NEW LIZARDS AND A NEW TOAD FROM THE DUTCH 

 EAST INDIES, WITH NOTES ON OTHER SPECIES. 



BY THOMAS BARBOUR. 



The identification of the herpetological material which I col- 

 lected in the East Indies during a part of 1906-7 has just been 

 completed. I find some pointsof interest regarding geographic 

 races in several of the species, and then/ are other specimens 

 which can not be referred to any form described up to the 

 present time. A complete list is now almost ready but it seems 

 advisable to publish the following preliminary descriptions. 



Leiolepisma pullum sp. now 



Type. — Xn. 7486, Museum of Comparative Zoology, from Humbolt's 

 Bay, Dutch New Guinea, collected by T. Barbour, January, 1907. 



Closely related to L. fuscum ( I). & B. ) and L. beccarii I Ptrs. & Doria), 

 but differing from both these species as the appended description shows: 

 Habit lacertiform. Fingers four, toes five; distance between the end of 

 the snout and the fore-limb contained once and one-fourth in the distance 

 between axilla and -ruin ; snout obtuse. Lowereyelid with an undivided 

 transparent disc, smaller than the ear-opening. Nostril pierced in a single 

 nasal; supranasal absent; frontonasal much broader than long, broadly 

 in contact with the rostral, and very narrowly in contact witli the frontal ; 

 latter shield a little shorter than frontoparietal, in contact with the first 

 and second supraoculars ; four supraoculars, seven superciliaries ; fronto- 

 parietal single, followed by a small interparietal, parietals forming a median 

 suture; a pair of nuchals, and a pair of temporals border the parietals; 

 four labials anterior to the subocular. Ear-opening oval, larger than the 

 transparent disc; auricular lobules present, and entering the aural aper- 

 ture from all sides. 42 rows of scales round the body; dorsals and laterals 

 all distinctly tricarinate; preanal scales very slightly enlarged. The hind 

 limb reaches a little beyond the anterior side of the fore-limb. Subdigital 

 lamellae under the fourth toe, 32. Tail almost exactly twice as long as 

 head and body. Color dark mahogany brown above, uniform except for
