 The Musk Turtle, Stinkpot (Aroiiwcliclis 

 odoratus). In comparing our specimens, 

 collected from different sources, with the 

 descriptions given in several books, consid- 

 ered good authorities on the subject, we find 

 discrepancies in some important points. 

 Without going into a very close comparison 

 we describe the Musk Turtle as we see it 

 before us. The carapace is elliptical, with 

 a faintly scalloped outline. A fairly strong 

 ridge runs along the center from head to 

 tail. The plates on the rear two-thirds of 

 the shell slightly overlap each other. The 

 ground color of the carapace is a dusky 

 yellow. The plates have a narrow black 

 border and blackish stripes radiating from 

 the upper edge towards the lower margin 

 of every plate. The marginal plates are 

 narrow, yellowish and divided by fine black 

 lines. The under margin of the carapace is 

 light yellow on the fore part, and black, with 

 yellow dividing stripes, on the rear half.
