Some time ago Dr. ,]. E. flurnioan. United States consul at the 

 port of Utilla, sent to the National Zoological Park, in AVashington, 

 several specimens of an undescribed species of spinA-tailed Iguana. 

 Two of these died recently, and the adult serves as the type of the 

 following description. 



Utilla is a small island, only 7 miles long, situated off the coast of 

 Honduras, in the Caribbean Sea. It is located within the 100-fathom 

 line surrounding the mainland. 



I take great pleasure in dedicating this new species to Dr. Frank 

 Baker, the distinguished superintendent of the National Zoological 

 Park, it being, so far as I know, the first new species described from 

 specimens having lived in the park. 



CTENOSAURA BAKERI, new species. 



Diagnosis. — A rather large dewlap hanging from the posterior part 

 of the throat; caudal whorls of spines separated by one and two rows 

 of scales; spines of median caudal crest subequal, much larger than 

 the other caudal spines; upper side of tibia with somewhat enlarged 

 keeled scales; dorsal crest high, composed of about 40 spines, not 

 continuous with caudal crest.

 of the genus. From C. palearix it differs chiefiy in the less marked
