In form and general characters this fish agrees with Lebias, but it lacks 
the ventral fins. The relations existing between Tellia and Lebias are some- 
what similar to those existing between Fundulus and Empetrichthys. The 
affinities of Tellia apoda and Lebias calaritana are such as to suggest a pos- 
sible derivation from the latter.

“ La couleur parait grisitre, mais elle est releve chez plusieurs individus 
de bandes brunes verticales, rappelant celles des Cyprinodon [ Lebias] calaritanus 
et fasciatus.”
