so; the fourth whorl ])ehmd the postanal small scales contains 29 

 scales. 



• Back spotted ail over ; sides darker, with whitish ocellar spots ; 

 iipper surface of head unspotted ; labials black- edged ; uniform 

 white beneath. 



> 2. Female. — Head as in the preceding specimen, but smaller and 

 less strongly depressed, its gi-eatest depth equalling the distance 

 between the centre of the eye and the tympanum. Rostral as in 

 the preceding, but separated fi-om the frontonasal, the nasals 

 forming a short median suture; frontal, supraciliary graiuxles, 

 and parietals as in the preceding ; foui-th supraocular undivided ; 

 occipital very short, a little narrower than the interparietal, and 

 separated from it by an additional shield ; masseteric shield sepa- 

 rated from the upper tempoiul shield by a single series of granules ; 

 iive anterior upper labials ; subocular as in the preceding. 



Collar even-edged, composed of 9 plates ; 25 scales between 

 the chin-shields and the collar. 



Body much depressed. Dorsal scales oval and distinctly keeled ; 

 51 scales across the middle of the body, 3 corresponding to a 

 ventral plate, 35 to the length of the head. Ventral plates in 

 6 longitudinal and 27 transverse series. Anal plate preceded by 

 a large but nai'rower plate and bordered on each side by 3 small 

 plates. 



Hind limb reaching the axil. Scales on upper surface of tibia 

 rhomboidal and strongly keeled, much lai-ger than the dorsals, 6 

 of the former corresponding to 10 of the latter. Femoral pores 

 18-18. 25 scales under the fourth toe. 



Upper caudal scales very strongly keeled, those on the sides 

 raised, subtrigonal, almost spinose, truncate behind ; the whorls 

 alternately longer and shorter, and the scales of the two median 

 dorsal series of every other whorl much wider than the others ; 

 28 scales in the fourth whorl. 



The black spots form two irregular series along the middle of 

 the back ; a dorso-lateral series of white black-edged ocelli ; a 

 large ocellus above the shoulder ; black dots on the head ; the 

 labials black-edged ; lower parts uniform white. 



3. Gravid female* . — Head very small and even rather more de- 

 pressed than in specimen No. 1, its greatest depth hardly equalling 

 the distance between the eye and the tympanum ; snout acutely 

 pointed. Rostral not entering the nosti'il and separated from the 

 frontonasal by the nasals, which form a rather long median suture; 

 frontal as long as its distance fi'om the end of the snout; a 

 <;omplete series of granules between the two principal supraoculars 

 and the supraciliaries ; parietals once and half as long as broad, 

 in contact with the upper postocular, the outer border neai-ly 

 straight ; three small occipitals in a transverse line ; tempoial 

 scales small and granular ; tympanic and masseteric shields well 



* Boettger was therefore not justitied in saying (Bar. Senck. Ges. 1889, p. 205) of 

 Jy. dcpressa : " Sowohl De Filippi, als audi Camerano, v. Bedriaga und Boulenger
