It leads a more active swim- ming life than Anaspides, and with this habit is correlatinl the 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 tli;it of Anas- pides is three-jointed and uniramous, and the first thoracic appendage is provided with a setose biting lobe on tlie ante- penidtimate joint, thus more reseml)ling a maxilli]>ede. In otlicr respects it agi'ces essentially in structure with Anaspides. Fam. 2. Koonungidae. â The sole representative of this family, Koomniga. cursor, has been recently described l)y Mr. 0. A.
