Distribution. —Peak Downs, Queensland (B.M.C.); (Luijilioltz). 
(2) Nephrunis Icevis, De Vis. Native name Illchiljera. 
All the smooth individuals belonging to the Nephrurus hitherto obtained 
from this district have been described under the name of N. platyurus, Blgr. The 
specimens collected by this Expedition, although subject to variation, evidently 
all belong to one species. We have compared them with a typical specimen 
of IV. Icevis., De Vis, supplied by Mr. De Vis to the Macleay Museum, Sydney, 
from Thai’gomindah, Queensland. The result of our examination has been to 
identify the Central Australian form with that from Queensland, and we there¬ 
fore propose to unite N. platyurus with N. Icevis, the latter name having the claim 
of priority. 
The characters by which the species are distinguished* are — 
(i.) In N. hevis the tail nearly as long as the fore-limb, as long as the 
head ; in N. platytcrus the tail a little longer than the fore-limb, 
longer than the head. 
(ii.) In W Icevis the limbs rather short; in JV. platyurus limbs long, 
slender. 
(iii.) In N. platyurus there are only four tubercles across the middle of 
the interorbital space. 
(iv.) In N. Icevis the number of labials twenty on each side above and 
below ; in N. platyurus seventeen. 
(v.) In N. platyurtis there are eighteen distinct transverse grooves on 
the upper and lateral surfaces of the tail. 
The variation in characters (i.), (ii.) and (iv.) will be best illustrated by means 
of a compai’ative table of measurements and enumeration.
