faint grooves indicate the articulations. As shown in Text-fig. 25 A and b, 
the fused coxae (cox.) and trochanters (tr.) are well developed, the fused 
femurs (fem.) on the contrary are shortened and show an anterior protuberance 
(pr.) the significance of which is difficult to explain. The fused tibiae (tib.), 
forming an angle with the foregoing structures, are unequally developed, the

Federated Malay States. Illustrating abnormalities in the structure of gonopods and ventral 
plates as observed in four specimens: (A) gonopods closely approximated, with interspace 
much reduced; (B) gonopods fused in the median line; (C) gonopods fused in the median 
line in another specimen, more highly magnified, to show arrangement of sensory hairs. 
All four specimens had sub-triangular ventral plates of small size and abnormally distant 
from the gonopods. (N. del.) 
tibia of the third leg being reduced, whereas that of the second leg bears a 
terminal segment and claw (cl. 2). This claw is curved outwardly toward 
its reduced thumb (th. 2). The tibia of the third leg terminates in a blunt 
rounded process bearing two spines which represent a reduced claw and 
thumb spine (cl. 3 and th. 3). The fusion of the legs is accompanied by a
