tongue almost completely united with tlie floor of the mouth. Vomerine 

 teeth consisting of series of about six granules situated upon two ridges ; 

 these are separated on the median line of the ])alate, and are situated 

 between,- or slightly behind, the choanae. as in L. hochstetteri. 



Fingers longer than in L. hochstetteri, the first shorter than the second : 

 eacli palm with a large inner and a small outer metacarpal tubercle. The 

 tibio-tarsal articulation reaches the nostril when the hind leg is carried 

 forward along the side of the body. Toes longer than in L. hochstetteri, 

 webbed at the base ; a small, flat inner metatarsal tubercle is present. 



Subarticular tulxn-clcs of fingers and toes distinct. The skin is nearly 

 everywhere smooth, though there are some scattered tubercles on the 

 proximal portions of the thighs and shanks. No omosternum ; sternum 

 (fig. 1) two slender diverging cartilaginous styles, and of similar forjuation 

 to L. hochstetteri (fig. 2) ; the left epicoracoid cartilage overlaps the right in 

 both Sjjecies. Dia|/ophyses of sacral vertebra (fig. 4) subcylindrical basally, 

 and slightly expanded distally. Short ribs articulate with the anterior 

 diapo]>liyses. 



Colour. — Light brown in life, with irregular darker and lighter marbling 

 on the upper surfaces. A black band extends from the tip of the snout to 

 the nostril and thence to the eye ; it is continued backwards towards the 

 sides below the dorso-lateral ridge. The limbs are marked with oblique 

 black cross bands, which are most })rominent on the thighs. Under- 

 surfar-es with greyish mottlings. 



The foregoing description is based upon a s[)ecimen 42 mm. long from 

 the snout to the vent ; it is the example figured in Plate XXX, and is 

 selected as the holotype. A second specimen about the same size, and 

 collected with the first, was dissected to examine the internal characters. 



Variation. — Two other examples, received in alcohol, differ only in being 

 somewhat more iiniformly coloured, their black markings being more or 

 less obscure. 



Identitif. — This sjjecies differs from L. hochstetteri not only in its more 

 slender form, but in having much longer fingers and toes, the webs of 

 which are more reduced than in that species. The tongue is narrower and 

 not so free posteriorly. 



The holotvpe and paratype are deposited in the Dominion Museum, 

 Wellington. 



Habitat. — Stephen Island, Cook Strait. 



T am indebted to Dr. J. Allan Thomson for the privilege of describing 

 this iiit(>resting new s})ecies, which is named after its discoverer, Mr. Harold 

 Hamilton. 



SUPPLEMEXTARY NOTE BY ChARLES HeDLEY, F.L.S., AUSTRALIAN MuSEUM. 



This interesting addition to the fauna of New Zealand was discovered 

 by Mr. Harold Hamilton on Stephen Island, at the north-west extremity 

 of Cook Strait. This small island is also noteworthy as a refuge of the 

 tuatara, or Sphenodon. Dr. J. Allan Thomson subsequently visited the 

 island and obtained further material. After several days of fruitless 

 search, fourteen specimens were found crowded under a large heap of stones. 

 As it was in July, Dr. Thomson suggested that this party may liave been 

 hibernatino-. During the winter there are a few streams on the island, 

 but in summer all the surface water disappears. This suggested to 

 Dr. Thomson that jjossibly the LiopeJma is viviparous. On the other hand,
