On page 42, instead of Raia cooperi, read:

On page 43, instead of Eaia binoculata, read: 

 56. K. inoriiata .Ionian & Gilbert. 



For the synonymy given on page 44 substitute the following: 

 (Raia inornala Jor. & Gilb. Proc. U. S. Nat. Mus. 1880, 457 and 1881, 74.) 

 Var. inn-mi* is also described in loc. cit. 1881, 74.
