Excerpt from Palaeontographica Americana, Vol. 3: 1941-1953 So different have our morphological deductions been from the currentlv ac cepted interpretations of the structures, and the phyletic implications have been of such exceptional interest in view of their bearing upon the theories of relation ship recently proposed l)y Teichert and Kobayashi, that it is felt progress will be best served by the publication of our observations at the present time. These results are far from complete. Adequate material for the study of many of the crucial genera by means of thin sections has been lacking. Doubtless the present findings give only a faint indication of the rich mine of morphological informa tion which awaits a more comprehensive study along similar lines. Particularly important is the investigation of the endoceroids by this method, for it has been found that in many cases opaque sections fail to give any indication of the true structures.
