Remarks. — This species is related to Calamaria gervaisii Du- 

 meril and Bibron, but differs from it in coloration and marking, 

 and in having a longer tail with a higher number of subcaudals. 

 The average number of subcaudals for C. gervaisii is about 17 

 for males and 13 for females. In the type of C. siduensis. an 

 adult female, there are 25 subcaudals, nearly double the number 

 for females of C. gervaisii. The length of the tail of the females 

 of C. gervaisii is contained in the total length twenty times; 

 of the males, fourteen times. In C. siduensis the length of the 

 tail is contained in the total length nine and a half times; also, 

 the head is slightly longer, and the second pair of chin shields 

 is longer than in C. gervaisii. 



The type was collected under a log near one of the lakes on 

 the small isolated island Cagayan Sulu, in the southern part 

 of Sulu Sea.
