like the back, the white spots becoming smaller towards the 

 tip ; below it is light coloured like the belly, and similarly 

 spotted. All specimens show a swelling at the base of the 

 tail behind the vent, which is followed by a deep fold. The 

 following table gives the measurements of one of the Hermanns- 

 burg specimens and the one collected by Captain "White at 

 Ellery Creek, also those of the type for comparison: —

[Two specimens were taken on Ellery Creek ; unfortunately 



one must have been lest. This is the only locality in which 



we observed this rare lizard.] 



Gehyra variegata, D. and B. — [Very common. Found 

 almost everywhere under bark of trees, and sometimes in 

 decaying logs.] 



Delma fraseri. Gray. — [Several of these snake-like lizards 

 were taken from under fallen logs in the MacDonnell Ranges 

 both east and west of Alice Springs.] 



Lialis burtonii, Gray. — [These strange snake-like lizards 

 were found in the MacDonnell Ranges ; they are very quick 

 of movement, and when a tree trunk or a large stone was 

 turned over they were often mistaken in the first instance 

 for snakes.] 



■Amphibolurus maculatus, Gray. — [Very plentiful in the 

 sandy country amongst the porcupine grass. They run with 

 great rapidity from one tussock* of grass to another, and very 

 often a charge of dust-shot had to be used before they could 

 be procured. We only met with these lizards on the sandy 

 country.] 



Amphiboh/rus reticulatus, Gray. — [The most plentiful of 

 all lizards. They burrow in the sand and are often seen 

 looking out of their burrow entrance or at times basking in 

 the sun. They can run very swifty, and inflict a severe bite 

 on the fingers. They seem to form a large item of food for 

 birds and natives. Although a few were found under stones, 

 they are chiefly confined to sandy country.] 



Amphibohirus barbatus, Cuv. — [An odd one found here 

 and there throughout the expedition, and we found them to 

 vary much in colouration, which is due, no doubt, to protective 

 causes. Those found on the sand and yellow cliffs were light- 

 yellow, sometimes orange; in the red sandhill country they
