Describes a female with young in vtero shortly before birth. The 
function of the yolk-sack placenta is inferred to be the transmission 
of the secretions of the utricular glands to the embryo, by means of 
the umbilical vessels. The function of the allantois is either respiratory, 
or for the absorption of the fluid secreted in the uterine cavity by the 
utricular glands.
