1066 General Notes. | [ December, 
an account of various stages in the development and points in the 
morphology of Limnetis gouldii and Chirocephalus holmani, two 
phyllopodous Crustacea. He also describes Wyocryptus setifer, a 
mud-living cladocerous crustacean. Packard describes (Proc. 
Philos. Soc., xx111, 380) the feet in Cryptozoe, a new genus of 
fossil Phyllocaridan crustacean, allied to Nebalia. The figures are 
too poor to show any detail, but the feet, according to the text, 
are much like those of Nebalia. Nothing had been known of 
the nature of the feet in the fossil forms before.
