DR. J. ANDERSON ON TIIE REPTILES 



Htdrophis cyanocincta, Daud. 

 7 from the fishing-stakes at Mergui. 



Hydrophis gracilis, Shaw, Gii)ither, I. c. p. 373. — H. Guen- 

 tberi, Murray, I. c. p. 396, pi. xiii. 

 1 from the fishing-stakes at Mergui. 



This species is easily recognized from the other non -imbricate 

 scaled forms with long narrow necks, by its two large temporals 

 along the side of the occipital and by its divided ventrals. The 

 little shields in this specimen number 283, and are strongly tuber- 

 cular. There are twenty-one rows of scales around the neck. 



Hydrophis Jayakari, Boulenger, Ann. Sf Mag. Nat. Hist. 

 ser. 5, vol. xx. (Dec. 1887), p. 408. 

 1 from the fishing-stakes at Mergui. 



This species is allied to H. ornata, Gray, but is quite distinct 

 from it. 



It is an addition to the Hydrophids of the Mergui coast. The 

 single type, in the British Museum, as already stated, was obtained 

 near Muscat, Arabia. 



Hydrophis Hardwickii, Gray. 



13 from the fishing-stakes at Mergui. 



The scales round the neck vary from 27 to 30 ; and the longi- 

 tudinal series from the throat to the vent vary from 135 to 197. 

 Two specimens have two postoculars, and three have two post- 

 oculars on one side and one on the other. Eight rows of the ventral 

 scales, in two of the specimens, are strongly spined, each scale 

 bearing a powerful spine about ^ of an inch in length ; and in three 

 specimens the other body-scales are sharply spined, and the head 

 finely tubercular. All these specimens are males. A female has 

 only feeble tubercles on the ventral scales, while the scales 

 external to them are still less feebly tubercular. They have been 

 compared with the types in the British Museum.
