Description of Type Specimen: Ventrals, 189; anal single and 

 entire; caudal scutes, 50 plus, divided (tip of tail missing); dorsal 

 scale rows, 21 anteriorly, 23 on middle of body, and 19 posteriorly 

 (formula therefore 21-23-21-19); upper labials, 8 on left side, 7 on 

 right; lower labials, 9; i preocular, 2 postoculars; temporals 

 somewhat irregular, about 2+3+4, the upper left anterior temporal 

 much reduced; loreal longer than high; nasals injured on each 

 side; anterior chin shields in contact with eiach other and with the 

 first 4 lower labials; posterior chin shields shorter than the anterior 

 and separated from each other by two or three small scales; other 

 head shields normal for the genus. 



Total length (tip of tail missing), about 745 mm.; tail length, 

 112 mm. 



The dentition is as follows: maxillary teeth, 14 on the left side, 

 15 on the right, the last two distinctly enlarged; mandibular teeth, 

 14 on the left side, 13 on the right, decreasing slightly in size; 

 palatine teeth, 13 on the left, 11 on the right; pterygoid teeth, 

 21 on the right side. 



The color pattern (Plate I, Fig. 2) is composed of 24 whitish 

 rings on the body and 6 on the tail. These rings are about one 

 and one-half scales wide on the mid-dorsal line and two scales wide 

 on the first row of scales; on the sides and on the belly, posteriorly, 

 they are mottled with darker. Bordering the whitish rings are 

 black annuli about two scales wide dorsally and one scale wide on 

 the belly. The black rings are separated by red rings, two to three 

 scales in width. The actual colors cannot be determined from so 

 old a specimen, but there are indications that the whitish rings may 

 have been suffused with pink. 



The head is black nearly to the tips of the parietal shields, 

 except for flecks of whitish on the lower portions of some of the 

 upper labials. The chin is whitish except for some black on the 

 first 5 or 6 of the lower labials. The first black ring begins about
