Ol'IIIDIA. 



9. S/enostoma humile B. & G. 



10. Procinura cemula Cope, gen. et. sp. nov. 



Char. gen. Dentition opisthoglyph. Form that of Elapomorphus. 

 Two nasal, one loreal, and one preocular plates ; internasals and prefron- 

 tals distinct. Scales smooth, excepting those of the posterior dorsal and 

 caudal regions, where they are keeled, those of the latter so much so as to 

 be tubercular. Anal plate double. 



This genus is near to Scolecophis Cope, but the peculiar tubercular can- 

 nation of the tail distinguishes it. The only known species inhabits a 

 rocky, mountainous region, and I have little doubt that this peculiar char- 

 acter enables the animal to force itself into the earth or beneath stones. 

 The tail is used as a fulcrum in pushing against rough and resistant bodies. 



Char, specif. Scales broad rounded, in fifteen longitudinal series, the 

 median rows rather smaller than the lateral, of which three rows are equal. 

 Muzzle projecting beyond the mandible, rounded, the rostral plate visible 

 from above, presenting an obtuse angle posteriorly. Top of head flat. Pre- 

 frontals much wider than long, their external canthal border equal to that 

 of the internasals. Frontal wide, sending a long angle backwards. Parie- 

 tals short, wide ; temporals 1-2, the first small, as deep as long. Superior 

 labials seven, all except the first, deeper than long, the third and fourth 

 entering the orbit. Preorbital vertical, narrow, not reaching frontal ; pos- 

 torbitals two, equal and small. Loreal quadrangular. Inferior labials 

 eight, fourth largest ; pregeneials three times as long as postgenei&ls and 

 separated from gastrosteges by six rows of scales. The dorsal carina? first 

 appear on the twenty-second transverse row of scales anterior to the vent 

 and occupy the median nine series. All the caudal series are keeled, and 

 as they are wider than long, the free apices of the keels projecting, give 

 them a depressed pyramidal form, Gastrosteges 148 ; urosteges 41. 



In the coloration of the body this species is an almost exact repetition of 

 the Elaps fulvius. It is surrounded by wide black rings, which arc broadly 

 bordered with yellow, and separated by red interspaces of twice their 

 width. The scales of the red spaces have each a central black spot which 

 are more distinct than in E. fulvius, on the anterior part of the body above 

 the sides ; posteriorly they are weaker. The black annuli pass round the 

 belly, but all are somewhat broken anteriorly. Between them the gastros- 

 teges have black shades. The coloration of the head differs from that of 

 the E. fulvius in having merely a large black spot covering the parietal, 

 superciliary and frontal plates, and extending round the eye but not reach- 

 ing the edge of the lip. Muzzle and chin unspotted. 



Total length, M. -.364 ; length of rictus oris, .011 ; length of tail, .0(51. 



Although this curious and handsome serpent so much resembles the 

 Elaps fulvius, it is not yet known that the two species inhabit the same 

 region.
