None, begins: "Towards the end of 1905, the R.I.M. Survey Ship '' Investigator'' trawled five times in the shallow waters of the northern part of the Persian Gulf. On one of these occasions the trawl was lowered late in the afternoon, so that the process of preserving the specimens had to be carried out in the dusk of the evening. While depositing some of them in formalin, my attention was arrested by a fine display of illumination by one of them,-a certain active Polychaete. Before dropping this worm into the solution, no phosphorescence vvas noticed, but under the stimulus of the irritant, two rows of brilliant points of light, one on either side of the animal's back, became visible, and remained so for several seconds before gradually fading away. These points of light were circular in outline, and about the size of a small pin's head. It was noticed that they were separated by equal intervals, that they appeared less in number than the segments, that they were situated about the bases of the parapodia, and that they were very prominent. The worm was soon identified as probably belonging to the genus Lepidasthenia, and was sent to Dr. Willey, of Colombo, who confirmed it in this genus, pronounced it without hesitation as a new and well-marked species"
