Of the upper premolars, solid symbols = P3, outline symbols = P4. Of the upper molars, symbols solid on left = M\ on right = M2 and completely solid = M3; outline symbols = M1/2. Measurements in millimetres. Lines join teeth of one individual. B, histograms of log. length x width of upper molars of Lophiotherium siderolithicum (Pictet) and the lectotype of L. robiacense Deperet, from Eclepens-Gare, Creechbarrow and Robiac. Original measurements in millimetres. Propalaeotherium parvulum. The lower molars of two other Egerkingen specimens (Stehlin 1905a: text-fig. 26; pi. 9, fig. 35) are relatively much narrower. The greatest differences in size or length/width proportions of this material occur in the P3_4s and M3s, classically some of the intraspecifically most variable teeth (Gingerich 1974). Thus no convincing separation into two (or more) species can be made on the basis of these scatter diagrams. Until a more detailed synthesis is done of all the material (especially that from Egerkingen), it is best to accept only one species as occurring at any one time. Whether or not.
