lin. mich, inferior are clear. The two „Nebenschenkel" on the right 

 and on the left are not so clearly to be seen, and in such a way 

 that the „obere JSTebenschenkel" on the right and on the left are 

 almost entirely wanting, while the „untere Nebenschenkel" on the 

 right and on the left are very clear and protrude as sharp crests. 

 The latter two are about perpendicular on the two „Hauptschenkel" of 

 the lin. nuch. inf. The impressions of the muse, obliquus capitis sup., 

 the m. rectus capit. post, minor and major are very clearly to be seen. 



Between the impressions of the m. obliq. sup. and the m. rect. 

 cap. post, minor and major runs the steep crest of the strong „unterer 

 Nebenschenkel". Between the impressions of the m. r. c. p. maj. and 

 minor we find only a faint vault. There are only traces to be seen 

 of the processus retromastoideus (Waldeyer 2) at the point where 

 the lin. nuch. sup, reaches the 1. n. inf. (its „obere Nebenschenkel"); 

 it is a little better on the right than on the left. 



Especially the impressions of the m. r. c. p. minor on the right 

 and on the left are very rough and full of little crests and openings. 

 The impressions of the m. r. c. p. major and of the ra. obliq. sup. are 

 much smoother. At the point where the lin. nuch. inf. divides itself 

 in the two „Nebenschenkeln" a clear torus is to be seen on the 

 right and on the left (see fig. 2#). This torus is in no way connected 

 with the proc. retromastoideus (see fig. 2 o). The distance between 

 this torus and the proc. retromast. or rather its indication, is 2 cm. 

 on the right and a little less on the left. This torus has also been 

 described by Michelsson (Anat. Auz, 39« Bd., Nr. 23/24, pg. 668). 

 He says there: „Ferner kann auch an de? Teilungsstelle der lin. nuch. 

 inf. in ihre beiden Schenkel ein Höcker vorkommen, wie ihn Waldeyer 

 selbst beschrieben hat (1. c. p. 28 schädel 11) und ausdrücklich vom 

 proc. retromastoid. unterscheidet. Diesen Höcker (man könnte ihn 

 Tuberculum crurium nennen) habe ich an drei Schädeln der Dorpater 

 Sammlung gefunden." ÄIichelsson found these 3 cases on 583 skulls, 

 among which were also 8 specimens of a proc. retromast. We can 

 of course adopt the name Tuberculum crurium and the skull mentioned 

 here, also has this Tuberculum clearly developed on the right and on 

 the left. But yet we must not forget that "Waldeyer means an 

 other tuberculum than Michelsson supposes. 



Michelsson's quotation of ,,Schädel 11, pg. 28" from Waldeyer's 

 book has been misunderstood by him. Waldeyee means on pg. 28, 

 skull 11, a tuberculum, conformable to x in the sketch fig. 2.
