BMNH Several nectophores and bracts also have been identified from more recent Discovery material from the Atlantic (Table 1). Diagnosis. Nectophores with relatively long median thrust block; with extensive ventro-lateral wings, emarginate on ventral margins. Nectosac a relatively short, narrow tube without any pronounced dorso-ventral undulations; squarely truncate apically. Ratio of over- all length of nectophore to that of nectosac, on average, exceeds Bracts large, robust, distally truncate; with semicircular dorsal ridge connecting tip
