wider thau long. Rostral low, broad. Loreal long, narrow. 

 Upper labials seven, sixth largest; third and fourth entering 

 orbit. Lower labials nine, fifth largest. Pregenials much 

 larger than postgenials. Gastrosteges about 200. Urosteges 

 about 50. Anal entire. 



Color above gray. Dorsal spots about four scales long, reach- 

 ing to the third or fourth row of scales from the ventrals. Spots 

 grayish brown with broad black borders. About fifty from 

 head to tip of tail. Alternating with the dorsal spots are black 

 spots with brown centers. These spots are one and one-half to 

 two scales long by four scales wide. They are on the first or 

 second to fifth rows of scales. Alternating with these spots is 

 another series similar in shape and size but entirely black. 

 They are on the margin of the gastrosteges and the continuous 

 rows of scales. Occasionally the two lateral rows become con- 

 f.uent. Posteriorly the belly is maculated with many black 

 spots. The spot on the nape is elongated and reaches to the 

 I'rontal. The center is a triangular spot which touches the tips 

 of the occipitals. A black line from the eye to the angle of the 

 moutli. Tills line forms the lower border of a yellowish band 

 which reaches above the eye. A black or brownish line extends 

 across the base of the prefrontals. Upper labials margined with 

 black. Lower labials yellowish, bordered with black. Chin 

 and throat yellow. 



This snake is very rare in Kansas. I have examined two 

 specimens, one fi'om Douglas and one from Franklin county.
