Variations. — Five other specimens from Jolo Archipelago are 

 in the collection. They agree with the above description with 

 few exceptions. One specimen has two pairs of nuchals, a second 

 has the frontoparietals fused. All save the one described have 

 twenty-eight scale rows. A young specimen in the collection 

 is olive brown above. None of the specimens show evidence 

 of carinations on scales. 



Remarks. — This is the first record of this species from the 

 Philippines. Its occurrence is hardly a matter of surprise, since 

 de Rooij has identified Mocquard's Lygosoma whiteheadi from 

 North Borneo as a synonym of this species. 



The specimens obtained in Jolo Archipelago are from the 

 following islands: Siet Lake, Jolo, 2 specimens; Lapac, 1; Bon- 

 gao, 1 ; Simonor, 1 ; Tawitawi, 1. This species is also known 

 from Borneo, several localities; Java; Celebes; Malacca; Siam; 

 Burma; Hongkong. 



Emoia atrocostatum Lesson. 



It was observed or taken on all the islands visited ; especially 

 common along the coasts; numerous specimens were preserved. 



Emoia cyanurum Lesson. 



This species was taken only on Tulian, a small uninhabited 

 rocky island near Jolo. It was not observed elsewhere. In 

 the Philippines it is common on certain islands along the coast 

 of Palawan. It is a matter of no small surprise that it was 

 not taken or observed on the other Sulu Islands. If it is present, 

 it is probably rare. Two of the specimens taken have brilliant 

 blue tails with three greenish golden stripes on the back from 

 snout to tail. 



Dasia smaragdinum Lesson. Plate III. 



Specimens were taken on Great Govenen and Bongao Islands. 

 In the first locality they were especially numerous. Dorsally
