Var. LIOLEPIS. 
Bedriaga (Arch. f. Naturg. 1879, p. 292) has briefly alluded to a small form which 
he observed alive at Valencia, on the road to the Dehesa de la Albufera, and which 
struck him as remarkable for the extremely small dorsal scales and smooth caudal 
scales, the middle dorsals of which are more or less enlarged. ‘The colour is described 
as a pale yellowish brown above, with a brown, white-edged lateral band, greyish or 
yellowish beneath. Length from snout to vent 49 millimetres. 
Among numerous specimens from Valencia in the British Museum (Lilford, Bosca, 
Bolivar) some agree with Bedriaga’s description in having the upper caudal scales very 
faintly keeled, almost smooth, and the granular dorsal scales are very minute, scarcely 
larger than those on the upper surface of the tibia. Some specimens, however, have the 
dorsal scales larger, and the caudal scales distinctly, though rather feebly, keeled; | 
do not think it possible to sharply define this form, which may be said to connect the 
typical form with the var. hispanica, and also with the var. pityusenis. I have received 
specimens of the same form from Seville (Prof. Calderon). 
The scales across the body vary from 52 to 69; 3 or 4 correspond to one ventral 
plate, and 42 to 56 to the length of the head; they are smooth or faintly keeled on 
the back ; ventral plates in 6 longitudinal rows, except in one 2, which has 8; collar- 
plates usually smaller than in the typical form, 9 to 14 in number; 25 to 35 gular 
scales and granules on the median line. Upper caudal scales feebly or faintly keeled, 
sometimes nearly smooth ; 28 to 34 scales in the 4th or 5th whorl behind the postanal 
granules. Femoral pores 15 to 22 on each side. 23 to 27 scales under the fourth toe. 
Nearly constantly four anterior upper labials!. Masseteric disk more or less 
* One specimen has five on one side.
