at Gualan, Guatemala, and agree with the type specimen in every 

 essential characteristic and have been designated as topotypes. This 

 is a remarkable series of a very rare species, nine males and three 

 females. 



Two specimens belonging to the California Academy of Science 

 were examined and they also agree perfectly with the type. They 

 were collected at Cuastatoya, Jalapa, Guatemala. 



In Doctor Stejneger's original paper on this species he emphasized 

 its close affinity to the other members of the genus, and stated that 

 the presence of the dewlap was not sufficient ground upon which to 

 erect a new genus. His discovery of Ctenosaura halceri three years 

 later, 1901, has bridged the gap between paleaHs and the other 

 species of the genus and also demonstrated the wisdom of not creat- 

 ing a new genus based upon the dewlap character.
