I zooid with embryo beneath the retracted tentacles, " Calypso " Collection, CioC. with Antropora minus (see below). Both species have very small zooids, vestigial ovicells, and avicularia whose chambers reach the basal layers of the colony between the zooids. The principal difference between them and A. granulifera is that the avicularian chambers are not in series with the dietellae (see below). Amphiblestrum papillatum, as described by Canu & Bassler (1929 : 104, pi. 7, fig. 8, specimen exam- ined from Stn. 5179, " Albatross", Philippines, ) is not Busk's species. The gymnocyst is elongated, the opesial rim is greatly raised, the ovicells are hyper- stomial, and spines are present.
