specific objections (§170, y) but they may be inferred to be (a) 

 that it is a posi compound (§§174-191) ; (d) that the German 

 list does not include any terms for the branch-like divisions of 

 the cerebellar "tree." If these branches no longer merit spec- 

 ification, postramus and praerarnus will vanish quietly with the 

 polyonyms from which they were condensed. 



§194. Ternia. — From the context (§170, x) it may be in- 

 ferred that this is objected to upon etymologic grounds. Ter- 

 ma does not, it is true, occur in classic Latin lexicons. But 

 neither does chiasma which is embraced within the German list. 

 The latter is the "new Latin" paronym of /t'y/r/ia, and toina is 

 merely somewhat newer Latin for Tipim. Why should we use 

 the longer Latin termimis for tenna any more than the longer 

 Latin decussatio for chiasmal 



§195. Aulix. — This (§170, /?) is the regular Latin paronym 

 of avXa^ and signifies a furrow. It was proposed by me as a 

 mononym for Reichert's Sulcus Motiroi, not merely as a mono- 

 nym but because its resemblance to aula^ readily recalls the 

 fact that it connects the lateral orifice of the aula (the porta) 

 across the face of the thalamus with the funnel-shaped orifice of 

 the "aqueduct." If, as apparently held by His and Minot, this 

 furrow should prove to be only part of the general boundary 

 line {Sulcus liniitans ventriculorum or Sulcus interzonalis) between 

 the dorsal and ventral zones, then it might not need specifica- 

 tion. But the later observations of Mrs. Gage ('96, «), as stat- 

 ed in my paper ('96, d), cast considerable doubt upon this inter- 

 pretation of the "sulcus Monroi." In any case it must be borne 

 in mind that it extends from the aqueduct to the aula and not to 

 the Rccessus opticus as represented in one published figure. 



§196. Cinibia. — This architectural term, signifying a band, 

 fillet or cincture, was'used by me in 1881 in discussing the very 

 distinct ridge across the crus (cerebri) of the cat before I knew 

 that it had been called Tractus pedunculatis transvcrsus by Gud- 

 den (1880) and still earlier {\%6\) fascio transversa by an Italian
