Or crustaceans, the only representative, we believe, is & a small 
cray-fish abounding in the filthy, stagnant waters about Quito; 
its name is undetermined. 
In regard to the character of the insect fauna of the Vallo 
we quote from a letter addressed by Andrew Murray, Esq-, lie 
Packard. ‘It is thoroughly Columbian. It would be natur z 
expect that northern types should run down the Andean a a 
high elevations like Quito; but I have not found the effect to : 
much the presence of such types more there than in the pes 
the Columbian district (in which they are very largely intr i 
as I think), as the absence of tropical looking species, whieh ws sith 
lower down in Venezuela, Cayenne, etc. Not t that there PET 
large and gorgeous species, but that the mass seems minute pare also 
and of little brilliancy, but still such genera and forms a . 
met with in Columbia itself.”
