From personal observation I can say nothing about this species, as I never visited the district where it is found; but with the fame of the Crispin I have always been familiar, for concerning this Cuckoo the Argentine peasants have a very pretty legend. It is told that two children of a woodcutter, who lived in a lonely spot on the Uruguay, lost themselves in the woods--a little boy named Crispin and his sister. They subsisted on wild fruit, wandering from place to place, and slept at night on a bed of dry grass and leaves. One morning the little girl awoke to discover that her brother had disappeared from her side. She sprung up and ran through the woods to seek for him, but never found him; but day after day continued wandering in the thickets calling "_Crispin, Crispin_," until at length she was changed into a little bird, which still flies through the woods on its never-ending quest, following every stranger that enters them, calling after him "_Crispin, Crispin_," if by chance it should be her lost brother.

This is a widely-spread form of Cuckoo in Central and South America, and reaches the northern territories of the Argentine Republic, having been obtained by Durnford near Tucuman, and by White in Misiones. The whole bird is about 18 inches long, and the tail very long in proportion, about 11 inches. The entire plumage, except the breast and belly, which are grey, is chestnut colour. The beak is very strong, and yellowish green in colour; the irides, ruby-red, the eyelids scarlet.

In Colombia this Cuckoo is said to be called _Pajaro ardilla_ (Squirrel-bird), from its chestnut tint. It seems to feed chiefly, if not altogether, on the ground, and when perched always appears awkward and ill-at-ease. On a branch it sits motionless, until approached, and then creeps away through the leaves and escapes on the opposite side of the tree. This, however, is a habit common to most Cuckoos. Its language is a loud screaming cry, on account of which the Brazilians call it _Alma do gato_, implying that it possesses the soul of a cat. It is a very shy retiring bird, and in this respect is more like a _Coccyzus_ than a _Guira_.
