Dendrotrochus, Pilsbry, assigned to Trochomorpha
From considerations of shell characters, and perhaps of geographical distribution, Pilsbry attached to the genus Papuina, a compact and newly defined group, Dendrotrochus, embracing the species kindred to (Helix) helicinoides, Hombron and Jacquinot. The author of it added that the soft anatomy of the section was unknown to him.
Some examples of the animal or the type species collected by Dr. V. Gaunson Thorp, of H.M.S. "Penguin," presented by him to Dr. J. C. Cox, and transferred by the latter to the Australian Museum, have just been examined by myself. The result is to convince me that at least T. helicinoides, and probably the species Pilsbry associates with it, must be dismissed from the genus Papuina, and be ranked under the genus Trochomorpha.
