MYSOL. 41 



Catalogue as coming from Mysol; others are records taken from the collections 

 reported upon by Peters and Doria, and others. 



No turtles nor crocodiles appear among the definite records up to the present 

 time. Boulenger has recorded ^ Gekko nionarchus (Dum. & Bibr.) on the basis 

 of a male antl female in the British Museum. G. vittatus Houttuyn appears, 

 as might be expected. *Draco lineatus Daudin occurs, as well as *Calotes cris- 

 tatellus Kuhl. 



Few seines are recorded. They are Tiliqua gigas (Schn.), Dasia smaragdi- 

 num (Lesson), Leiolepisma fuscmn (Dum. & Bibr.), and Eitwia cyanurum (Les- 

 son). Many more surely remain to be found. 



Of snakes we know only very few. Typhlops olivaceus (Gray) is said to 

 occur, but this is almost certainly an error, for the species occurs elsewhere only 

 in the Philippines and Borneo. Python amethijstinus (Schn.), Emjgrus carinatus 

 (Schn.), and E. asper (Gthr.) are recorded. The last here reaches the western 

 limit of its range. Stegonotus modestus (Schlegel), *Dendrophis pidus (Gmelin), 

 Boiga irregularis (Bech.), *Chrysopelea rhodopleuron Boie, and Pseudelaps 

 muelleri (Schl.) close the list of reptiles. 



There are three species of amphibians. Hyla amboinensis Horst is found 

 only upon this island and Ambon, which is the type locahty. The wide-ranging 

 H. dolichopsis (Cope) occurs, while H. aruensis Horst was originally described 

 from both the Aru Islands and Mysol. It possibly occurs in Papua also. 



Now, it will be seen by looking at these notes that we have to deal with 

 certain species reaching this island from the west which are on Ceram but not 

 on Halmahera, though other species are of course also found on that island as 

 well. However, the series of species as a whole shoWs a much closer relationship 

 to that of Ceram, an island separated by deep water, than it does to that of 

 Halmahera, an island connected by strings of islets which are separated from each 

 other by only shallow straits. It would seem at first that this condition might 

 be accounted for either upon the ground that we did not know Halmahera 

 sufficiently well, or that these species have reached Mysol by accidental carriage. 

 But, first, I can not believe that, if the forms existed on Halmahera, now so well 

 known, they would not have been found long ere this, and secondly, if we had to 

 account for the occiu-rence of only one or two species on Mysol, we might expect 

 accidental carriage to be responsible, but this is not likely to be the case where 

 we have a considerable number of species to account for upon an island which, 



' Species marked with an asteripk reach here the extreme eastern limit of their range (five out of 

 eighteen or nearly twenty per cent).
