Aporophis lineatus (L.). 



A colour-variety of this snake, which is to be fonnd in 

 the maiseum nnder the nnmber 834, will be mentioned below. 

 The lateral dark lines are remarkably broad, nearly as broad 

 as the vertebral band and occnpying the fonrth, half the third, 

 and half the tifth outer rows of scales. They are darker 

 than the vertebral band, but the inner margin is lighter 

 tlian the outer and the middle parts. In the normal states 

 of things the lateral lines are very narrow, occnpying only 

 the median parts of the fonrth outer row of scales. The 

 specimen, having also a fewer number of subcaudals than 

 stated in Boulenger's Cat. of Önakes, 67 pairs instead of 

 79 — 93, is from Uruguay, obtained by Mr. Åberg in 1886. 



1 Possibly a little mutilated.
