BIBLIOGRAPHY. 



A complete historical bibliography upon all parts of the 

 brain discussed in this article would be too voluminous, hence 

 in some cases a recent article containing a historical summary 

 and bibliography is referred to in preference to older work.

 Zeit. wiss. Zool. XXXIX, 1883, pp. 191-294; 5 pi. In the pineal 

 eye is a white pigment which is not transparent, p. 230.

morphology of the vertebrate ear. Jour. Morph. VI, 1892, pp. 

 1-360; 26 figs. 12 pi. p. 129 shows close relation of 7th and 8th 

 nerves, p. 20, 50 discusses relations of endolymphatic sac.

4. Beard, J. — The parietal eye in fishes, a note. Nature, XXXVI, 



1887, p. 340. In the young larvae of petromyzon the pigment is 

 black, in older larvEe, white, and in the adult, black. The relation- 

 ship of these pigments in the parietal eye is unknown. 



5. Be;raneck, Ed. — Surle nerf parietal et la morphologie du troisieme 



ceil des vert^br^s. Anat. Anz. VII, 1892, pp. 674-689. Thinks that 

 there are three unpaired dorsal structures — paraphysis, parietal eye, 

 and epiphysis — the parietal having a distinct nerve ; the paraphysis 

 appearing later than the other two, arose from the prosencephal. A 

 good historical review.
