REPORT OF NATIONAL MUSEUM, 1898. 

 Osceola doJiata coceinea ScJileyel. 



While this form graduates on the one side into the Osceola elapsoidea, it 

 approximates, on the other, nearly to the 0. d. conjuncta Jan of Mexico on 

 the other. In fact, it is principally distinguished from the latter by its 

 inferior size.

Scales ill twenty-one or twenty -three longitudinal rows, rather wide 

 and obtuse. Head little distinct. Plates of the head much as in 0. d. 

 doliata, the superciliaries narrow and the frontal wide, and the longi- 

 tudinal line of suture of the occipitals only three-fourths, of the length 

 of the latter plate. The outer borders of the occipitals present two 

 posterior divaricating angles, and one on each side at the end of the 

 first temporal. Upper labials seven, third and fourth entering the orbit ; 

 inferior labials nine, the seventh twice as large as the last two together. 

 Loreal rather small ; temporals, 2-2-3. Gastrosteges, two hundred and 

 nineteen; one entire anal; urosteges, forty-three pairs. 



Measure in ents. — Total length, 423 mm.; tail, 50 mm. 



The color is a delicate red with a black tip upon each scale. The
