THE CENTRAL NERVOUS SYSTEM OF CHAMELEON VULGARIS work of HUBER and CROSBY ('26, figs. I .to 3) it is evident this bulb is more microsmatic than the paired bulbs of the duck, the chicken, the dove, or the parakeet. The sparrow bulb is unpaired but even it has more cellular differentiation than the ,Chameleon bulb. The fibres of the bulb are unmyelinated and without silver impregnations I am unable to analyze them.The centers of the ventro-median wall such as the nucleus septomedialis ( fig. 2), the nucleus septo-lateralis ( figs. 2, 3), and the nucleus of the diagonal band of BROCA ( fig. 2) are similar to those found in other reptiles, CROSBY ('17, Alligator), CAIRNEY ('26, Sphenodon). Although there is a fair sized anterior commissure it does not have an accompanying nucleus as found in previously described reptiles. Both a nucleus of the anterior pallial commissure ( fig. 3), pim.hiP. and a nucleus of the posterior pallial commissure (figs. 4, 15, 16) were found similar to those found by CAIRNEY ('26, Sphenodon).'Following KAPPERS ('21), I am using the terms paleostriatum, neostriatum, and archistriatum, for I consider that these terms indicate the Fig. I .

This including fig. 12 are all in the transverse plane, and area includes the ventro-lateral small celled area, the stained with hematoxylin ventro-lateral large celled area, and the intermedioand eosin. All of these are from the same animal and lateral area. The paleostriatum is not sharply thick, ~1 1 drawings were limited from the nucleus olfactorius anterior outlined with a Spencer projection apparatus.
