[This snake is called "ngu kon kob" ( = tail-biting snake). The 

 belief is quite general among Siamese that it bites with its tail. One 

 version of the popular belief is that it bites with its head when the 

 moon shines and with its tail on dark nights. One of my assistants 

 assures me a friend was killed by being bitten with the tail of this 

 snake. It is not infrequently seen in the Bangkok roads on rainy 

 aights, coiled tightly with its head concealed in its folds and its tail 

 erect.— H. M. S.]

[75687-89. Under decaying vegetation near water. Color of back 

 varying with the individual, from dark gray to nearly black, below 

 white or pink; neck ring like belly; 75689 was the darkest on back and 

 had the richest pink on under side. A brown worm was extending 

 from vent when this snake was taken. — H. M. S.] The "worm" is a 

 Typhlops Jloweri, now U. S. N. M. No. 76163. 



The specimen from Bandon was collected by Mr. Havmoller. 

 The species is called by the Siamese "ngu seng atit " ( = sun-ray snake) , 

 and even in perservative shows the beautiful glowing iridescence 

 which suggests the name. Regarding the specimen from Raheng, 

 Dr. Hugh M. Smith notes that it is ''reputed to be very poisonous" 

 there.
