SOME UNDESCRIBED STEPHANID.E IN THE BRITISH MUSEUM. 129 



I have made arrangements for the type-specimens of the 

 various aberrations named and figured in this paper, which are 

 ray property, to be placed in the National Collection when I have 

 no further use for them. 



It is my pleasant duty to acknowledge the valuable assistance 

 which has been afforded me by the Eev. F. D. Morice and Messrs. 

 J. Hartley Durrant and K. South in the preparation of this 

 paper.
