Boiga, dendrophila regularis (Boulenger). 



Two specimens. The scale formulas are as follows: 



male: sc. 21; ventr. 236; an. 1; subcaud. 89; supral. 8; 

 oc. 1+2; temp. 2 + 3 and 2 + 4. 



sex indeterm.: sc. 22; ventr. 238; an. 1; subcaud. 110; 

 supral 8; oc. 1+2; temp. 2 + 3. 



They have 56 and 60 yellow cross bars. The Bornean 

 form, with 47 to 68 crossbars and a rather large number of 

 vensrals seems entitled to a trinominal designation, and the 

 variety name given to it by Boulenger, is available, the name 

 annectens being regarded here as synonymous. This tendency 

 of the Bornean specimens to more numerous crossbars and 

 ventrals is well illustrated in the series in the U. S. National 

 Museum which shows the following numbers: 



U. S. N. M. No. 49985, Batoe Panggal, Borneo, ventr. 234, bars 58. 

 49784, — „- 234 — 63. 



51651, Mahakam River — „- 235 - 68. 



38064, Sukadana, West — „— 238 — 60. 



We have therefore detailed record of 10 Bornean specimens 

 with 232—239 ventrals and 47 — 68 cross bars. Against this we 

 have a single record of a specimen in British Museum with 218 

 ventrals (Boulenger, Cat. Sn. Brit. Mus., vol. 3, 1896, p. 71). 



Boiga cynodon (Boie). 

 A single male specimen with the following formula: 

 sc. 23; ventr. 279; an. 1; subc. 149; supral. 9; oc. 1 + 3; 

 temp. 3 + 3. 



The coloration of this specimen, in alcohol, may be de- 

 scribed as „black above; the light cross bars represented only 

 by oval light dots on the scales; belly black, dotted with light 

 on the anterior part; head brownish, speckled with black; a 

 black streak on each side of head behind eye, labials with black 

 vertical lines on the sutures."
