376 Lacerfidie. 



smooth. Digits compressed, with smooth scales beneath, 

 denticulated laterally. No femoral pores. Tail long, 

 cylindrical. 



A single species. 



This genus is to l)e regarded as an exaggerated form of the repre- 

 sentatives of the section Saurites in the genus Scaidira, from which 

 it is evidently derived, as Macinakonia is derived from ScaiMra, s. str. ; 

 l)ut the generic differentiation is greater tlian in Macmahonia, for, in 

 addition to the loss of the femoral pores, the collar has disappeared, 

 and the head has assumed an extraordinary shape.

Head large, 3| times in length to vent. Rostral much depressed, 

 forming with the first seven upper labials the projecting border of the 

 snout ; nasals in contact behind the rostral ; frontonasal a little 

 broader than long; prefrontals forming a median suture; frontal 

 narrow, shorter than its distance from the end of the snout ; parietals 

 neai-ly twice as broad as long, separated from each other by the inter- 

 parietal, which is smaller than the frontoparietals. Three large 

 supraoculars, the first with a small detached shield on the inner side. 

 Lower nasal not reaching the rostral, resting on the first and second 

 upper labials ; anterior loreal larger than the second ; subocular resting 

 on the 5th to 7tli upper labials ; temporal scales granulai' ; ear-opening 

 narrow, without marginal denticulatiou. 



6 pairs of chin-shields, the three anterior in contact in the middle; 

 gular scales very small, granular. 



Scales extremely small, granular, larger on the lower part of the 

 sides and passing gradually into the ventral jjl^^tes, which are small, 

 square, and number 20 to 24 in a transverse series. Preanal scales 

 numerous, small, sul)equal. 



Scales on the flattened base of the tail similar to the dorsals, those 

 on the rounded portion elongate quadrangular and feebly keeled. 



The type is described as golden yellow above, with a wide-meshed 

 black network on the back and limbs ; a black vertebral streak ; head
