On neio Reptiles and Batrachians from Madagascar. 101 



Island (a female) which may possibly belong to another 

 species, since the band of spots on the primaries are much 

 smaller and their colour less brilliant. Additional specimens 

 can alone settle whether there is a second species in these 

 islands.

P. joesoi similis, eed colore cferuleo saturatioro et minus extensa, 

 iiiargine nigro latiore, macula nigra ad cellulaj anticarum finera 

 haud insulata : subtus mnlto magis nigrieantibus, anticis parte 

 apicali vix pallidiore squamis albidis sparsim notatis, posticia

Ilah. Solomon Islands, Aola in Guadalcanar Island ( G. M. 

 Woodford) . 



A single male specimen in beautiful fresh condition is in 

 Mr. Woodford's collection. The species is closely allied to 

 P. joesa of N. Australia and also to the insect from New 

 Ireland which we attribute to P. Montrouzieri from Woodlark 

 Island. From both of these it ditfers in having the under sur- 

 face of the wings nearly uniform ; the apical portion of the pri- 

 maries, too, is very slightly paler than the rest of the wings.

[Plates V. & VI.] 



Uroplates phantasticus. (PI. V. fig. 1.) 



Head large, oviform in outline, deepest at the ocular region ; 

 interorbital space concave ; snout once and three fourths the 

 diameter of the eye ; the distance between the eye and the ear 

 equals that between the eye and the nostril ; ear-opening 

 minute, not larger than the nostril ; supraciliary edge pro- 

 duced posteriorly in a long, triangular, horn-like lobe, the 

 length of which equals half the diameter of the eye. Limbs 

 slender ; the adpressed hind limb reaches the shoulder. 

 Digits one-third webbed. Body compressed, back tectiform ; 

 a slight, non-denticulated fold from axilla to groin. Scales 

 finely granular, larger on the middle of the belly ; a straight 

 transverse ridge from the supraciliary horn to the interorbital 

 region ; three slight chevron-shaped ridges on the anterior
