One of the Lizards was also regarded by Mr. Gray as forming a 

 new genus in the family of Geckos, which he characterized as Ibl- 

 lows, under the name of 



DiPLODACTYLUS. 



Sąuama; subconformes, minutae, Iseves, abdominales paulo nia- 

 jores, caudales majores annulatae, labiales mediocres distinctae, 

 tribus anterioribus utrinque muito majoribus, gulares nulL-e, Cauda 

 cylindrica, ventricosa. Digiti 6, 5, simplices, subasquales, subcy- 

 lindrici, apicibus subdilatatis, subtus bifidis, discis duobus carnosis 

 laevibus ovalibus obliquis ; unguibus 5, 5, parvis, maxime retracti- 

 libus. Porijemorales nulli. 



This genus differs from Phyllodactylus, Gray, in the under sides 

 of the tips of the toes being furnished with two rather large oblong 

 tubercles, which are truncated at the tip, and form two ovaI disks 

 placed Gbliquely, one on each side of the clavv, instead of having, 

 as in Phyllodactylus, two membranaceous scales. The scales of the 

 body are also uniform, while in that genus there is a series of larger 

 scales extending along the back. The species, a dravving of which 

 was exhibited, was named 



DiPLODACTYLUS viTTATUs. DipL Jtiscus, vitlu dorsūU loJlgitU' 

 nali latu saturatiore ; laterihus testaceis, artubus, caudaque ma- 

 culis seriatisjlavis marginatis. 



Hab. in Nova Hollandia. 



The length of the head and body is 2 inches ; that of the tail \\ 

 itich. On each side of the body there are tHO ron's of rather distant 

 small spots, which become larger on the uppcr surface of the tail ; 

 they are scattered on the iimbs. 



The other Reptile described was a species of Tiligua, the 



TiLiauA CuNNiNGHAMi. TU. sguamis superioribus carinato- 

 spinosis^ carinis serialis. 



Hab. in Nova Hollandia Orientali extratropicS. 



This species is very distinct from all the rast of its genus, and 

 even of its family, on account of its carinated scales, vvhich are suf- 

 ficiently prominent on the back and sides, but become more so oni 

 the Iimbs, and still larger in size, although their series decrease in] 

 number, asthey approach the extremity of the tail. The colour is' 

 pale brown, dotted vvith yellon' above, and paler beneath, with ob- 

 scure darker spots. The head and body measure 8, and the tail 

 7, making a totai length of 15 inches. 



Mr. Cunningham found this Lizard in a torpid statė in a barren 

 sandy partof the scrubby country in Jat. 29°, while prosecuting his 

 overland journey from Port Jackson tovvards Moreton Bay in the 

 winter of 1827. 



Mr. Gray stated that the comparison of a young specimen of 

 Mus giganteus, Hardw., with a specimen of Alus setifer, Horsf., 

 presented to the British Museum by their respective describers, had 

 enabled him to correct an opinion expressed by M. Temminck in 

 the 'Tableau Mėthodicjue,' appended to his ' Monographies de Mam-
