DESCRIPTION OF THE SPECIMENS 
AND THE FIGURES. 
The description of each specimen is complete in itself, 
giving its main data, which were obtained from my note- 
books as well as from the specimens and their sections. Their 
numbers correspond with those in my catalogue. 
The measurements of the embryo are as follows: C.R., 
crown-rump or sitting height; C.H., crown-heel or standing 
height; and A./., neck rump or length of the spinal column. 
These specimens, with others which I am collecting, will be 
deposited in the Wistar Institute, where they may be studied 
by investigators interested in teratology.
