*This species is viviparous (Lynn and Grant, 1940), not oviparous as reported 
by Gosse (1851). Perhaps Gosse confused an oviparous colubrid for E. 
subflavus. 
**Female L. triangulum remain coiled around their eggs for a brief period 
after oviposition in order to compress them into an adherent mass before 
abandoning them (McCauley, 1945; Green and Pauley, 1987). This may account 
for the considerable number of references (Table VI) suggesting that this 
species broods its eggs. 
*There is an unverified report of viviparity in P. regius (Anonymous, 1941).
