1. TRopmonorus pryert.—Of 58 specimens, 54 were obtained 
from Okinawa, three from Amami, and one from Iriomote. There 
were two postoculars on one side in one specimen. Four contained 
eggs with no trace of embryos.

The size of the eggs first alluded to 1s very remarkable con- 
sidering the size of the species. The mother measured 2 feet 
2 inches, tail slightly docked. 
9. DInopon RUFOZONATUS.—OF eight specimens two were from 
Miyako, two from Ishigaki, four from Iniomote. The two speci- 
mens from Miyako were peculiar in colour, being of a much lighter 
brown than usual. Each had 21 whitish, dark-margined dorsal 
bars. The ventrals were 182 and 189. 
3. DINODON SEMICARINATUS.—Of 22 specimens, 19 were from 
Okinawa and three from Amami. The supralabials in one were 
eight with the fourth and fifth only touching the eye. One had 
swallowed a fledgling, and another a lizard. 
4, ConuBer scuMACKERI.—A single specimen, much mutilated 
and of large size, was obtained from Ishigaki. The supralabials 
were nine on the right side with the fifth and sixth tonching the 
eye, ten on the left side with the sixth and seventh touching the 
eye. The loreal was more than twice as long as high. The upper 
of two preoculars nearly touched the frontal. 
5. ABLABES SEMICARINATUS.—Of 134 specimens, 131 were from 
Okinawa and three from Amami *. 
6. ABLABES HERMIN#.—The single specimen was from Iriomote. 
It was an aberrant example in that the scales number 19 in mid- 
body. Anteriorly and posteriorly the normal 17 scales were 
present. Ventrals 159 and subcaudals 60. 
7. Hemipunearus sAponicus.—Of ten examples, six were from 
Okinawa and four from Amamit. Those from Okinawa were all 
alike in having five longitudinal black dorsal lines broader than the 
ink intervals. There were 9-12 narrow black annuli round the 
body and 1-2 (2 usually) on the tail. The ventralsand subcaudals 
* There seems but little doubt that Japan has been incorrectly included as a 
habitat for this species and for Hemibungarus japonicus. Boulenger is clearly of this 
opinion (vide op. cit. vol. 111. p. 395 footnote). These species were originally described 
and figured by Giinther (Ann. & Mag. Nat. Hist. (4) i. 1868, pp. 418 & 428) from 
one specimen of each reported to have come from Nagasaki. Thirty-seven years 
have now elapsed without either being rediscovered in Japan,
