In the Proceedings of the U. S. National Museum for 1889, 3G3, Dr. 

 Gilbert raises the question regarding tlie validity of this species as dis- 

 tinct from G. y-cauda. We have reexamined our specimens of each 

 species, and have compared them with specimens of what we regard as 

 G. guaymnsiw collected by Dr. Gilbert. 



It is evident that the two species are very closely related and prob- 

 ably they should be combined. The following differences, however, 

 seem to be constant : 



G. y-cauda has a shorter head, more pointed snout, and larger eye. 

 The pattern of coloration of the two seems about the same, but the 

 white spots or blotches are more pronounced in G. guaymasia', while in 

 G. y-cauda the black spots on the back are more prominent, and there 

 is a series of black spots along the middle of tlie side which does not 

 appear in the other species. 



Putting the differences in tabular form w« have the following:
