tail. Digits short, not webbed; inner ones well developed, but

 bricated. Eostral nearly twice as broad as high, without distinct

Type No. 5,721, Loo Choo Islands. Collected by Drs. Furness- 

 andHiUer, 1896. 



This species differs from the rest of the genus by the presence of 

 dorsal tubercles, such as are found in most Hemidadylus. In most 

 details of scutellation it closely resembles H. inarmoraitts HailoweU, ^ 

 and I would be disposed to regard them as identical, but the fact 

 that HaUowell refers his specimen to the section dactyloteles of 

 DumerU and Bibron, which included only species with fully clawed 

 digits, makes such a conclusion impossible, and HaUowell' s type 

 being lost, no further investigation is now practicable. 



Japalura polygonata (Hallow.).
