E. Blandingii. The head is of moderate size, triangular, narrow, 

 flattened above ; the snout is somewhat prolonged and rounded in 

 front ; the plates upon the upper surface of the head, as well as 

 those upon the sides are perfectly smooth ; the rostral plate is 

 large, pentagonal, presenting an obtuse angle at its summit ; the 

 nasal plates are of moderate size, triangular, rounded posteriorly ; 

 the supero-nasal are narrow, oblong, in contact with each other; 

 the. inter-nasal plate is larger, presenting the form of a lozenge 

 with its lateral angles truncated, the posterior angle is acute, the 

 anterior obtuse ; it is in contact in front with the two supero-nasal 

 plates, its anterior angle not reaching quite so far as the rostral ; 

 the fronto-nasal are of moderate size, sub-pentagonal, their lateral 

 and inferior margins are in contact with the superior margin of 

 the two frenal plates ; the freno-nasal plate is small, triangular ; 

 the first of the frenal plates is oblong-quadrilateral; the second, 

 which is much the larger of the two, is pentagonal ; the frontal 

 plate is pentagonal, much broader in front, rounded posteriorly; 

 the fronto-parietal are oblong pentagonal, their anterior margins, 

 or those which embrace the posterior margins of the frontal, are the 

 smallest; they are in contact laterally with the two supra-orbitar, 

 and posteriorly with the parietal and inter-parietal plates ; the 

 parietals are large, pentagonal ; the inter-parietal is larger than 

 either of the fronto-parietals, and terminates posteriorly in an ob- 

 tuse point; there are four supra-orbitar and two freno-orbitar 

 plates ; the supra-orbitar are four in number, their exterior mar- 

 gin is bordered by a row of seven small oblong quadrangular 

 plates; immediately behind them is a small rhomboidal plate, the 

 upper half of which is received between the posterior supra-or-
