far 
been found in South Africa. 
The principal literature consulted was : 
Kraepelin’s “Revision der Scolopendriden ” from Mitteilungen aus dem 
Naturhistorischen Museum, vol. xx. 1903 (2 Beiheft zum Jahrbuch 
der Hamburgischen Wissenschaftlichen Anstalten, xx.); 
and for original descriptions of species : 
Myriopoda Africae Australis, in Museo Regio Holmiensi asservata, recensuit 
i8yi , by C. O. von Porath. 
The Scolopendridae are divided into the three sub-families Cryptopinae, 
Otostigminae and Scolopendrinae. 
The following is a key to the Otostigminae and Scolopendrinae , the two 
sub-families represented in South Africa. 
A. Four eyes on each side of the head. The tibia of the walking legs fol- 
lowed by a proximal and distal tarsus; these form an angle at the 
point of contact. The tibia of the walking legs (except the first) are 
not provided with spines or spurs on the under surface, and they 
have no spine on the distal extremity 
a 1. Opening of stigmata rounded, oval or nearly circular, shallow or sunken 
into body- wall, placed obliquely to the longitudinal axis of body, and 
almost perpendicular to axis in the posterior somites ; on contraction 
it closes antero -posteriorly. Head-plate does not extend over the 
first tergite; basal pj^tes an d longitudinal sulci absent . Otostigminae 
a 2 . Opening of stigmata acute-angled anteriorly, from short triangle-shaped 
to long trianguliform or narrow, slit-like placed parallel to the longi- 
tudinal axis of the body, and contracts dorso-ventrally. Tarsal spurs 
absent or only represented by single spines. Head-plate often ex- 
tends over anterior margin of first tergite or provided with basal 
plates and two median sulci ..... Scolopendrinae 
Sub-family OTOSTIGMINAE. 
Key to the South African genera 
(adapted and slightly modified from Kraepelin’s Revision der Scolopendriden ). 
1. Only nine stigmata developed (seventh segment without stigmata). 
Only first to second seldom first to third segments of antennae naked 2 
Ten stigmata developed (eighth segment without stigmata). Always 
first three or first four segments of antennae naked ... 3 
2. Anal legs have the normal shape, provided with terminal claws. The 
tergites are seldom carinated and coarsely punctured 
Otostigmus Porath (not represented in S. Africa) 
Anal legs have the last three segments (tibia, proximal and distal tar- 
sals) laterally compressed to form a wide oar-shaped or racket-shaped 
plate (see fig. 2 ) without terminal claws. Tergites always carinated, 
and generally coarsely punctured .... Alipes Imhoff
