ruiuiinj,' along tlie back, breaks up into spots. These 

 may be so bi'oken up as to represent a chain of s])ois only, but 

 the above pattern is always traceable. A light oeainy dorsal 

 stripe extending from the tip of the snout to the anus is always 

 pi'esent. A dark brown band commences on the tip of the 

 snout and continues to above the arm. A dai'k spot on the 

 ui)perlip beneath the eye. Ui)i)er surface of shank barred with 

 bi'own. Under surfaces cieaniy white, throat speckled with 

 brown. 



Length of largest specimen (snout to vent) 56 m.m. 



Width of head ^5 m.m. 



Length of head (to level of tympana) 20 m.m. 



Length of outstretched hind limb 80 m.m. 



Examples of var. ///y//Vr/ never attain the dimensions of the 

 lai-gest specimens of var. il/iiut'rilii, the western form, so far as 

 is known, never exceeding 60 m.m. in length. 



Jjoc-i. — Properly localised specimens of var. ti/iiica would 

 appear to be rare in collections. Jt is, as far as 1 am aware, 

 recorded from the following places only. — Houtman Abrolhos, 

 Western Australia (Giinther, 1858, and Boulenger, 1882), 

 Geraldton and Perth, Westeria Australia (Fletcher, 1898), 

 Eighty miles South of Perth (Austr. Mus.), King George 

 Sound, Western Australia (Krefft, 1867 as L. bibrniill, see be- 

 low, p. 32), Port Essington, Northern Territory (Giinther, 

 1858, and Boulenger, 1882). 



There are no records of this or any other frogs occurring 

 between King George Sound and Spencer Gulf in the Great 

 Australian Bight, and, as the country is almost devoid of water 

 permanent enough for breeding purposes, it seems improbable 

 that any will be found there. However, as our knowledge of 

 the distribution of fi-ogs in St)uth and Western Australia is 

 very meagre, it is quite possible that some of the burrowing 

 forms wdll be found to have adapted themselves to the un- 

 favourable conditions of the Bight county as they have done in 

 Central Australia. Another stretch of country where the 

 occurrence of L. dor.'iaJix is as yet conjectural, is between 

 Geraldton on the West coast and Port Essington in the Northern 

 Territory. But, as the present known distribution of this frog 

 points to its having reached South-Western Australia by Avay 

 of the North West coast, it seems reasonable to presume 

 that it still occurs there.
