516 ON SNAKES FROM JAPAN AND THE LOO CHOO ISLANDS. [Dec.12, 
are 204428, 183+28, 194430, 202+ 2, 197427, 1294 29. 
Two specimens from Amami agreed in having three longitudinal 
dorsal, black lines, narrower than the pink intervals. One of 
these had indications of another line in the flanks on each side. 
One had 12 and the other 14 black annuli. Both were peculiar in 
that the last ventral was divided, a condition which obtains in no 
other specimen, and this may constitute a separate species. The 
ventrals and subeaudals were 2084+ 29 and 198+28. The remaining 
two specimens from Amami were pale pink with a single, narrow, 
vertebral black line. One had 15 and the other 13 black annult, 
and the ventrals and subcaudals were 215+ 28 and 214430. One 
of the Okinawa examples had swallowed a lizard measuring 
41 inches. The snake was 1 foot 73 inches in length, and the 
lizard occupied a position entirely posterior to the tenth inch im 
the snake’s length. The stomach was therefore placed unusually 
far back in this species, and I have noticed a similar peculiarity 
in an allied snake, Bungarus candidus, in India, 
Family ViPERIDA. Subfamily CrotaLIné.

8. LACHESIS OKINAVENSIs.—Of eight specimens four were from 
Okinawa, three from Amami, and one from Yaku. ‘The scales were 
93 in mid-body in all except one specimen, where they were 24. 
The subocular was broken up in two specimens. ‘The ventrals and 
subeaudals were 131+44, 134446, 127+42, 128446, 128+ 46, 
and 129+42. One had swallowed a small shrew-like animal. 
9, LacnEsis FLAVoviRIDIs.—Of 41 specimens, 21 were from 
Amami and 20 from Okinawa. The ventrals were 232 in one 
specimen, 234 in another. ‘The scales were 40 in mid-body in one 
specimen. Many were quite young, hatchlings apparently ; six 
such varied in length from 1 foot 64 inches to 1 foot 9# inches. 
One had swallowed a rat. The fang of one large specimen was 
+2" measured straight. 
10. LAcHEsIs MUCRosquAMATUS.—Of four specimens, three were 
from Miyako and one from Iriomote. I have no hesitation in con- 
sidering these specimens as belonging to this species, though it 
extends the habitat considerably. They agreed with the specimens 
T have examined in the British Museum Collection. A pair of 
internasals was present. ‘Two to four rows of temporals were 
smooth. The scales were 23 in mid-body in two specimens, 24 in 
another, and 25 in the fourth. The ventrals and subcaudals were 
186466, 1902477, and 185472.
