DESCR. The head is elongated, of moderate development, depressed, 

 and, when seen from above, ovoid in its outline. The cephalic plates 

 are unequal, polygonal, subtuberculous, or moderately multicarinated. 

 The largest are observed on the occipital region, though the occipital 

 plate, properly so called, is small, acutely subtriangular, with the 

 summit of the triangle directed backwards. The fronto-nasal region 

 exhibits two pairs of plates, nearly equal in size to the ones just alluded 

 to. The interocular plates, of which there are two series, are slightly 

 smaller than the preceding. The supraocular plates are smaller yet ; 

 they constitute two curvilinear, and two longitudinal and parallel series,
