Gonyocephalus dilophus (Dumeril et Bibron). 



DuMERiL ET Bibron, Erpet. gen., 1837, 4, p. 419, pi. 46. Boulbngeb, Cat. lizards Brit, mus., 1885, 1, 

 p. 290. 



Type locality: — New Guinea. 



A fine adult of this remarkable species collected by Mr. A. E. Pratt in the 

 Aru Islands is in the Museum series. 



Gonyocephalus modestus Meter. 

 Meyer, Mon. Berl. akad., 1874, p. 130. Boulenger, Cat. lizards Brit, mus., 1885, 1, p. 294. 



Type locality: — Jobi Island. 



Of the two examples examined, one came from Pom, Jobi Island, Papua; 

 the other was purchased abroad, and comes from the Astrolabe Bay, German 

 New Guinea. They are both of practically the same adult size, some 300 mm. 

 in length; but the serration on the dorsal aspect of the tail is much more pro- 

 nounced in the specimen last mentioned than in the other. 



Calotes cristatellus (Kuhl). 

 KuHL, Beitr. zool. und vergl. anat., 1820, p. 108. Boulenger, Cat. lizards Brit, mus., 1885, 1, p. 316. 



Type locality: — unknown. 



Bryant took one at Buitenzorg, and there were six in my collection from near 

 Garut, Java. This may be known as C. cristatellus cristatellus (Kuhl) . 



Other examples — six from Ternate, one from Ceram, and four from Hal- 

 mahera — often vary considerably from the condition seen in the Javan specimen. 

 Javan examples can be matched in the Moluccas, but only rarely. Boulenger 

 has noted the differences which may occur (loc. cit., p. 317). Moluccan examples 

 probably represent a valid geographic race, and may be known as Calotes cris- 

 tatellus moluccanus Peters, (Mon. Berl. akad., 1867, p. 171). 



The Celebes examples should probably stand as Calotes cristatellus celebensis 

 Giinther (Proc. Zool. soc. London, 1873, p. 168). 



Calotes mystaceus (Dumeril et Bibron). 

 Dumeril et Bibron, Erpet. gen., 1837, 4, p. 408. Boulenger, Cat. lizards Brit, mus., 1885, 1, p. 325. 



Type locality: — Burma. 



This' species was seen commonly on fences and in garden shrubbery at 

 several places in Upper Burma. Four from Mandalay were preserved.
