Rostral, — in contact with 6 shields of which the 1st infralabials make by far the 

 largest sutures. Internasals, — a pair. Prefrontals, — three, none touching a supralabial. 

 Nasals, — lateral, undivided, touch 3 supralabials normally. Temporals, — one anterior, with 

 two subequal scales behind bordering the parietals. Marginals, — a complete row behind 

 the 2nd infralabial. Infralabials, — four. The 4th largest, and in contact with 3 or more 

 scales behind. Sublinguals, — two well-developed pairs, both in contact. Costals, — 

 imbricate throughout. 



An easy snake to identify. It is the only sea snake in which the frontal touches 7 

 shields, and this is in consequence of the triple prefrontals.
