COMMANDER BURROWS' interesting letter1 on the palolo worm prompts me to confirm his assumption that this annelid occurs elsewhere than in Fijian and Samoan waters. It exhibits a similar periodic rising at three points off the coast of Ulawa Islands in the Solomons, where its name is 'orku'2, and it has also been observed from southern Espiritu Santo in the New Hebrides3. Specimens which I sent to the British Museum in 1936 from Ulawa were identified by Mr. C. C. A. Munro as Eunice viridis Gray, and this is clearly the same as the Eunice virida of Commander Burrows.
