114 BARBOUR: ZOOGEOGRAPHY. 



Lycodon subcinctus Boie. 

 BoiE, Isis, 1827, p. 551. Boulenger, Cat. snakes Brit, mus., 1893, 1, p. 359-360. 



Type locality: — Java {fide Schlegel, Essai phys. Serp., 1837, 2, p. 117). 



In the Museum there are three specimens of this species from Batavia; 

 and there is one in the Bryant collection, from Depok, with perfectly smooth 

 dorsals, but otherwise typical. The apparent absence of this species from 

 Buitenzorg or higher altitudes would make it seem almost certain that it is most 

 common in, if not entirely confined to, the coastal lowlands. In each case eight 

 , supralabials are present, and there is no preocular; in two the anal is divided, 

 while in the third it is entire. 



Range: — Malay Peninsula, Great Sunda Islands (except Celebes), PhiHp- 



pines. 



Lycodon striatus (Shaw). 



Shaw, Gon. zool., 1802, 3, p. 527. Boulenger, Cat. snakes Brit, mus., 1893, 1, p. 349-350. 



Type locality: — India. 



This Museum has specimens of tliis generally scarce form from various 

 localities in India. It is also known from Transcaspia and Ceylon. 



Lycodon aulicus (Linn£). 

 LiNN^, Syst. nat., ed. 10, 1758, 1, p. 220. Boulenger, Cat. snakes Brit, mus., 1893, 1, p. 352-354. 



Type locality: — "Habitat in America." 



This form is one of the most widely distributed of Asiatic reptiles, as well 

 as one of the most variable in coloration. In many parts of India it is extremely 

 abundant, notably in the vicinity of Lucknow, where it was common during 

 November, 1907, in swampy lowlands, especially near ponds and tanks. There 

 are in the collection here specimens from Pondicherry, Madras, Amballa, Bom- 

 bay, Lucknow, in India; Pegu and Rangoon, in Burma; Ceylon; Singapore; 

 Bangkok, Siam; Java, Philippine Islands, and Bourbon. In the last locaUty 

 it was undoubtedly introduced, probably very early, as the specimen here is an 

 old one obtained by exchange from Dumeril. There is a specimen from the 

 same locality recorded by Boulenger in the British museum. This species, 

 judging, from several stomachs contents, feeds almost exclusively on scincoid 

 lizards. It may be noted that the extent of contact between loreal and inter- 

 nasal varies extremely in individuals. They are always in contact, but fre- 

 quently only to a slight extent. 



Range: — India and Ceylon to Cochin China; through the Malay Archi- 

 pelago, as far east as Celebes and Timor. 



A specimen taken at Buitenzorg, April, 1907, belongs to Boulenger's var. D;
