From the above it appears that females with 21 pairs of pregenital 

 legs may give birth to young with 20 and 21 or with 21 and 22 pairs, 

 and further that the colour of the young may resemble that of the 

 mother or be quite different from it. In each case, however, it will 

 be noticed that the majority of the young had the same number of 

 legs as the mother. 



In a recent paper Bouvier (1900c) states that he found in the col- 

 lections of the London and Hamburg Museums 9 specimens of 

 P. moseleyi, viz., 1 ^ with 22, 2 (1 <? , 1 ? ) with 23, 5 (2 <? , 3 ? ) 

 with 24, and 1 ^ with 25 pairs of legs (the rudimentary legs of the 

 genital segment being included by Bouvier in the counting). 



In the <? with 25 and the 3 ? with 24 pairs of legs the last 

 (genital) pair was rudimentary and without claws, except in one ? 

 in which the left stump was provided with a single claw. These 

 four specimens are doubtless specifically identical with the four Pieter- 

 maritzburg specimens in the South African Museum having the 

 same number of legs and formerly regarded by me as doubtfully 

 new (1899, p. 339). In view of the extraordinary local variations in 

 the number of the legs, which I have observed in other species (see 

 P. leonina, p. 105), I have now no doubt that these forms with 23 to 

 24 pairs of pregenital legs are merely local varieties of P. moseleyi. 



In the two males with 24 pairs of legs, mentioned by Bouvier, 

 the legs of the last (genital) pair were very rudimentary and
