(Text-liguies 3 &, 4.) 



Several interesting collections from the Australian Region 

 have recently been received by the British Museum (Nat. Hist.). 

 I shall include four in this one paper, and limit it for the sake of 

 brevity to notes on rarities and descriptions of new species. 



I.— NEW GUINEA. 



Mr. W. Potter recently collected for the Museum in N,E. New 

 Guinea, and besides large series of the commoner things, obtainerl 

 several rare lizards and a new skink. The latter I have named 

 after Mr. C. J . Battersby, avIio lias been a most helpful assistant 

 to me throughout the time that I was in charge of the Museum's 

 collections of Reptilia and Batrachia. 



LACERTILIA . 

 Geckonid^, 



G\MNODACTYLIS hOniJE Blgr. 



A male (length : head 45 mm., body 110 mm,, tail missing), 

 at least twice as large as the male type-specimen, the onl}' 

 individual already in the Collection ; in other particulars the 

 two specimens are identical. 



Gv'JVtNOUACTYLUS LOUISIAUENSIS de Vis. 



A very large well-preserved female (length : head 35 mm., 

 body 93 mm., tail 47 mm.). The three specimens of this rare 

 Gecko already in the Museum are from the D'Entrecasteaux Group 

 and the Solomon Islnnd-s. 



P Y G O r O D I D yE . 

 LlALIS .TTCAni 1^1 gr. 



One adult of this extremely rare Pygopod was collected at 

 Lababia. Each dorsal scale, with the exception of the two 

 median series, has a small black apical dot, and is also finely 

 speckled. The species was only known from the three type- 

 specimens.
