Fig. 46. — Distira ornata ( x i|). 



I have examined 36 specimens exclusive of those I consider should be absorbed 

 under this title. 



It is, I consider, well marked off from the other species. Thus it is one of the 

 few that have no marginal scales. The only other species that are so d'stinguished 

 are cantoris, gracilis and jerdoni, all of which are too we'l differentiated to be confused. 



One specimen referred by Mr. Boulenger to this species, viz., the one presented 

 by Lord Derby to the British Museum and originally described by Gray ' as a distinct 

 species under the name ocellata, has, I consider, such well marked characters, that I 

 take the same view as Gray, supported by Giinther. I refer to it again under the 

 title H. oce.lata.
