Discussion. 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).

angle a little pectinated. The specimen 



dissected was a female as stated by Gruvel. No caudal appendages could be traced, as 



also stated by Gruvel (1907). Further material is necessary to complete the description 



of internal parts. The description and figures given by Gruvel and Borradaile are 



sufficient to recognize the species.
