OROCODILIA. 
Dr. J. E. Graves memoir on recent Crocodiles, read before 
the Zoological Society in 1862, is published in Trans. Zool. Soc. 
vi. pp. 125-169. Without entering into detailed descriptions, 
the author gives those of his observations which appeared to 
contribute to a better knowledge of the species, the materials 
examined amounting to more than two hundred examples. He 
draws attention to the very great change that takes place in the 
shape and proportions of the head of the animal in the different 
stages of its growth. The changes seem nearly similar in all 
the species, and may be divided into three stages, viz. those of 
the young, nearly full-grown, and the adult or aged specimens. 
The head and snout of the young are geuerally depressed, with 
more or less distinctly marked symmetrical ridges and depres- 
sions ; and these characters are gradually modified until the ani- 
mal attains nearly its full size, the skull becoming thicker and 
more solid, but yet retaining most of the characters that dis- 
tinguish its young state. After this period, as the animal in- 
creases in age, the skull becomes more and more convex, swollen, 
and heavy, assuming a very different external form. We need 
not enumerate the single species, as the author treats of all the
