d. Type of OpJiisurus bangJco. Java. From Dr. Bleeker's CoUection. 



e. Type of 0. compar, and probably also of 0. apicalis. Sumatra. 

 /. Type of 0. diepenhorsti. From Dr. Bleeker's CoUection. This 



example is evidently an 0. spadiceus, and ornamented on the 

 back with some irregular whitish blotches. 



The mandibulary teeth of the typical specimen of 0. compar are 

 decidedly one-rowed. Kaup has evidently merely copied Kichard- 

 son, and founded, on his authority, the genus Ccecilophis.
