This small species is rather commou ou the Pacific coast of tropical 

 America. Its peculiar squamation, rendered more noticeable by the 

 corresponding features of coloration, give it an appearance quite dis- 

 tinct in this genus. In other respects it departs less from the usual 

 type than do E. JlaviguttaUun and R. quadrilmeatum. At present, there- 

 fore, we cannot regard Orthostcechits as a group of higher than subgen- 

 eric value.

EECAPITULATION. 



We have in this review admitted twenty species of Ecemulon as prob- 

 ably valid. We give here a list of the species with an indication of the 

 doubts remaining to be solved in each case. The general distribution of
