DESCR. The head is of moderate development, very much depressed, 

 slender, elongated, pointed towards the snout, which is subconical. The 

 rostral plate is large, depressed, owing to the declivous snout ; very con- 

 vex, almost protruding, though the jaws be even. The nostrils perfo- 

 rate about the middle of a single plate, situated upon the side of the 

 snout. An elongated supra- or internasal, lies almost horizontally over 

 the nasal plate; it is broadest anteriorly, where it is contiguous to the 

 rostral; tapering posteriorly, where it meets the postnasal. The pre- 

 frontal is large, subrhomboid, almost as broad as long, contiguous ante- 

 riorly to the rostral, thus keeping the nasals, as well as the internasals, 

 widely apart. The postfrontals are rather large, sublozenge-shaped, 

 contiguous upon the middle of the snout, thus preventing the vertex 

 plate from coming into contact with the prefrontal. The vertex plate 

 is moderate, elongated, subpentagonal, broadest anteriorly ; its ante- 

 rior angle engaging between the postfrontals. The parietal is unique, 

 broadest posteriorly, slightly notched at the summit to admit the ante- 

 rior and broadest extremity of the middle occipital, which is quite 

 small and spear-shaped. The latero-occipitals are well developed,
