lenger’s specimen except in the following details:—Length of 
internasals sometimes equals prefrontals. Postoculars and sub- 
oculars: the numbers of shields in contact with the back of the 
eye, intervening between the supraocular above and the fifth 
labial, are four in two specimens on both sides, four in one 
specimen on one side, five in two specimens on both sides, five 
in two specimens on one side, six in one specimen on one side. 
Labials eight with third and fourth touching the eye on one 
side, nine with fifth only touching the eye on one side. Ventrals 
and subeaudals 140+73, 139+ 2%, 139 +73, 138+ 2, 1388+72 (tip

22. OpistHoTROPIS ANDERSONII. Hongkong,—TI obtained five 
specimens, all from Hongkong Island. They were all captured in 
a swamp near the Sanatorium on the Peak, whilst being drained 
during the campaign against malarial mosquitoes. One was dug 
up ata depth of about 2 feet below the surface. They accord 
with Mr. Boulenger’s description except in the following parti- 
culars :—Labials are inconsistent in arrangement. Thereare nine 
in one specimen on one side, eight in all the rest. The fourth 
and fifth touch the eye in one specimen on one side, the fifth 
only touches the eye in two cases on both sides, and in one case 
on one side, no labials touch the eye in two specimens on one 
side. Preoculars (including the suboculars of Boulenger) are 
two in two specimens on both sides, two in two specimens on one 
side, one in one specimen on one side, and three in one specimen 
on one side. The anterior chin-shields are in contact with five 
lower labials in two specimens on both sides, and in one specimen 
on one side, with four in one specimen on both sides, and in 
one specimen on one side. Ventrals and subcaudals 167+ 60, 
149+53, 164+59, 1654+59. Colour uniform dull olive-blhuish 
above, lower half of ultimate row and belly yellow. Lower labials 
and throat-scales with dull bluish mottling. Sparse mottling 
beneath tail.
