This species is intermediate between the F. olivacea and F. variegat a,'* 

 and the Gyalopium canuruf m., having the broad rostral of the former in 

 contact with the frontal, and the two internasals of the latter. 



Nostril little longer than broad, concave, its apex more than a right angl^, 

 recurved, the plate concave, contracted at its junction with the frontal. A 

 suture from nostril to intei labial suture ; second labial largely in contact with 

 prefrontal ; eye over third and fourth, fifth triangular, sixth largest, seventh 

 and last smallest ; seven inferior labials, postgeueials rudimental. Orbitals 

 1 2; temporals 1 2; occipitals rounded behind, broad as long; vertical 

 broader than long ; superciliaries longer than broad. Scales broad, in seven- 

 teen rows, the second nearly equal first. Gastrostega 138 ; anal divided ; 

 urostega 37 pairs.
