Vor. III] VAN DENBURGH—REPTILES—CHINA, JAPAN, FORMOSA 257 
Including those mentioned above, twelve specimens are 
known to have been taken on Amami O shima. Of these, 
six have only the median dorsal black line; five have a lateral 
line on the third and fourth row of scales of each side, more 
or less clearly indicated; one, examined by Dr. Wall, had indi- 
cations of another line on each side, making five lines as in 
Ai. boettgeri, but much narrower and less intense. 
No. 22063 contained the remains of an Achalinus (No. 
22065) which it had eaten. 
Hemibungarus boettgeri (Fritze) 
We have received two specimens of this snake, but, unfor- 
tunately, neither bears an exact locality-label. Both were 
purchased in Kyoto, Japan, and one is labeled “Formosa ?” 
while the other is from the Loo Choo Islands. The latter, No. 
16470, has 221 gastrosteges, and eighteen dorsally complete 
black rings on the body with two on the tail. There can be no 
doubt that the specimen labeled “Formosa?” also came from 
the Loo Choos. It has two small maxillary teeth, 207 gastro- 
steges, 29 urosteges, 13 scale rows, and 13 body rings. The 
only difference between Hemibungarus boettgeri and H. jap- 
onicus is found in the number and character of the longitudinal 
black lines. Although it has been shown that H. japonicus 
_ may have either one, three or five lines, these lines seem always 
to be much narrower and less intense than in H. boettgeri. 
Thus far, all (ten) specimens of the H. boettgeri type of color- 
ation which have any definite locality assigned, have been se- 
cured in Okinawa, while all the (twelve) definitely labeled 
H. japonicus have come from Amami O shima. It would 
seem, therefore, that the Hemibungarus of Okinawa is differ- 
ent from that of Amami O shima, and that they must be recog- 
nized as distinct species until more definitely intermediate 
specimens are discovered.
