BounENGER! on a single specimen from Ferguson Island (D’Entrecasteaux 
Group).strikingly resembles L. noctua, from which it differs in the fused

G. A. BourENGER, Catal. Lizards, 1887, III. p. 290. 
Two adult specimens from Friedrich- Wilhelmshafen. 
33 and 36 scales round the middle of the body; 40 and 42 subdigital 
lamellae under the fourth toe. Black above, whith five longitudinal golden 
streaks and violet-blue strong metallic gloss. 
Our specimens from New Guinea possess generally 27—36 scales

Guinea. 
39—37 scales round the middle of the body, 33—40 subdigital la- 
mellae under the fourth toe (in one case 44). Body of males shorter than 
that of females; the distance between the end of the snout and the fore 
limb is contained 11/4—11/3 in females, 1—1!/; in males, in the distance

fluent in front with the dark brown lateral colour of the head, extending 
posteriorly on the side of the tail; this dark lateral band edged above with 
a more or less distinct white line or confluent white spots, below with a
