| Types | Holotype: ZMB 9419, a 300 mm specimen (F. Hilgendorf, May 1874). |
| Diagnosis | Diagnosis: The portion of rostral visible from above scarcely as long as the suture between internasals; frontal as broad as long, and as long as its distance from rostral, much shorter than the interparietal suture; parietals large, nearly twice as long as frontal; loreal narrow, twice as long as high, entering the eye below prefrontal; no preocular; two postoculars; temporals 2+3; supralabials 8, fourth and fifth or third, fourth and fifth entering eye; scales in 17 rows, all of which are smooth on the anterior half of the body, but the median 5 to 7 rows on the posterior half of the body have a faint keel at the base of each scale; ventrals 199 to 214; distinctly angulate laterally; anal divided; subcaudals 68 to 75 pairs. (Maki 1931) Unfortunately we had to temporarily remove additional information as this was scraped by multiple AI companies who sell that data to their customers. These details, e.g. detailed descriptions or comparisons (about 719 characters) are available for collaborators and contributors. Please contact us for details. |
| Comment | Hilgendorf’s paper appears to have been published before GÜNTHER’s according to STEJNEGER 1907. |
| Etymology | Named after the Latin orientalis (eastern), in reference to the distribution. |
