Barbow — New Lizards and New Toad from Dutch East Indies. 17 



D. smaragdinum moluccarum subsp. nov. 



Type. — Adult from VVahaai, Ceram ; Museum of Comparative Zoology; 

 No. 74X1, T. Barbour, collector. 



The coloration of this may be described as that of a light gray ground 

 color, more or less irregularly spotted and blotched with dark brown and 

 black, giving what is commonly called a salt-and-pepper appearance. 

 The writer has seen an enormous number of these lizards alive in very 

 many localities, and his notes, made in the field, show that no variation 

 from these conditions came under observation. 



I have published the only known record for D. smaragdinum occurring 

 in Formosa (Proc. N. E. Zool. Club, IV, Nov., 1909, p. 05). This was a 

 young example and hence can not be definitely placed in a particular 

 color phase as all the young seem to have a more or less similar color 

 pattern. 



Colored drawings based upon notes made in the field have been made 

 to illustrate these three races.

This very widely distributed species is undoubtedly frequently carried 

 about l>y human agency, and therefore it appears colonized in certain 

 localities where no definite local races have arisen. However, local races 

 seem to occur which often may be recognized by a definite color pattern, 

 where, as in I), smaragdinum, structural differences do not seem to have 

 become definitive as yet. Thus we have from the Bonin Islands C. b. 

 nigropunctatus (Hallowell); from Papuasia, C. b. peronii (Cocteau); 

 while Carman has described and provided notes on others (Bull. M. C. Z. 

 LII, 1, p. 12, June, L908). He has proposed the varietal name paschal is 

 for those upon Easter Island, based upon differences which " may at least 

 he said to indicate the process of forming new species by means of heredi- 

 tary tendencies in variation." Lizards from other islands have been 

 discussed as though they represented full species. Thus, Carman con- 

 siders C. nigropunctatus as of equal value to C. boutonii, from which it 

 has undoubtedly been derived; and he speaks of G. poecilopleurus as a 

 full species " likely to have sprung from C. boutonii." These forms are 

 all better considered as geographic races of a single species; and only 

 trinomial names express this condition. From the East Indian area we 

 know, besides peronii, the subspecies furcata, of which Max Weber col- 

 lected and described five specimens which did not vary in color. My 

 examples from New Guinea, Jobi, and Waigiu all fall under peronii; 

 while on the other hand examples from Bali and Lombok differ widely 

 in coloration from others hitherto described, and may, 1 believe, with 

 justice be considered to represent two other undescribed local races, judg- 

 ing by what we know of the distribution of the species as a whole. Thus 

 from Bali we have
