Efemia>i. 315 



From end of snout to vent 55 millim. ; tail 81) ; fore limb 22 : hind 

 limb 36. 



This species is based on a single specimen from Kelif, East 

 Bokhara, preserved in tlie Petrograd Museum, which may be merely 

 an aberrant E. veJox. More specimens are required to establish the 

 validity of E. hedricujn', Avhieli I regard as extremely doubtful.
