4G0 Dr. E. Lonnberg on Snahes from 



quite or almost unspotted ; but the young ones have nume- 

 rous more or less confluent spots on the back and alonj^ the 

 sides &c., as the author quoted states. On some specimens 

 there are quite fine minium-red stripes between the scales, 

 which stripes on the tail become broader and encroach more 

 on the scales, so that the tail appears almost brick-red towards 

 the end. 



Bhadincea occipitalis, Jan. 

 A small specimen from Tatarenda. 



Oxyrhopus rhomhifer^ Dam. & Bibr. 



A beautiful specimen from Quinta, Province de Jujuy, 

 Argentine. It is not recorded in Berg's '' Fauna Erpetologica 

 Argentina" (An. Mus. Nac. de Buenos Aires, t. vi. 189Sj. 



This snake, as well as Lystrophis semicinctus, may be said 

 to strikingly mimic Elcqjs in their coloration. 



Oxyrhopus cJcelia (Daudin). 

 A large black specimen (IGO centim.) from Tatarenda, 

 Bolivian Chaco. 



TacTiymenis peruviana, Wiegm. 



Two specimens of this snake were collected near Moreno, 

 Puna de Jujuy, Argentine, 3500 m. above the sea-level. 



Philodryas Erlandi'^^ sp. n. 



Eye a little longer than half its distance from the end of 

 the snout (in the young its length equals its distance from 

 the nostril). Snout a little prominent and obliquely truncate. 

 Eostral much broader than high, just a little visible fromabove. 

 Internasals shorter than praifrontals. Frontal not quite once 

 and a half as long as broad, a little longer than its distance 

 from the snout, not quite as long as the parietals (almost as 

 long in the young). Loreal longer than deep. One prae- 

 ocular, not reaching the frontal. Two postoculars. Tem- 

 porals 1+2. Eight upper labials, fourth and fifth entering 

 the eye. Five (four in the young) lower labials in contact 

 with the anterior chin-shields, which are of equal size with 

 the posterior ones. Scales smooth (with single apical pits), 

 in 19 rows. Ventrals only very obtusely angulate, 230-236 ; 

 anal divided ; subcaudals 140-150. Bluish green anteriorly 



* I take the liberty of dedicating tliis species to my friend Baron Erland 

 Nordensliiold.
