The two specimens dealt with here agree well with the specimen of Scalpellum discoveryi Gruvel, 1906, figured by Borradaile, 1916. His specimen and the one illustrated here (Fig. 2) are of about the same size and must be considered as young specimens. It is of great value to illus- trate specimens of different age for further investigators. Larger specimens of the same species as figured by Gruvel, 1907, are quite different, owing to imperfectly calcified plates on the capitulum. I have found similar differences before (Nilsson- Cantell, 1930) as regards the species Scalpellum convexum. Internal parts are almost totally un- known. Of the mouth parts only palpus and mandible could be traced (Fig. 2). Fig. 2. Scalpellum discoveryi Gruvel, 1906 (St. 170). The palpus is typically conical. The - Pf P-- J^- Mandible ..
