MEXICAN SNAKES AND CROCODILIANS SMITH 457 



accumulated in the axils of dead palm trees. They would occasionally 

 flatten the head and fore part of the body when discovered. 



Variation in cephalic scutellation of this series is extensive. Supra- 

 labials 6-7 in one (sixth and seventh fused), 7-8 in four, 7-7 in 48; 

 infralabials 5-6 in one, 5-7 in one, 6-7 in four, 7-8 in two, 7-7 in 

 forty-five ; postoculars 3-3 in two, 2-3 in two, one or both fused with 

 supraocular in four, 1-1 in two, 1-2 in two, 2-2 in forty-one; a pre- 

 subocular (sometimes double, always minute) on one or both sides in 

 sixteen ; a small preocular split off corner of prefrontal in two. Twenty 

 specimens are uniform red above, with no evidence of black cross bars 

 (except that following light nuchal collar) ; in four others there are one 

 or two small black spots on the body ; other specimens represent inter- 

 mediate conditions between this and the strongly barred phase repre- 

 sented by the majority of the remaining specimens.
