without a free distal phalanx, clawless; underside of. tail with a mediau 

 series of large transversely dilated plates. 



Only the typical species has a very wide distribution, the others being 

 much more local, except one which occurs in Australia. 



Peropus has lately been put aside for Dactyloperus (and Gehyra by 

 those who regard the two as identical) on the ground that it was pre- 

 occupied by a genus of fishes, the Peropus of Lay and Bennett,' the date 

 • being given as 1831, while Wiegmann's Peropus only dates from 1835. 

 But there is ample proof- that the Zoology of the Blossom was not pub- 

 lished until 1839 or 1810, although printed many years before.

In Boulenger's Catalogue of Lizards Grirard's D. insulensis is sepa- 

 rated as possessing no i^ost-femoral fold, a proceeding warranted by the 

 fact that Girard in the description fails to mention the fold. In the 

 only one of Girard's specimens preserved (No. 21219, U.S.N.M.) the fold 

 is well developed, and the distinction falls to the ground. This speci- 

 men agrees closely with ten others from Kauai and Oalni before me, 

 which in turn prove themselves indistinguishable from the well-known 

 and widely distributed P. mutilatus. 



I have compared the Hawaiian specimens with a topotype of ff. 

 pcronii from Mauritius (No. 16308, U.S.N.M.) and find no tangible differ 

 ences. Manila specimens are not at hand, but I have no doubt that the 

 result would be the same if they were. I may add that Professor
