"Color in alcohol. — Above drab gray; a seal 

 brown stripe originating behind the nostril, con- 

 tinuing on the lores, passing well above the 

 ear-opening and widening above the shoulder as 

 an enlarged blotch ; behind this blotch a fainter 

 continuation of the lateral stripe which becomes 

 very irregular posteriorly and fades out on the 

 sides of the tail ; six or seven very narrow dorsal 

 bars between these lateral stripes, the anterior 

 interrupted in the middle and ending as a for- 

 ward-curving blotch on each side of the nape, 

 the remaining bars somewhat similar in shape 

 but paler; a faint irregular roundish marking on 

 the occipital region ; traces of wavy crossbars on 

 the upper limb surfaces; upper and lower lips 

 minutely spotted with pale dots; lower surfaces immaculate pale olive 

 buff darkening slightly below the tail. 



"Paratypes. — M.C.Z. 25425 from Pte. a Raquettes, Gonave Island, 

 collected in 1927 by W. J. Eyerdam, is similar to the type in propor- 

 tions and generally in coloration, although the pattern of dorsal 

 crossbars is stronger than in the type specimen, and the entire body 

 is darker in hue. The upper and lower labials are dark, and the lower 

 surface of the body is heavily powdered with gray dots. This para-
