nence on the third. The feet are much flatter, and the toes longer 

 and more broadly webbed than in P. tectum, and the form of the 

 vertebral plates differs from the type. In coloration and in many 

 other characters, it closely approaches Giinther's description of 

 _P. tentoria, but it is more tumid and the vertebral plates have a 

 different form. 



Plates. Nuchal plate short, trapezohedral, broader behind than 

 in front. First vertebral subquadrangular, very little broader in 

 front than it is behind, the anterior margin convex, posterior slight- 

 ly concave, lateral margins sinuate. Second vertebral almost hexa- 

 gonal, the breadth exceeding the length slightly, the posterior 

 margin straight, thus differing from both typical tectum and tentoria 

 in which it is convex. Third vertebral longer than broad, penta- 

 gonal, pointed behind, the anterior margin nearly straight and 

 equal in length to either of the front lateral margins, or slightly 

 exceeding them. Fourth diamond shape, rather attenuate in front 

 and rounded or subtruncate behind ; iiftli twice as broad as the 

 anterior margins of the two caudals. Caudals rather broader be- 

 hind than in front, in breadth at their posterior margin about equal 

 to their length, they are very little smaller than the nearest mar- 

 ginals, and are separated from each other by a very slight notch. 

 Posterior margin of upper shell very slightly serrated. Sternum flat, 

 slightly bent upwards in front, keeled at the sides ; width between the 

 Inguinal incisions less than half the length. Suture between the 

 gular plates shorter than that between the postgulars. Pectorals 

 longer than the postgulars and not much shorter than the abdominals 

 and prseanals. Suture between the anals longer than their posterior 

 .margins, which meet at an obtuse angle. Jaws finely denticulated, 

 •the upper not emarginate in front. Tail short, shorter than the 

 head. Feet broadly webbed, very flat, front of fore leg down to 

 •the base of the first toe, and hinder part of hind leg nearly covered 

 by broad horny scales, hind margin of fore foot also covered with 

 large scales ; claws of moderate size. 



Coloration. Carapace above brown, anterior and lateral margins 

 of plates a little paler. Sternal plates black, anterior and lateral mar- 

 gins, but not the posterior ones, yellow. Limbs and head dull olive, 

 paler below, the first unspotted, in this differing conspicuously from
