specimens of Polyzonium germanicum reported by Latzel had 14 or 15 
segments and 12-16 pairs of legs. At Sierra Leone in December 
1893 January 1894 I collected numerous specimens of Siplion- 
otidse (P/iznotus africanus Ck.), a family even more primitive than 
the Polyzoniidae. The smallest of these has 15 segments and 
21 pairs of legs, that is, it has only two terminal apodous seg- 
ments, as in adults. This is further evidence of the proposition that 
Diplopoda originally had numerous segments and legs, even in the 
larval condition, for lulidae and other forms in which the pleurae have 
disappeared always have several apodous segments when immature, 
a series of segments being added at each moult, while the legs for 
them are not supplied until the next 
July 30, 1896.
