* Huxley's Sphjeronectidfe seem hardly distinct distinct genus, judging from the drawings of Quoy 



from the Prayidae. Praya dubia is closely allied to and Gaimard, or rather, it is the type of the genus 



it, more so than to the other species of the genus Praya, and if generically distinct from the others, 



thus far described ; it may, however, constitute a these will require a new generic name.
