224 Indian and Malayan Amphibia and Reptilia. [No. 3, 



top of head ; below whitish, all over sprinkled with dai'k, bases of ventrals 

 blackish, tail below mostly black. 



g. Total length 44 inches, tail 5f " ; length of head 2\' its width at base 1 \ /', 

 31 series of scales ; ventrals 176, subcaudals 62 ; light brown with numerous 

 pale scales, the lateral white band partially yellow, top of head with indistinct 

 dark and pale spots. 



h. Total length 48£", tail 6f ", head 2|", its width at base If" ; ventrals 178, 

 Bubcaudals 63 ; general color greenish brown with pale spots, each scale of 

 the lateral white band has a distinct yellow spot. This is the largest specimen 

 observed. 



From what I have already noticed there can be no donbt that the 

 present species is quite distinct from either, T. viridis or gramiaem, 

 of which B 1 y t h considered it at one time to be only a variety. 

 The great number of small, cariuated scales which are almost 

 granular on the head is especially characteristic for T. Cantoris. 

 In B 1 y t h ' s original description the number of subcaudals should 

 be 76 instead of 214, which is a misprint, the number of ventrals is 

 about 180 in the type specimen, which is, however, considerably 

 injured and shrunk. The species is very common on the Nicobars 

 and also occurs on the Andamans. 



81. Trimeresurus convictus, n. sp. PI. XII, Fig. 1. 



Body stout and short ; scales rhombic, moderately keeled in 21 

 series; ventrals 132, anal entire, subcaudals 29; head broadly 

 eliptical, covered with largish, smooth scales ; rostral very high, 

 obtusely truncate above with a small shield adjoining, behind which 

 a pair of largish suprarostral shields forms a suture, two other shields 

 on either edge between them, and then follow the supraciliaries 

 which are very large and broadly rounded posteriorly ; the second 

 upper labial forms the front of the facial pit ; numerous small 

 shields between the lower edge of the orbit and the upper labials, 

 which are eight in number. 



Color, above, pale brown, with minute dark specks ; head uni- 

 form dark brown, with a small yellowish spot in the middle of the 

 tympanoid region, a U-niark on the neck, and a series of large 

 quadrangular more or less confluent or alternating brown spots along 

 the back, sides marbled with brown and pale yellow, one series of 

 brown spots above the bases of the ventrals being rather more con- 

 spicuous than others ; below, greenish or yellowish white, all over
