olive, with six black longitudinal bands, of which, however, 

 two or more may be indistinct or disappear altogether. The 



bands of the middle pair are separated by the three median 

 dorsal series of scales, narrow, and frequently absent. The 

 upper lateral band commences from the lower postocular, and 

 passes behind into a broad band, bordering the subcaudals. 

 The lower lateral band runs along the edge of the abdomen, 

 and is sometimes narrow, sometimes broader. Lower parts 

 whitish, with more or less numerous blackish spots, the spots 

 being much more developed in the female than in the male. 



Three specimens from Eastern Betsileo, the largest 24 inches 

 long, the tail measuring 65 inches. 



Dromicus macrocercus. 



Extremely similar to D. sexUneatus^ but much more elon- 

 gate and slender. Scales in seventeen rows ; ventrals 156, 

 156, 159; anal bitid; subcaudals 153, 139, 152. Head 

 rather small, eye of moderate size ; vertical not quite so long 

 as occipital ; loreal square ; one pre- and two postoculars. 

 Eight upper labials, tlie fourth and fifth entering the orbit j 

 temporals 1 + 2 + 3, the anterior in contact with the lower 

 postocular only. JJentition diacrantherian. The coloration 

 is the same as in D. sexlineatus, with the exception that the 

 two median dorsal bands are scarcely indicated. 



Three specimens from Eastern Betsileo, the largest being 

 42 inches long, the tail alone measuring 2H inches. 



Taclnjmen is infralineatus. 



Scales smooth, in nineteen series, those of the vertebral 

 series not enlarged. Ventrals 186 ; anal entire ; subcaudals 

 62. Head moderately broad, depressed ; loreal subtriangular, 

 as high as long ; one preocular, extending onto the upper- 

 side of the head, but not reaching the vertical. Two post- 

 oculars. Seven up]ier labials, the third and fourtli entering 

 the orbit; temporals 1 + 2 + 3, the anterior in contact with
