the male; length of pileus 2 to 2^ times its width. Neck at least as 

 broad as head. Hiud limb reaching the shoulder or the collar in the 

 male, the elbow or the axil in the female ; foot as long as the head 

 in the male, a little longer in the female ; toes comparatively short. 

 Tail cylindrical, flattened at the base, about twice as long as head and 

 body. 



Nostril between the nasal, two postnasals,* and the first upper 

 labial, the rostral being always excluded. Nasals usually in contact 

 with each other, the median suture often very short ; exceptionally t 

 the rostral forms a more or less extensive suture with the frontonasal, 

 which is usually at least as long as broad, but sometimes considerably 

 broader than long ; suture l)etween the prefrontals often very short ; 

 an azygos shield rarely present between the prefrontals, j 



Frontal 1\ to If times as long as broad, as long as its distance from 

 the rostral or from the end of the snout, narrower, behind, than the 

 principal supraoculars, often § in contact Avith the first supraocular or 

 the several small shields or granules in which it may be disintegrated. 

 Parietals 1\ (young) to If times as long as broad, usually not in 

 contact with upper postocular.jl Occipital always shorter than the 

 interparietal and usvially broader, sometimes much broader. The two 

 major supraoculars, which are equal in length or the first slightly the 

 longer, separated from the superciliaries by a complete series of granules, 

 sometimes by two ; the fourth supraocular usually in contact -with the 

 upper temporal. 6 to 8, rarely 9 superciliaries, the suture between 

 them all vertical or nearly so. Two superposed postnasals ; two loreals, 

 first shorter than second. Usually 5, sometimes 6, rarely 4,^ upper 

 labials anterior to the subocular, the lower border of Avhich is as long 

 as the vipper, or a little shorter. Temporal region with small granular 

 scales ; masseteric shield large or small, sometimes absent ** ; tympanic 

 present ; a large supratemporal, well visible from above, usually 

 followed by one, two, or three smaller shields. 



No pterygoid teeth in the specimens examined. ft 



* I have come across but one exception, a male fi-om Lissa, in which the 

 postnasal is single on the right side. 



+ In one specimen from Curzola and in two from Brestica. 



X In one specimen from Dalmatia (Bedriaga Collection)!, and in one from 

 Curzola. 



§ In 17 cases out of 32. 



II In 48 cases out of 64. 



T 5 labials in 47 cases, 6 in 12, 4 in 5. 



** Large in 32 cases, small in 22, absent in 10. 



ft Siebenrock (Sitzb. Ak. Wien, ciii, i, 1894, p. 294) says they are sometimes
