(Plate LI.) 



Two Tree-Frogs of tlie genus Hyla, obtained by Mr. George 

 Stephen, ot H.M.S. ' Champion,' at Port Hamilton, a small island 

 between the Corean Peninsula aud Japan, have been presented by 

 him to the Society. They prove of great interest, as one belongs to a 

 little-known race of Hyla arborea, viz. the \a.r.japonica (Plate LI. 

 fig. 2) ; and the other to a new species, which J propose to call, iu 

 honour of its discoverer.
