The Leucothoe described by Sars under the name of 

 L. Lilljeborgii, Boeck, is certainly the same as my L. impari- 

 eornis. My description was taken from a mounted and only 

 partially dissected specimen, and thus the recurved process 

 of the last segment of the metasome could not be seen. It 

 appears to me that the characters by which Mr. Stebbing 

 would separate L. incisa, Robertson, from this species are 

 insufficient: the gnathopods, especially those of the first pair 

 show some differences dependent upon age. 



This species has been named at former periods " Leucothoe 

 furina " by Sars, Chevreux, and myself. 



I am also inclined to think that Leucothoe serratipalma 

 Delia Valle, is the same species. The chief difference, and 

 it is a very unimportant one, appears to be that there is a 

 slight serration at the commencement of the palm of the 

 second gnathopods, where the point of the finger impinges on 

 the palm.
