Abstract
In February 1909 Mr John Thompson, Hull, forwarded to me for identification, along with species of Hydroids, specimens of a “Pedicellina,” which he was unable to identify with any known British form. These specimens proved to be of particular interest; and although a first consignment was dead on arrival in Edinburgh, Mr Thompson was successful in obtaining additional specimens, which, having travelled safely, were kept under observation in a living state for a week, when they were preserved for more detailed examination. Cocaine was found to be the most successful narcotising agent.
