Abstract

The larvae of Oregonia gracilis are described, illustrated and compared with those of other known species of the Oregoniidae. The first zoea of O. gracilis of the present study is somewhat different from that of Hart (1960) especially in having a basis and an endopod of the first maxilliped with 2, 2, 3, 3 and 3, 2, 1, 2, 5 setations, respectively and an endopod of the second maxilliped with 1, 1, 5 setation. It is found the Oregoniidae must be a homogeneous group based on the zoeal morphology. A provisional key for the identification of the known zoeae of the Oregoniidae from the northern Pacific is provided.
