Pending the publication, in a paper now in preparation, of an account of the Holothuria of the Plymouth district, and an attempt at a revision of the European species of that group, it has appeared advisable to publish the following short note, with the view of removing one of the most prolific of those sources of error with which the literary history of the Holothuria has come to be burdened.

Meteor Trails

Attempts to use the decay of radio signals reflected from individual meteor trails to study the upper atmosphere have revealed a puzzling inconsistency in the signal behavior. An earlier paper pointed out that this inconsistency remained even when the previously postulated sources of error were eliminated. As a result, an irregularly ionized trail model was proposed and shown, by calculation of signal characteristics, to be capable of accounting for the observations. This paper presents results of a new experiment which permitted the determination of the ionization profiles as the meteor trails were formed. The predicted irregularities were found, even for trails which exhibited apparently "ideal" underdense signal characteristics.
