Doctor Guenther, as quoted above, in a paper dealing with new 

 additions to the British Museum snake collection, mentions Ophites 

 albofuscus w^ith the statement: ''Occurs also in Formosa; feeds on 

 lizards.' ' In Boulenger's catalogue there is no indication of any speci- 

 men of this species from Formosa being in British Museum. I take it, 

 therefore, that Guenther mistook Swinhoe's specimens from Formosa 

 for this species, a supposition the more probable as he afterwards in 

 describing Ophites septentrionalis referred it to the same genus. 0. 

 albofuscus is restricted to Sumatra and Borneo (see p. 357). 



a Ophites septentrionalis Guenther, Proc. Zool. Soc. London, 1875, p. 233 (type- 

 locality, unknown, but supposed to be "northern India," Boulenger giving "Hima- 

 layas or Khasi Hills (?);" Jerdon, collector). 



From Septentrionalis, signifying northern. 



& For Mr. Ruhstrat, who collected the types in southern Formosa.
