PICUIPINIMAX, in ornithology, is the name of a species of pigeon in Brazil. It is so very small as scarce to exceed the lark in size. Its head, neck, and wings, are of a pale lead colour, with a black femilunar mark at the extremity of each wing; but its long wing-feathers, which are seen when the wings are expanded in flying, are of a reddish-brown on one side, and blackish on the other, with black ends or tips; the tail is long,
Picumnus, Picus. long, and is variegated with black, white, and brown; the belly is covered with white feathers, every one of which has a brown mark of the shape of a half moon at the end.
PICUMNUS and PILUMNUS, were two deities at Rome, who presided over the auspices required before the celebration of nuptials. Pilumnus was supposed to patronize children, as his name seems in some manner to indicate quod pellat mala infantie. The manuring of land was first invented by Picumnus, from which reason he is called Sterquilinus. Pilumnus is also invoked as the god of bakers and millers, as he is said to have first invented the art of grinding corn.
