HORN EXPEDITION—REPTILIA. 
Localities. —Adniinga, Dalliousie. 
The remarkable feature of these specimens is that there are, in addition to the 
two pra?anal pores, two femoral pores, one on each limb. 
This character will involve a modification in the definition of the genus. 
Apart from the presence of these pores, T. tetraporophora serves to connect 
the two previously described species of the genus. 
We allow the above to remain as published in the P.R.S.V., Dec., 1894. We 
have since received an extensive series of Tympanocryptis., collected by Professor 
Spencer in the same district in February, 1895, during the breeding season. In 
this collection are several examples of T. Imeata^ both male and female, with two 
pneanal and two femoral pores as well as many others agreeing with our 7\ tetra- 
porophora., which was mainly distinguished from T. cephalus by the presence of 
femoral pores. After considering these additional facts we feel compelled to go 
further in the union of these forms and to regard them as varieties of one species, 
T. lineata. We now give particulars of the forms. Out of eight specimens for 
instance :— 
iyi) Two typical T. lineata (<? and ?) with two pneanal and two 
femoral pores. 
ip) Two (c? and $) with faint indication of the longitudinal light lines 
and dark spots, both with two pneanal and two femoral pores. 
(c) Four (two d' and two $) uniform reddish-brown, each with two 
prmaiial and two femoral pores. 
The definition of the genus will then stand thus :— 
Tympanocryptis, Peters. 
Tympanum hidden. Body depressed, covered above with heterogeneous 
scales. No dorsal crest. N(j gular sac; a strong transverse gular fold. Tail 
round. A prseanal and a femoral pore on each side, sometimes absent. 
Habits .—Grround lizards, usually met with under logs and stones. 
Mode of reproduction .—Nine to twelve eggs laid in February or March. 
Diporophora, Gray, 
(9) Diporophora winneckei., L. and F. (Plate XI., Fig. 5). 
Description .—Habit slender; head rather narrow, with distinct canthus 
rostralis; covered above with sub-equal keeled scales ; nostril equally distant from
