Figs. Sl'T - 330. — Diagrams to illustrate 

 the course of the axial canals and the 

 nerve strands within them in the dorsal 

 cup and the first brachial joints of En- 

 crinus (Fi^. 327, aftfi- Beyrich), Rhizocrinus 

 lofotensis (Fij;. 328, after P. H. Carpenter), 

 Antedon rosaceus (Fig. 329) and Bathy- 

 crinus aldrichianus (Fig. 330, after P. H. 

 Carpenter). In Fig. 327 only the distal ends 

 of the interradial canals are represented. 

 The parts which are transversely streaked 

 run superficially on the inner side of the 

 basal plates.
