Note Notes 110 — LETTERS TO MERRETT.

[110] Mr. Verrall assures me that even in the present day it is quite impossible to recognise the species of Diptera described by persons unacquainted with the particular group, and that Browne's remarks would apply to hundreds of species. It is possible that an Ephydra may be meant. This genus of small flies, says Mr. Verrall, abounds in such places as Browne describes, but it is likely that other species were with them.
