Euhranchipus gelidus (Hay) 1889. Records from New York, Massachusetts, Indiana, Alaska, and Yukon Territory, Canivda, Usually abundant where it is found. The proc- esses on the somites just in front of the egg sac on the female distinguish this species from all others in the genus. The Hay's ('89) hatched the eggs of this anostracan from dried mud, without freezing, and described development iil stages. The wide range is remarkable for a member of this genus. Fig. 1026. Euhranchipus gelidus. A, side view of head of male; B, side view of posterior portion of female.
