In 1938 Roman Kozlowski published a preliminary account of a collection of dendroid graptolites and allied forms from the Upper Tremadoc of Wysoczki, Poland, upon which he had been working for many years. All of the thirty-eight species listed were new to science, as were twelve of the seventeen genera, for the reception of which he erected three new orders, Tuboidea, Camaroidea, and Stolonoidea, in addition to Nicholson's Dendroidea. Presumably, no long delay in the publication of the full monograph was anticipated; but the names have remained nomina nuda, and the only clues we have at present to the characters of the new orders themselves are slight.
