DESCR. This species is one of small size : its body is slender, sub- 

 cylindrical, covered with rather well-developed scales, if compared to 

 those of its congeners. They constitute thirty longitudinal series, a 

 good deal smaller on the sides than on the back and belly ; those of 

 the back being somewhat the largest, especially along the middle line. 

 The two middle preanal scales are a good deal larger than the rest. 

 The upper middle caudal series is quite large and transversely elon- 

 gated, and so is the lower middle series also ; sometimes one double 

 series of ordinary shape intervenes between them. On the sides of 

 the tail, they are nearly equal to those of the back. 



The head is depressed ; the snout narrow and tapering, resembling 

 somewhat that of E. samoensis. The symphyseal plate is larger than 

 the rostral ; the supranasals and postfrontals are kept widely apart 

 by the prefrontal, which is contiguous anteriorly to the rostral, and 

 posteriorly to the vertex plate. The latter is quite elongated, spear- 

 shaped posteriorly. The combined parietals are furthermore united 

 to the middle occipital, forming together a large lozenge. The latero- 

 occipitals are well developed, as usual approximating posteriorly, as do
