suggested by the experiments of Dr. Chapman* on regenera- 

 tion of the thoracic legs of Liparis dispar, which prove the 

 homology of the larval and imaginal legs. 



The marginal wing-bristles admit of further study (fig. 16). 

 My note on those of Melanippe ftuctuata\ was, I understand, 

 the first publication in England in reference to these. Dr. 

 ChapinanJ has dealt with the same, but I have not yet seen 

 his paper on the subject. Messrs. Furbush and Fernald had 

 previously published observations on these structures in 

 America. They are to be observed at the termination of 

 the nervures, but are not of the nervures, since they occur 

 at the wing-margin between the nervures. Professor Fernald 

 believes they are found on the wings of all Lcpidoptera. The 

 function of the marginal wing-bristle is unknown.
