A CONCISE and excellent “Handbook of North China Amphibia and Reptiles” by Dr. Alice M. Boring, C. C. Liu, and S. C. Chou, has been published as a Peking Natural History Bulletin (August 1932).

THE giant nuclei of full-grown oocytes of Amphibia offer unique opportunities for anatomical and physiological study, on account of the relative ease with which they may be isolated and handled.
