THE ELEGA2^T OPIIIOPS. 40 



Unlike the scaly Lizard, this species lays its eggs in a convenient spot and tlien leaves 

 them to be hatched by the warm sunbeams. Sandy banks with a southern aspect are the 

 favored resorts of this reptile, which scoops out certain shallow pits in the sand, deposits her 

 eggs, covers them up, and then leaves them to their fate. Mr. Bell, who has paid great 

 attention to this subject, has remarked that the eggs are probably laid for a considerable 

 period befoi'e the young are hatched from them. 



As has been already remarked, the coloring of this creature is exceedingly variable in 

 different individuals. Generally it is sandy-brown above, with some faint bands of a darker 

 brown with rows of black spots, which sometimes have a whitish dot in their centre. The 

 sides have a tinge of green more or less distinct, and the under surface is white. In some 

 individuals the green is very distinct. The average length of the Sand Lizard is about seven 

 inches or a little more. 



Passing by a series of genera affording but few interesting points, we come to the curious 

 animal called the Cape Spine-foot. The generic name Acanthodactylus, signifies Thorn, or 

 Spine-toed, and is very appropriately given to this animal and the other species of the same 

 genus. All the Spine-foot Lizards are inhabitants of Africa, and most of them are found 

 towards the northern poi-tion of that continent. 



According to Dr. Smith, "tliis Lizard is found on the sandy districts of Great Namaqua- 

 land, and where the surface of the country is irregular it is generally met on the highest spots. 

 Where small sand-hills occur, it resorts to them in preference to the other localities, and from 

 the peculiar assistance it derives from the serrated fringes which edge its toes, it runs over the 

 loose sand on the steep sui-faces of those slopes with great activity. It feeds on insects." 



The color of this Lizard is a very peculiar brown above, changing from yellow-brown to a 

 much warmer hue, partaking of the orange. The top of the head is mottled with dark brown, 

 and the back is freckled with the same hue. From the eyes run two whitish bands on each 

 side, the lower terminating at the hind-leg and the upper reaching some distance along the 

 tail. Between and about these bands are bold brown mottlings in the male, and an orange 

 wash in the female. Tlie upper part of the legs are also mottled with dark brown. The toes 

 are very long, especially those of the hind-foot, and are edged with a fringe composed of 

 sharply pointed scales. The female is larger and more clumsily made than the male. 



Another pretty species of Lizard, termed the Namaqua Ekemias, is found the portion of 

 Africa from which it derives its name. The name Eremias signifies a dweller in a wilderness, 

 and is given to this and several other species because it is always found in hot and arid situa- 

 tions, the sandy flats between Cape Town and Little Namaqua-land being its most favored 

 localities. 



It is chiefly remarkable for the great length and slendemess of its tail, which measures 

 five and a half inches in length, although the head and body together are only two inches long. 

 The color of the back and upper pai"ts is delicate brown mottled with a deeper hue, and along 

 the back are drawn four narrow lines of light reddish orange. The sides are cream-yeUow, 

 the upper portions of the legs are olive-brown, and the under surface of the animal is yellow- 

 ish-white. There is a trifling variation in the coloring, according to the age of the individual. 

 Thirteen or fourteen species of this genus are known to zoologists, most of them being natives 

 of Africa. 



OuE last example of the true Lizards or Lacertinidfe is the curious little creature termed 

 the Elegant Ophiops. Two species are knovra as belonging to this genus, and they can at 

 once be separated from the true Lizards by the character of the eyelids, which are only rudi- 

 mentary and hardly visible, so as to have gained for their owners the generic title of Opliiops, 

 or Serpent-eyed Lizards. 



The Elegant Ophiops inhabits the south-eastern portions of Europe, and the neighboring 

 parts of Asia. The shores of the Mediterranean ap]iear to be favorite localities of the Ophiops, 

 and in those places it is not at all uncommon. It is lively and active in character, and, like
