Hah. Surinam {Krauss). 



Carapace very much like Tatusia peha ; but there are two series 

 of claw-Kke plates, with free projectmg ends, on the anterior side of 

 the lower part of the hiud legs ; there are five plates in the upper 

 series. The skull is large, and nose much more produced ; the palate 

 keeled on the sides in a line with the zygomatic arch. 



In B. peha (I. e. t. 3. f. 3, 4) the palate is rounded on the sides, 

 without any keel, and the nose shorter and rdore slender. Neither 

 of the four skulls in the British Museum is near as large as the one 

 figured by Dr. Krauss j but some of them have the palate keeled on 

 the sides, more as in his figure of T. Kappleri than as the palate is 

 represented in the one he calls T. peha.
