Indianapolis, I find nineteen eggs, seven of which lie in the left ovary. 
These eggs are quite immature. 
Some alcoholic eggs (U.S. Nat. Mus., No. 17956) of this species from an 
unknown locality furnish some points. They are of the usual elongated 
oval form, an inch and a half long and close to an inch in short diameter. 
The outer covering is thick and tough, and it is furnished with numer- 
ous hard points, as if of deposits of lime salts. Within the egg is a 
young racer 104 inches long and evidently nearly ready to come forth. 
The intromittent organs of this specimen are somewhat flattened, broad 
at the extremity, and with prominent terminal angles. The organ be- 
gins to expand from its base. It is furnished plentifully with spines. 
When the sexes unite, when the eggs are laid, how concealed, and when 
they hatch, are some of the things which we need to learn. 
I have examined a specimen (U. 8. Nat. Mus., No. 17969) of Haldea 
striatula from some point in Arkansas. It is 94 inches long and con- 
tains five eggs, each with a young Haldea in it. Only the hindermost 
egg is in the left oviduct. This is a little over an inch long, but the 
others are only a little more than three-quarters. The short diameter 
of the egg is about a quarter of an inch. The embryos are far from ma- 
ture, being only 23 inches long when extended. They have a consid- 
erable mass of yolk still attached to them. The egg-coverings are 
very thin. This cireumstance causes me to conclude that the young 
are brought forth alive. <A series of sections through the snout of an 
embryo reveals the presence of the usual egg-tooth.
