EOLIS EXIGUA. 



whiteness and opacity of the ova, were more conspicuous than the animals themselves. A 

 few specimens of Holts despecta were found accompanying them. These were readily 

 distinguished by their waved dorsal line. 



Eolis exigua is active in its habits, and, when kept in a glass of sea-water, is fond of 

 swimming on the surface. It is the Tergipes lacinulatus of Loven's ' Index,' but we do not 

 agree with the learned author in referring it to the Limax tergipes of Forskal (Boris lacinulatus, 

 Gmel.), which species, as far as we can judge from the imperfect description and very rude 

 figures, is more likely to be the Tergipes dullifer, Lov., a view which we believe M. Loven is 

 now inclined to take. We think, however, that it would be better to give up the attempt to 

 identify the lost species of early naturalists when they are so imperfectly described as to allow 

 only of a probable conjecture.
