SiLYBURA BEDDOMii. (Plate XVII. fig. F.) 



Silybura beddomii, Gunth. Ann. ^ Mag. Nat. Hist. 1862, January, p. 56. 



Snout pointed ; rostral shield compressed into a slight keel above, longer than the vertical. 

 Caudal disk rather convex, not well defined, nearly as long as the tail, with two or three 

 strong keels on each scale. Scales of the middle of the body in seventeen rows ; ventral 

 shields 178; from five to six pairs of subcaudals. The cu'cumference of the thickest part 

 of the body is one-eleventh of the total length. Brown : each scale on the sides with a pair 

 of whitish dots ; each ventral shield with a small whitish spot. A yellowish line along the 

 side of the neck, commencing behind the angle of the mouth ; vent and tip of the tail yellow. 



This species was discovered by Captain R. H. Beddome in the Anamallay Hills and in the 

 Nilgherries, at elevations of from 3000 to 4500 feet ; the specimens are 11 inches long. 



Two views of the head are given on Plate XVII., of its natural size. 



SiLYBUEA OCELLATA. (Plate XVII. figs. E, E'.) 



Silybura ocellata, Beddome, Proc. Zool. Soc. 1863, p. 226. 



Snout pointed ; rostral shield slightly compressed above, much shorter than the vertical. 

 Caudal disk rather convex, twice as long as broad, not very clearly defined ; each scale of the 

 disk with three or four strong keels. Scales of the middle of the body in seventeen rows ; 

 ventral shields 199-203 ; subcaudals from eight to ten, in pairs or entire. The cuxumference 

 of the thickest part of the body is one-twelfth of the total length. Ground-colour of the male 

 yellowish olive, darker towards head and tail ; of the female dull brownish ; of the young 

 dark purplish brown : all with numerous, closely-set, rather irregular transverse series of 

 yellow, black-edged ocelli ; the ocelli are small, always two on each side of the back ; a series 

 of irregular, transverse, yeUow, black-edged spots along each side of the belly corresponds to 

 these bands. Belly brownish. 



This species was discovered by Captain R. H.' Beddome at Walaghat, on the western slope 

 of the Nilgherries, at an elevation of 3500 feet, in dense moist forests. The specimen sent 

 by him is a male, 14^ inches long. Figures E, E' on Plate XVII. represent the head in two 

 different views, a portion of the side of the body, and the caudal disk : all of the natural size.
