Microstrongyles of the gemmules (fig. 8) in all sizes up to 49 x 

 7 "85 ^ ; curved, and with surface granular owing to fine spines. 



The main difference between the typical African form and the 

 Burmese variety consists in the former having much larger micro- 

 strongyles (83Xi5'7 m) with larger and coarser spines (fig. 10) ; Mr. 

 Highley's careful camera-lucida drawings show clearly the great 

 difference in this respect. Judging from Prof. Weltner's sections of 

 gemmules, these bodies lack the definite outer shell of smooth 

 macrostrongyles, though this may not improbabh^ be due to the 

 breaking down and removal of this layer. A further difference con- 

 sists in the presence, in the African specimen, of slender, finely 

 spined strongyles (figs. 9, 9a), these being absent in the Burmese 

 form, though perhaps this fact is not of much importance.
