Abstract
IN a communication to Nature some years ago1 I mentioned that the annual concentration of the luminescent swarming forms of O. phosphorea in the channel at the entrance to Departure Bay during the summer and early autumn months could be partly attributed to the set of the currents around the islands in the vicinity. This channel has always been regarded as the classical locality from which these forms could be secured, but no effort to collect any had been made for many years until recently. Interest in them revived two years ago in connexion with work on bio-luminescence; diligent search was made for them in the channel throughout the summer of 1959, but not a single individual was seen. If present, they are easily detected at dusk by their brilliant flashes of light when the sexual products are discharged. Moreover, a dredging run through the channel failed to secure an example of the atokous bottom-living form.
