griffin: ophidia from south America in carnegie museum 



191 



specimen is dry, the scales appear brownish with an iridescent sheen. The scales 

 of the upper surface of the head are similarly light brown or olive with dark margins. 

 The upper labials are white. The lower surface is either entirely white, or some of 

 the gastrosteges have more or less complete black anterior margins. Nos. 7 and 

 113, young specimens, are as uniformly marked as the older ones. There is no 

 nuchal collar, nor are any transverse bars visible. The length of the tail of these 

 specimens is contained 6| to 7 times in the total length. The number of gastrosteges 

 and urosteges varies within very narrow limits and about the minimum for L. 

 poecilogyrus. It is possible that the specimens represent a well defined subspecies. 

 I feel doubtful about the identification of No. 111. No pits are visible on the 

 scales, and the length of the tail is contained six and one-half times in the total 

 length. The dorsal scales are mostly black, but some are white, or white-edged, 

 so arranged as to form numerous narrow light cross-bars or reticulations. Most 

 of the gastrosteges are entirely or partly brown.
