The dorsal surface ol the ()blon<j;ata presents tlu' two characteristic divisions, the inlraNcntricular and the \entricular ])ortion. The infravt'iitricular portion is characterized b\ tlu' ap[:)earance of a well- defined clorsomedian septum, on t-itlu'r side of which may be setn the ele\a- tions produced l)\' the libers and nucleus const it ut mti; the cla\a. The usual dorsal paramedian sulcus separates the cla\a from ihe cuiu'us, which latter appears to be the lari^er ol these two surlace elexalions. i-iom this fact it may be inferred that the sensory importance of this area has increased, due.
