A fresh water crab from Colombia.' The occurrence of respiratory pigments is without reference to phylogenetic relationship. Some chironomid larvae which live in stagnant water contain so much haemoglobin that they have long been known as blood worms; others which dwell in well-aerated wa- ters are quite transparent. It has been said that haemoglobin occurs where there is a dearth of oxygen,—often in aquatic habitats on.
