the superior labial plates only being yellow. On the yellow 

 ground of the inferior surfaces there appear, on the anterior 

 third only of the length, dark shades on the anterior parts of 

 the gastrosteges. These extend and blend so that on the 

 posterior two-thirds of the length in the adult the color 

 may be said to be blackish-brown with yellow spots. This 

 well marked species is nearest to N'atrix rhomhifera, also 

 found in the State. 



The present contribution brings the number of Batrachians 

 and Reptiles recorded as found in the State of Missouri to 

 ninety- three, as follows : — 

 16 Tailed Batrachians. 

 13 Toads and frogs. 

 18 Turtles. 

 7 Lizards. 

 39 Snakes. 

 I do not doubt whatever that this list will in time reach one 

 hundred and over, as there are quite a number of species of 

 this class in northern Arkansas, Indian Territory and Kansas, 

 that will eventually also be found in the State of Missouri.
