It leads a more active swim- ming life than Anaspides, and with this habit is correlated the flexure of the body and the greater size of the tail-fan and the scale of the second antenna. The mandible is peculiar in being furnished with a four-jointed biramous palp, while that of Anas- pides is three - jointed and uniramous, and the first thoracic appendage is provided with a setose biting lobe on the ante- penultimate joint, thus more resembling a maxillipede. In other respects it agrees essentially in structure with Anaspides. Fam. 2. Koonungidae. — The sole representative of this family, Koonunga cursor, has been recently described by Mr. 0. A.
