again the point made elsewhere about the closer Papuan relationship with this 

 island than with other of the Moluccas (c/. the notes on Ceram, p. 38-40). 



Cryptoblepharus boutonii (Desjabdin).

Type locality: — Mauritius. 



Sufficient material is not on hand to attempt to straighten out the probable 

 validity of many of the "varieties" which have been suggested. So far as 

 concerns the material which Boulenger had, one can see that the "varieties" 

 are apparently rather regularly distributed. They are probably real geographic 

 races, for Stejneger (Bull. 58, U. S. nat. mus., 1907, p. 225) has shown that there 

 is a definite condition found in all Bonin Island specimens, so far as seen. He 

 had examined ten examples; and four others here, from Hahashima, Bonin 

 Islands, confirm his observations. Regarding the other individuals which I 

 have studied, I find nothing new to add to what has been said in Proc. Biol, 

 soc. Washington, 1911, 24, p. 17-8. 



The difference between the races pointed out in Dasia smaragdinum and in 

 this species may be distinguished better from the colored figures than by lengthy 

 verbal descriptions. PI. 3, fig. 8, represents the type of C. b. balinensis Bar- 

 bour. PI. 3, fig. 5, represents the type of C. b. cursor Barbour. PI. 3, fig. 7, is 

 of C. b. peronii (Cocteau) from Saonek, Waigiu Island and PI. 3, fig. 6, shows 

 what has been called C. b. peronii (Cocteau) from Madagascar. 



Dibamus novae-guineae Dumerii, et Bibron.

Type locality: — New Guinea, almost certainly from the Dutch section. 



A single typical example from Wahaai, Ceram; its presence on this island 

 was to be expected, even if it had not been previously taken. 



This curious lizard has a far wider range than for a long time was supposed. 

 It is known from New Guinea; Waigui; Ternate, Halmahera, and now Ceram, 

 in the Moluccas; Celebes; Sumatra; and the Malay Peninsula. This is the 

 only land-reptile of burrowing habits, — in other words, which is not carried 

 about fortuitously, — whose range extends from Malaya to Papua without any 

 apparent specific differentiation. It is probably a form whose degradation 

 ' began in very early times. Boulenger speaks of the genus as one "which appears 

 to stand in the same relation to the Scincidae as Anniella to the Anguidae." 



The only other Dibamus known comes from the Nicobar Islands.
