Lepidosis Rostral. — Touches 6 shields ; the rostro-nasal sutures 

 largest, about twice the rostro-internasal. Internasals. — A pairs; 

 the suture between them half, or less than half that between the 

 prsefrontal fellows, about two-thirds the internaso-prsefrontal 

 sutures. Prcefrontals. — A pair; the suture between them rather 

 greater than the prsefronto-frontal ; in contact with internasal, 

 postnasal, loreal, prteocular, and sometimes with the supraocular. 

 Frontal. — Touches 6 shields usually, 8 when the prgeocular 

 meets it ; the fronto-supraocular sutures largest. — Supraoculars. — 

 As long as frontal, but not so broad in a line connecting the 

 centres of the eyes. Nasals. — Two, almost entirely separated by, 

 the nostril, a suture running to the 1st supralabial. Loreals. — One 

 rather longer than deep. Troeoculars — .One. Postoculars. — Two. 

 Temporals. — Two, the upper touching a supralabial usually the 6th 

 or 7th. Supfralahcals. — Very variable, 9, 10 or 11; usually two touch 

 the eye, the 5th and 6th most constantlj^, sometimes the 6th and 

 7th, or in some examples three touch the eye. Infralahails. — 6. 

 The 5th and 6th touch the posterior sublinguals ; the 6th is the 

 longest and in contact with three scales behind. Suhlinguals. — 

 Two pairs, subequalor the anterior rather longer. Gostals. — Subject 

 to much variation. Inmidbody they maybe 25 to 29. Anterior-
