The Inhabitants of the Aquarium 239 



The under side of the carapace is sulphur 

 yellow with a symmetrical design of grayish 

 black blotches, which show frequent irreg- 

 ular yellow lines. Two large spots of a 

 light sulphur yellow on the part connecting 

 carapace and plastron are noticeable and 

 characteristic. The plastron is light orange 

 yellow. The plates are divided by narrow 

 dark seams. The head is rather small and 

 blunt, with conspicuous eyes placed close to 

 the nose. The iris is golden-yellow, di- 

 vided into two equal parts by a broad black 

 line. The neck is short and, like the head, 

 has fine and sharply defined lines of clear 

 yellow. A white spot appears in line with, 

 and a little behind the eyes. The lower 

 side of the legs and all soft parts of the 

 body bear stripes of clear yellow on a gray 

 or blackish background. The upper side of 

 the legs is uniformly grayish black. Very 

 large webbed-feet make this turtle a good 

 and rapid swimmer. The tail is long and 

 strong and mottled and striped with yellow.
