its length not. quite twice the diameter of the eye. Rostral 

 moderate, not advancing on the internasals ; latter longer than 

 broad ; frontal as long as its distance from the tip of the 

 snout, its front edge nearly straight ; parietals longer than 

 frontal, narrowed and including a considerable notch behind. 

 Eight supero-labials, fourth and iifth entering the eye ; one 

 preocular, two postoculars, lower smaller than upper ; a single 

 anterior temporal ; eight inferior labials, five in contact witii 

 mentals; latter, hinder pair longest. Scales in seventeen rows. 

 Gastrosteges 154 or 156 ; anal bifid ; urosteges 55 or Q^. 

 l^rown above, upper half of supero-labials yellowish, lower 

 half blackish ; a black streak from the eye along the side of 

 the neck ; a light black-edged spot on each side of the nape ; 

 a rather indistinct, interrupted, yellowish line along each side 

 of the front half of the body, between the fifth and sixth rows 

 of scales ; a black stripe along the middle of the tail and of 

 the hind part of the back ; yellow or brownish-yellow beneath ; 

 outer edge of gastrosteges and urosteges, and sometimes front 

 edge of former, black. 



Length of the two specimens : — Head and body 514, 

 410 millim.; tail 127, 135 millim. 



iMilligalli. Two specimens. 



This species bears a close resemblance to Coi'onella decorata^ 

 Gthr. (Cat. Colubr. Sn. p. 35), from Mexico, but differs in 

 the narrower internasals, shorter tail, size, and coloration. 



[Having compared the type specimens of C. decorata^ Gthr. 

 (1858), with the figure of Enicognathus vittatus, Rapp, MS. 

 (Jan, Arch, per la Zool. ii. fasc. ii. p. 61, 1863 ; and Iconogr. 

 gen. Ophid. livr. 16, pi. ii.), I am convinced that the two 

 species are identical.] 



16. Liophis regince (L.), var. alhiventris, Jan. 



Two adult and two young from Milligalli, and one half- 

 grown from Tanti. 



The var. quadrilineatus^ Jan, is represented by two speci- 

 mens, which are evidently the adult state of var. albiventris. 



17. Liophis alticolus. 

 Opheonwrphus alticolus, Cope, Proc. Ac. N. S. Philad. 1868, p. 102. 



Olalla, near Tumbaco (8490 feet). One fine specimen, 

 which was brought in to Mr. Whymper alive, and excited 

 much curiosity amongst the natives. 



18. Liojyhis splendens, Jan.
