Note
Three new species of siphonophore belonging to the calycophoran sub-family Prayinae are described. The individual specimens of these were collected, in the Bahamas region, by the submersible DSRV JOHNSON-SEA-LINK II, using her sophisticated sampling devices. One of the new species has been ascribed to the genus Prayola Carre, 1969. The other two show characters that are intermediate between those found in existing prayine genera and have necessitated the erection of two new genera, Craseoa and Mistoprayina. to encompass them. The morphological characters that are of taxonomic significance in prayine siphonophores are reviewed, and a reclassification of one existing species, Rosacea villafrancae Carre, 1969, is proposed.
