covering three aad two half scales to opposite the vent. It then contracts 

 and continues to the end of the tall. A. narrow hlack band extends from 

 the gular region to the end of the tail across the ends of the gastrosteges, 

 and is separated from the brown lateral band by a yellow stripe. Inferior 

 surfaces unspotted, but shaded delicately with dusky. The centres of the 

 scales of the first and second rows on the neck have a black central line, 

 as have several scales on the throat and gular region. Some small black 

 spots on the fourth, fifth and sixth superior labial scuta. 



Total length, M., .668; length of tail, .153; of mouth to canthus, .016. 



This very pretty species resembles the Atomophis trilineatus Burm., 

 and the Pkilodryas iceniaius Peters. Besides the peculiarity in the double 

 loreal plates, it differs from the former in the rounded muzzle. It la 

 obliquely truncate in the species of Burn\eister. According to Jan's figure 

 the latter has the seventh superior labial a little longer than high, while 

 in the D. lativittatus it is higher than long. The inferior lateral yellow 

 stripe in the A. trilineatus is not black-bordered below. In the Pkilodryas 

 tmniatiis the preocular plate is scarcely visible from above ; there are only 

 seven superior labials, and the scales are said to be without pits.

 Several individuals, all alike and differing in color from the true C. du- 

 rissus Linn. (C. horridus D, & B.). This is a brown snake with brown 

 dorsal rhombs with narrow yellowish borders. The C. durissus is a yellow 

 snake with brown dorsal rhombs which have yellow centres, the brown 

 being little more than a border. The C. terrifica is figured by Seba, and 

 by Wagler as above. 



CONCLUSIONS. 



The collection made by Mr. Smith is productive of a good many inter- 

 esting results, especially to the knowledge of geographical distribution. 

 Such are the great extension of the range of the anurous genus Prosthe- 

 rapis among Batrachia ; of Anolis and Scartiscus among lizards ; and of 

 Rhynchonyx and Dirrhox among snakes. The rediscovery of a few spe- 

 cies brought from the same region a half century ago by the Austrian, 

 Johann Natterer, is of considerable interest. Such are the species Palu- 

 dicola nattereri and Philodryas nattereri Steind. Other rare species only
