The species placed opposite to each other present similar patterns of coloration. 

 Figs. 3 and 4, Plate III, correspond with Fig. 3, Plate III«, and Fig. 6, Plate III, 

 with Figs. 5 and 6, Plate Ilia. The species inhabit the same regions, more or less 

 exactly, excepting the two Figs. 1. The Elapjs dumerili would have been better re- 

 placed by a variety of the Elaps fidvlus of Mexico, which has the red spaces black 

 bordered ; but a good colored plate was not accessible at the time the drawing was 

 made. All the figures are copied from Jan's " Iconographie Generale des Ophi- 

 diens " ; and the colors of such as I have not at hand for reference ( Ekqjs dumerili, 

 Flaps semipartitus, and Flaps psyche) are derived from the " Erpetologie Generale," 

 and from Jan's "Prodrome." The species of Elaps are poisonous; the others are 

 harmless.
