Head 7i in length of trunk; head and trunk 1^^ in tail; depth 2f in 

 head; snout short, pointed, much projecting; cleft of mouth -1 in head, 

 slightly extending beyond eye. £3-6 yer}" small. Pectoral tin reduced 

 to a slight rudiment; dorsal inserted on top of head, at a point nearer 

 snout than gill opening; dorsal ending not far from tip of tail; end of 

 anal two heads' lengths before tip of tail; teeth small, mostly biserial. 

 Body brownish white, paler below, with 29 jet black rings, about as 

 wide as the interspaces extending on the tins; tip of snout and tip of 

 tail white; rings just as distinct on belly as on back, but with occa- 

 sional irregularities. 



According to Bleeker and Gunther, there is also a variety {fasci- 

 atas) with the interspaces ornamented with ocellate spots, and other 

 varieties are said to differ in the relative length of light and dark 

 rings, the latter occasionall}" not covering the belly. 



East Indies. Our three specimens typical in color, collected by 

 Capt. Alan Owston, at Yaeyama, Ishigaki Islands, southern Riu Kiu. 

 The largest is 16i inches long. 



The close resemblance of this species to Lduranus. semicinctus of the 

 same waters has been often noted. {Coluber^ a spotted snake.)
