THE HERPETOLOGY OF HISPANIOLA 303 



labials are two scales (post-geneials) lying in a transverse row; 217 

 rings on the body and 21 on the tail; the segments of each ring longer 

 than broad, excepting the two median ventral ones which are slightly 

 broader than long and between which the suture is less deep than else- 

 where; 14 segments above the lateral line and 20 below it; six anal 

 shields; four preanal pores. 



''Color {in alcohol). — Drab above, the center of each segment darker; 

 lighter below anteriorly, turning to yellowish-white posteriorly. 



''Dimensions. — Head and body length, 137 mm.; tail, 12 mm.; 

 greatest diameter of body, 5 mm. 



"Variations. — A single paratype, taken at the same time and place 

 as the type, besides being somewhat larger, varies from it in the fol- 

 lowing slight characteristics: The temporal scale is relatively some- 

 what smaller than in the type specimen; there are 18 segments below 

 the lateral line instead of 20; there are 20 tail-rings instead of 21. In 

 all other respects it agrees with the type specimen. 



"The length of the head and body in the paratype is 170 mm.; tail, 

 17 mm.; the greatest body diameter about 6 mm.; the body is some- 

 what shrunken and stiffened. 



"Remarks. — From the true Amphisbaena innocens, its closest rela- 

 tive, it differs in having 20 to 21 tail rings instead of 13 to 16; in hav- 

 ing the first and third supralabials proportionately smaller in relation 

 to the second supralabial, and in having a somewhat shorter post- 

 mental."

Original description. — "Diagnostic Characters. — A slim, short- 

 legged species having ten stripes of dark brown extending the length 

 of the body; supranasals in contact behind the rostral; two pairs of 

 nuchals; when the limbs are pressed along the side of the body, 

 the appendages fail to meet by a distance greater than or equal to 

 the length of the hind limbs.
