COPHOTIS. 131 



measuring 7. In young specimens, the trunk of which is only 1 inch long, the rostral 

 appendage is already very distinct; in its internal structure it is spongy, and apparently 

 consists of an erectile tissue. 



Ceratophoea aspeea. (Plate XIII. figs. G, G'.) 



Head covered vdth very small, irregular shields, each of which is elevated into a small 

 tubercle ; a larger tubercle behind the superciliary edge, and another on each side of the 

 occiput ; occiput with a pair of low ridges, convergent anteriorly. Nasal appendage cylin- 

 drical, slender, covered with small, imbricate, strongly keeled scales ; it is nearly half as long 

 as the head in the male, but quite rudimentary in the female. Labial shields numerous ; 

 throat vdth small, strongly keeled scales, without appendage ; no fold in front of the shoulder. 

 Nostril small, lateral. Scales on the back and sides very small, with numerous, irregularly 

 scattered, larger keeled scales ; no crest whatever, but some of the larger scales form short 

 angular series across the vertebral line, with their angles pointing backwards. Ventral 

 scales strongly keeled ; prceanal region covered with very small scales. Tail of moderate 

 length, not compressed, mth all its scales keeled ; those at its lower surface are scarcely 

 longer than broad. Limbs rather long, the hind limbs extending to, or nearly to, the orbit, 

 if laid forwards. Brownish, marbled with darker; a rhombic light-coloured spot on the 

 sacral region. The brown spots on the fore leg are edged with white in the male. 



I have examined a male and female of this extraordinary species, both apparently matui'e, 

 but not longer than 3 mches, of which the tail measures one-half. The British Museum 

 received them from Ceylon, from the same source as the C. stoddartii and C. tennentii ; hence 

 it is probable that it is also confined to the mountainous parts of the interior of the island. 



Figure G of Plate XIIL represents the female in a position which we have observed in 

 many Agames ; figure G' the head of the male. 



COPHOTIS, Peters. 



Tympanum hidden. Back and sides covered with very large, imbricate, 

 irregular scales subequal in size. A nuchal and dorsal crest. A small 

 gular sac in both sexes. Male with only a very small tubercle behind the 

 rostral shield. 



Only one species is known, from Ceylon.
