Oligodon sdbgeiseus. (Plate XIX. fig. F.) 



Oligodon subgriseum, Dum. ^ Bibr. vii. p. 59. 



Scales in fifteen rows. Loreal distinct (exceptionally confluent with posterior frontal) ; 

 one prseocular, two postoculars ; seven upper labials, the third and fourth entering the orbit ; 

 temporals 1+2. Ventral shields 180(-187-189)-202 ; subcaudals 48-54. Head with sym- 

 metrical brown, black-edged markings ; back with numerous, narrow, rather irregular, reti- 

 culated cross streaks, formed by the black edges of some of the scales, and interrupted by 

 three more or less distinct, narrow whitish lines, one of which runs along the vertebral line. 

 Belly uniform white : some specimens have a minute black dot on the lateral edge of every 

 second or third abdominal shield. 



This species inhabits the southern parts of the peninsula of India ; Capt. R. H. Beddome 

 found it in the Anamallay Mountains ; our largest specimen is 1 9 inches long. 



Figure F on Plate XIX. shows the coloration of the back. 



Oligodon spilonotds. (Plate XIX. figs. E, E'.) 



Scales in fifteen rows. Loreal distinct; one prseocular, two postoculars; seven upper 

 labials, the third and fourth entering the orbit; temporals 1-f 2. Ventral shields 155-162 ; 

 subcaudals 50*. Head with symmetrical brown, black-edged markings: an angular band 

 across the forehead, descending obliquely through the eye ; a second on the crown, descending 

 to the angle of the mouth, separated from the nuchal band by a yellowish interspace ; nuchal 

 band nearly as large as the head, and covering the extremity of the occipitals. Back with 

 about seventeen large 8-shaped brown, black-edged transverse spots ; they are distant from 

 one another, the middle of each iaterspace between them being occupied by a narrow trans- 

 verse stripe formed by the black edges of some of the scales ; the transverse bands and stripes 

 become gradually similar to one another on the hinder part of the body. Lower parts uni- 

 form white. 



We have received this species from the Madras Presidency. The largest of three speci- 

 mens is 15 inches long; we have given two views of its head (E), and one of a portion of 

 its body (E'), to show its coloration.
