It is possible that Bate's species may be the male of that 

 to which it is here with doubt referred (see Norman, Ann. & 

 Mag. Nat. Hist. ser. 7, vol. v. 1900, p. 144), or it may be 

 the next species, Socarnes erythrophthalmus. Mr. Walker 

 has examined the type in the British Museum, and finds that 

 thetelson, instead of being as described by Bate " simple and 

 squamose," is really " cleft to the base, without lateral 



* Mr. Walker suggests (Ann. & Mag. Nat. Hist. ser. 6, vol. 5x. (1892) 

 p. lo(>) that while Bate's figures d,ff,h, i are taken from a Lysianax, the 

 entire figure and the tail-piece represent Orchomenc humilis, Costa.
