86 Dr. A. Griinther on some Ceylonese 



Nessia Thwaitesn. 



Toes four in front and four behind. Nostril close to the 

 hind margin of the rostral shield^ and xoithout longitudinal slit 

 behind. 



This species might be taken for a Sepoid, in consequence 

 of the situation of the nostril, which is in contact with the 

 hinder edge of the rostral shield. However no other shield 

 enters into the circumference of the nostril, which is entirely 

 within the rostral. Otherwise the pholidosis of the head is 

 verj similar to that of the other two species known. Two 

 loreals, one behind the other. Trunk surrounded bv twenty- 

 six longitudinal, and seventy-two transverse series of scales. 

 Prajanals and subcaudals like the other scales. Limbs rather 

 more developed than in N. Burtonii ; the hind leg nearly as 

 long as the head. All the toes distinct and clawed ; the an- 

 terior very short ; the first of the posterior shorter than the 

 second, the second shorter than the third and fourth, which 

 are nearly equal in length. Ear-openings minute, hidden. 

 Upper parts brown, the lower of a lighter colour. 



One specimen 4 inches long; tail I3 inch. 



Calotes liocephalus. 



No spines whatever on the side of the head. Dorsal crest 

 composed of slender spines of moderate length on the neck, a 

 low, merely serrated crest in the middle of the trunk, but re- 

 appearing in the sacral region as a short series of three or four 

 spines. A very distinct fold in front of the shoulder^ covered 

 by granular scales. Gular sac very slightly developed. 

 About forty-five series of scales round the middle of the trunk. 

 Scales round the part of the tail in which the penis is hidden 

 much the largest. Green, with irregular dark cross bands on 

 the back. Upperside of the head marbled with dark green. 

 A narrow green band from the eye to above the tympanum. 

 Tail olive, with broad brown rings. Limbs with alternate 

 lighter and darker green rings. 



One adult male is 15 inches long, the tail being 11 inches. 



Hemidactylus Coctcei. 

 Ceylonese specimens are not specifically distinct from those 

 of the continent, as has been ascertained also by Cantor (see 

 Kelaart, Prodr. Faun. Zeyl. i. p. 160). Examples occur in 

 which the ornamental colours are unusually dark, in the form 

 of clouded transverse bands. 



Gymnodactylus frenatus. 

 The coloration of the young is extremely similar to that of 

 Euhlejpharis Hardwickii,
