Synopsis of the South African Species. 



I. A series of white enlarged conical granules forms a gulo- 

 ventral crest from chin to vent ; body uniformly granulate ; 

 movable dermal lobes behind the occiput. 

 Occipital lobes small, just meeting behind the occiput . . . . C. quilensis. 

 Occipital lobes large, in contact on the median line in the 

 adult C. dilciyis. 



II. A gular crest, no ventral crest ; no occipital lobes ; granules 

 of body intermixed with enlarged tubercles. 



A. Gular crest formed of conical or compressed pointed 

 tubercles, not covered with scales or granules. 



Tubercles of gular crest conical ; scales on tail nearly uniform 



granules C.melanocephalus. 



Tubercles of gular crest long, thin, compressed C. gutturalis. 



B. The anterior tubercles or lobes of the gular crest covered 

 with granular scales. 



1. Tail not longer than head and body, often shorter. 

 Gular crest formed of small, subconical lobules ; tail shorter 



than head and body C. tccniobronchiis. 



Gular crest formed of compressed lobes, all longer than broad 

 and not overlapping ; tail as long as or a little shorter than 



head and body C.pumilus. 



Gular crest formed of compressed lobes, the anterior very 

 large and overlapping or disposed in an alternating series ; 

 tail considerably shorter than head and body C. ventralis. 



2. Tail considerably longer than head and body in the 

 males ; anterior lobes of gular crest at least as broad 

 as long. 



Dorsal crest a serrated ridge C. damaranus. 



Dorsal crest formed of 14 or 15 very large conical tubercles . . C. caffer. 



III. Neither gular nor ventral crest ; body uniformly granu- 

 late ; a series of isolated, knob-like, very large tubercles 



along the spine C. namaquensis.
