The remains of this small Dinosaur were got by Mr. G. S. T.

 Elliot. The collection of bones consists of badly crushed fragments 

 of a skull with the anterior part of the lower jaw fairly well pre- 

 served, some slender birdlike hind-limb bones, and a number of very 

 imperfect vertebrae. The vertebrae seem too large to have belonged 

 to the skull, and there being thus some doubt about the bones being

 and to make them the type. 



As preserved, the lower jaw has the left dentary fairly complete 

 with a considerable portion of the right and the predentary nearly 

 perfect. 



The predentary has its upper surface displayed, which is concave. 

 It is 12 mm. long and the same in width. The outer and anterior 

 edges are sharp and doubtless formed a horny beak. 



The dentary as preserved measures 73 mm. in length, and there
