described the egg-tooth. In one female, taken near Indianapohs, I find 

 nineteen egge, seven of which Ue 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 numerous 

 hard points, as if of deposits of lime salts. Within the egg is a young racer 

 lOo inches long and evidently nearly ready to come forth. The intromit- 

 tent organs of this specimen are somewhat flattened, broad at the extremity, 

 and with prominent terminal angles. The organ begins 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. S. Nat. Mus., No. 17969) of Haldea stria- 

 tula from some point in Arkansas. It is 92 inches long and contains five 

 eggs, each with a young Haldea in it. Only the hinder most 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 mature, being only 24 

 inches long when extended. They have a considerable mass of yolk still 

 attached to them. The egg-coverings are very thin. This circumstance 

 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 

 ogg- tooth. 



Some observations on the tui!tles of the (iems malaclkmys. By O. P. 

 Hay. 

 Of the turtles belonging to the genus Malarlevu/s there are now recog- 

 nized five species, two new ones having been described within recent years 

 by Dr. G. Baur. The genus is a very distinct one, and is distinguished 

 from Chrysemi/s especially by the extremely broad and flat crushing surfaces 

 of both upper and lower jaws. As a result of the provision made for the 

 support of these wide, horny, masticatory plates, the internal nares are 

 thrown far back, so as to lie behind the level of the eyes. In the Catalogue
