Mr. Bernard Meyer has pointed out a remarkable physiological 

 peculiarity in this species and G. bivirgatus. The poison glands 

 exceed one-third of the entire length of the animal. Stoliczka 

 thus describes their course, J. A. S., 1870, part II, p. 212: — 

 " They are somewhat more than one-third the length of the body, 

 running along the ventral side and accompanying laterally the 

 alimentary and respiratory canal. Their anterior half is 

 extremely thin, after which they gradually thicken, terminating 

 in front of the heart with club-shaped ends, being here partially 

 surrounded by the parenchyma of the internal organs. There is 

 a perceptible thickening of the muscles to be observed here, and 

 when seen externally, the body is slightly thicker where the 

 poison glands terminate." 



This remarkable peculiarity has only hitherto been noticed in 

 the above species, intestinalis and hivi/rgatus. 



C. bivirgatus, Boie, has not been recorded from Indian limits. 

 It is readily known by its immaculate vermilion head, beUy, 

 and tail.

C. annularis, Giinther. 

 Head and neck black above, with a broad yellow (red ?) cross
