Nostril pierced iu the nasal plate. Palatine bones in contact on the 

 median line of the palate. Tympanum not covered with integument. 

 Pterygoid bones in contact on the middle line. Eyelids movable; 

 digits with nouretractile claws. Supranasal plates wanting. Lower 

 eyelid with a transparent disk; two frontoparietal plates; digits 5-5. 



This genus embraces twenty-eight species, all of which are referred 

 to Lygosoma, Section IV, iu Bouleuger's Catalogue of the Lizards in 

 the British Museum. Of these, five are from New Zealand ; five are 

 from Australia and adjacent islands; four are from the Pacific islands 

 and New Guinea; three are from the Philippines; six are from India; 

 one from the Mauritius; two from West Africa; and one, the species 

 described below, is from North America, and, according to Boulenger, 

 from China. South America and (excepting China) the temperate parts 

 of Asia and Europe are not. possessed of any species of Liolepisma. 



The genus is markedly diflferent from Eumeces in the absence of 

 internasals, the frontal coming broadly in contact with the rostral as 

 well as the nasals. The palate has a triangular notch running to a 

 point instead of being more linear and hollowed anteriorly. There are 

 no pterygoid teeth as in Eumeces. The tongue appears flatter and 

 more extensible at the tip.

Body slender, quadrangular; vent rounded, attenuated one and one- 

 half times the body; frontal in contact behind with the vertical, before 

 with the rostral; the prefrontals small; lateral. Nasal above the first 

 labial, in contact above with the internasal; the postnasal and oneloral 

 in contact with the postfrontal. Seven upper labials. Ears large, 

 vertical. Lower eyelid transparent in the center; without scales. 



Scales very thin aud membranous; generally 28 rows around the
