In my private collections are specimens from Volusia, Lake George, 
Fla. A specimen now living in the reptile house of the Zoological 
Garden of Philadelphia exhibits the following colors. The borders of 
the transverse bars, and the markings on the belly are chestnut red, 
while the ground-color of the latter is cream colored. 
SEMINATRIX PYG£US Cope, gen. nov.— Contia pygæa Cope, Tropi- 
donotus pygeus Boulenger. This species has been referred to the 
water snakes of the genus Tropidonotous (Natrix) by Boulenger (Catal. 
Snakes Brit. Mus. Ed. II, V. 1). An examination of the penial 
structure shows that the reference to the Natricine is correct. The 
other characters differ, however, from those of the genus Natrix, so that 
it appears to be necessary to refer it toa new genus. This I propose 
to call Seminatrix, and give the following definition. Sulcus sperma- 
ticus and hemipenis undivided; no papilla; scales smooth, without 
keel or pits; anal plate divided. 
The only known species S. pygea is found in Florida. According 
to Dr. Loennberg.’ its habits are aquatic. While the epidermal scales 
are smooth, the dermal plates are closely wrinkled and reticulated, a 
character which I have not observed in any other Natricine and which 
may be an additional generic character. 
ZAMENIS STEJNEGERIANUS sp. nov.—This species and the one follow- 
ing belong to a section of the genus not represented in my “ Critical 
Review ” (p. 622), which must be characterized as follows: Superior 
labials eight ; scales in seventeen rows; frontal as wide posteriorly as 
the superciliary at the same point. To this this might be added, loreal 
much longer than deep. 
In the present species the profile is gently convex, and the rostral 
plate is slightly prominent. The frontal plate has straight lateral 
borders and its anterior angles are well. removed from the preocular 
plates. The loreal is twice as long as deep, and its superior posterior 
corner is cut off as a separate plate on both sides, and on one, a third 
loreal is cut off below. The eight superior labials are regular, and 
apparently normal. The parietals are truncate posteriorly, and are 
bounded by three temporals and two small scales externally. Tem- 
porals 2-2-2. Postgenials shorter than pregenials. Gastrosteges 166; 
anal 1-1; urosteges 102. Length 782 mm.; of tail, 229 mm.
