Description. — M. C. Z. No. 1327, an adult male from Port-au-Prince, 

 Haiti, collected on May 20, 1863, by O. Ackerman. Rostral much 

 broader than high, rectangular, with a very small nick in the posterior 

 margin for the anterior part of the very minute internasal and a 

 median cleft extending forward for more than one-half the height 

 of the shield, in contact with two large supranasals on each side of 

 the small internasal; first supralabial narrowly entering the nostril, 

 and in contact behind with the lower postnasal; nostril between the 

 rostral, first supralabial and three scales behind and above, the upper 

 one (supranasal) being much the larger; 11 or 12 upper labials, the 

 last becoming very small and merging into the other granules, the 

 suture between the tenth and eleventh falling below the center of the 

 eye; 9 lower labials on the right side, 10 on the left, the last ones grad- 

 ually becoming smaller; top of head covered with granules, which 

 are largest on the snout, especially on the canthus rostralis, with a 

 few coarser tubercles behind the eyes; eye a little nearer to the ear 

 than to the end of the snout, its diameter only a little over half the 

 length of the snout; ear opening vertical, oval, its maximum diameter 

 somewhat greater than the height of any supralabial; temples granular 

 like the top of the head, with scattered, keeled tubercles; mental tri- 

 angular, slightly wider than rostral, its free border almost twice as 

 wide as nearest infralabial, its posterior angle very acute; two large 

 chin shields on each side, the median pair slightly the larger and in 

 contact behind the rostral, the outer pair separated by three or four 

 granular scales, wliich in turn soon give way to very small granules 

 covering the rest of the chin and the anterior part of the throat; 

 upper surface of body and flanks covered with granules a little larger 

 than those of the back of the head, interspersed with large, convex, 

 heavily keeled tubercles, each about as long as three granules; these 

 tubercles show a tendency to form irregular longitudinal rows, there 

 being about 12 across the middle of the back; under parts of body and
