the fifth only entering the orbit. Ventrals 187; subcaudals 44. 
Pupil vertical. Whitish, with a vertebral series of large subqua- 
drangular square spots ; a dark-brown horizontal stripe behind the 
eye; and a spot of the same colour below the eye. Lower parts 
whitish. 
A single specimen, 12 inches long (tail 14 inch), is in the late Dr. 
Jerdon’s collection. It is rather shrivelled; and unfortunately no 
record as regards the locality where it was found was placed on the 
bottle. He obtained it probably within the Himalayan region or in 
Khassya. 
Dipsas NUCHALIS. 
Allied to D. gokool, but with a widely different coloration. Scales 
in twenty-one series, those of the vertebral series much enlarged, 
subhexagonal. Ventrals 233-242; anal single ; subcaudals 
90. Eye of moderate size. Loreal square ; one preocular, 
just reaching the upper surface of the head ; two postoculars. Hight 
upper labials, the third, fourth, and fifth of which enter the orbit. 
Temporals 2+3+43,; asmall odd temporal is intercalated between 
the anterior temporals and the postoculars. Upper parts light pur- 
plish brown, with a vertebral series of brown transverse spots which 
gradually become indistinct towards the middle of the length of the 
body, and further on disappear entirely. The first spot on the neck 
is a narrow transverse bar. An oblique narrow black temple-streak. 
Upper parts of the head nearty uniform brown. Lower parts yel- 
lowish, densely powdered with purplish brown. 
Several specimens were found by Col. Beddome in the forests on 
the western coast of Malabar ; the largest is 44 inches long, the tail 
measuring 10 inches. 
OPHITES SEPTENTRIONALIS. 
Scales in seventeen rows, only those in the middle of the back 
feebly keeled. Ventrals 214 ; anal single ; subcaudals 83. Anterior 
frontals short, much broader than long; vertical five-sided, rather 
longer than broad. Nostril wide, situated between the two nasals, 
the anterior frontal, and the first labial. Loreal narrow, much longer 
than deep. One preocular just reaching the upper surface of the 
head ; two postoculars; eight upper labials, the third, fourth, and 
fifth entering the orbit. Temporals 2+3. Black, trunk with 
thirty narrow white rings, only about two scales wide ; the first at 
some distance behind the head. Lower parts white ; subcaudals 
marbled with black. 
One specimen from the late Dr. Jerdon’s collection, without indi- 
cation of its habitat. But there is no doubt that he obtained it 
during his last journey through the northern parts of India. It is 
pe inches long, the tail measuring 8 inches. 
TRIMERESURUS JERDONII. (Plate XXXIV.) 
The second upper labial shield forms the front part of the facial 
pit ; one or more small shields between the supranasals. Scales on
