526 SNAKES OF CEYLON. 



The drug recommended is chloride of calcium (Ca Cl 2 )* 

 which should be employed as follows. One grain of 

 Ga Cl 2 to twenty minims of water should be injected 

 deep into the gluteal muscles, and acts like a charm in various 

 haemorrhages. Caution. — The same injection hypodermically 

 causes local gangrene and also considerable pain. This 

 injection might be repeated once, but the fact that an 

 injection of ten grains of the salt set up a terrible femoral 

 thrombosis in one case, shows that the drug intramuscularly 

 must be given with caution. 



Other remedies to which an appeal may be made are 

 adrenalin and pituitary extract, both drugs specially 

 suitable as they reinforce the heart, as well as control 

 haemorrhage. 



The triple alliance then of antivenene, Bayliss' fluid, and 

 Ca Cl 2 are the measures upon which the greatest reliance 

 should be placed. 



Parasites. — (a) Entozoa : Von Linstow has identified a 

 nematode or round worm (Kalicephalus willeyi) from the 

 stomach, and oesophagus of Russell's viper. I have frequently 

 found small nematodes about half an inch long attached to the 

 gastric mucous membrane which may prove to be the same 

 parasite. 



Lepidosis. — Typical — Rostral : As broad as high ; in 

 contact with six shields ; the rostro-nasal sutures longest. 

 Supraoculars : Large ; undivided. Nasals : Large ; entire 

 and peculiar in shape. A vertical pillar-shaped portion forms 

 the anterior boundary of the nostril. This bifurcates above to 

 receive the anterior extremity of a crescentic supranasal 

 shield. The nostril lies between two fissures, one above and 

 the other below, both of which nearly extend to the margin of 

 the shield. Supralabials : Ten to twelve ; 4th largest ; the 

 1st touching the nasal, none touching the eye, being separated 

 by two or three rows of subocular scales. Sublinguals : One
