sent specimen which only measures 49 mm between snoiit 

 and vent the hind limbs are 25 mm in length and reaches 

 somewhat beyond the axilla. 



By the smooth scales my species corresponds with T. 

 Icevicauda Cope which, however, has the tall entirely smooth. 

 The colour pattern of this latter species appears also to %e 

 different from that of the present species, and I venture to 

 presume that the differences regarding the plates of the head 

 and the scales of the body which, as stated above, exist 

 between T. hijasciaius and T. romani are to be found between 

 this latter and T. Icevicauda as well. This opinion is founded 

 on the fact that Cope does not mention anything about the 

 plates and the scales, when he enumerates the few differences 

 which he is able to state between his species, T. Icevicauda^ 

 and the older T. hijasciaius. It seems thus to be very prob- 

 able that no such differences exist between them, and that 

 all the characteristics which I have recorded being of distin- 

 guishing value in this case between T. romani and T .bifasciatus 

 may also distinguish the former from T. Icevicauda. 



Mabiiia nig:ropalmata n. sp. 



Snout depressed, obtuse. Lower eyelid with an undivided 

 transparent disk. A postnasal; anterior loreal narrowly in 

 contact with the first labial ; siipranasals completely separated 

 by the frontonasal, the hind margin of which is angulate; 

 prsefrontals forming a suture mesially. Frontal small, angu- 

 late in front, much narrowed behind, in contact with the 

 second supraocular and usually also with a narrow wedge of 

 the first of these shields. Four supraoculars, second largest, 

 five supraciliaries; frontoparietals united into a single shield; 

 interparietal somewhat larger than the frontal; parietals in 

 contact behind the interparietal. Three (two) pairs of nuchals, 

 four or five supralabials anterior to the subocular. Ear- 

 opening small, rounded, without projecting lobules. Scales 

 smooth, 26 — 30 round the middle of the body, a little larger 

 on the back than on the sides. Limbs overlapping, when 

 adpressed against the body. Subdigital lamellae smooth; tail 

 1 Va the length of head and body.
