Mental broad. Ear entirely hidden. Olive-colored above, with indistinet black lines along the series of 

 scales. Sides blackish, tbis color being sharply defined towards the back. Abdomen dotted with black; 

 lower part of the tail pure yellowish-white. 



Peak Downs. The bärgest of several speeimens is 113 mm. long, the tail measuring 55 mm. 



NEPHKUBUS (g. n. Geckot). 



Upper parts fmely granulär, with round groups of conical tubercles, the one in the centre being 

 the largest. Toes not dilated, cylindrical, of moderate length, each armed with a non-retractile claw, 

 granulär at their lower surface. Pupil vertical. Upper eyelid separated by a fold from the skin of the 

 head, with prominent margin; lower eyelid indicated by a distinet fold. Tail extremely short and small, 

 swollen in its proximal, and thin and tapering in its distal half, the extremity terminating in a globular, 

 kidney-shaped knob. 



Nephrurus asper. 



Head large and depressed; eyes large; opening of the ear a vertical slit, with the tympanum 

 deeply sunk. All the upper and lateral parts, with the exception of the upper side of the head, are 

 densely covered with the groups of tubercles mentioned above, which, although smaller extend also over 

 ihr throat, the outer sides of the belly, and the lower parts of the upper arm on the thigh. On the upper 

 surface of the swollen portion of the tail they are arranged in four longitudinal series. The middle of the 

 abdomen and the terminal knob are covered with minute smooth granules. Upper and lower labials low, 

 numerous. Legs slender. Brownish above, with many of the tubercles white; faint indications of narrow 

 whitish transverse lines; head with a widemeshed net-work of blackish lines. Lower parts whitish. 



I have known this Singular Lizard for many years from photographs sent to nie by Mr. Krefft; 

 the speeimens were from the Burdekin River, but as they were the property of the Trustees ofthe Sydney 

 Museum, I had no opportunity of describing the species, until Hr. Dämel brought examples from Peak 

 Downs. The speeimen before nie is 110 mm. long, the head (to the ear-opening) measuring 28 mm., and 

 the tail 22 mm. 



Hoplocephalus damelii. 



Scales in seventeen rows. In geueral habit similar to a Coronella leevis. Head depressed, oblong, 

 scarcely distinet from neck. Anterior frontals very small, only about one fourth the size of posterior. 

 Vertical five-sided, longer than broad, with a right angle behind. Occipitals of moderate length rounded 

 behind; two postoculars; the Single praeocular just reaching the upper surface of the head. Six upper 

 labials. Temporais 2 4- 3 -f 3: only one is in contact with the postoculars; those of the second and 

 thii-d row small, scalelike. Each occipital is laterally in contact with four scales. Ventrais 171; 

 subcaudals 43. 



Upper parts uniform olive-brown, lower pure white; in some of the speeimens, especially younger 

 ones. the head and neck are somewhat darker than the rest ofthe body. 



Several speeimens were obtained by Hr. Dämel, after whom I have named this species, at 

 Elockhamptoii and Peak Downs. The largest is 15 inches long, the tail measuring 2Vs inches. 



Hoplocephalus maculatus (Steindachner). 



Demsonia ornata (Erefft) is based on a speeimen of this species which was accidentally provided 

 with a separate shield in the loreal region.
