* As remarked by Bocourt, the orbital ring of scales in this species is sometimes separated from the 

 superior labial plates by a row or two of scales, as in the B. constrictor. In four specimens from 

 Colima it is so separated in three, and iu two from Vera Cruz it is so separated on both sides in one, 

 and iu the other, on one side of the head and not on the other. In a specimen from Groytown, Nica- 

 ragua, referred in the Proceedings of the American Philosophical Society, 1877, p. 19, to the B. ortunii 

 it is sep.irated by two rows, .and there are iifleen scales between the eyes instead of the usual number, 

 eleven. 1 believe all these individuals lo beUmg to one species, which is, as stated by Suuiichrast, 

 generally distributed in Mexico. The numbers of scuta and scales in several specimens is as follows : 

 Greytown, scales, 09 rows ; gasteosteges, 24".' ; ? Tehuantepec, sc. 69 ; g. 249, mosteges, 58 ; Colima 

 (four specimens), sc. 71-3-4; gasteosteges (one specimen), 242; mosteges, 58; Cordova, Vera Cruz, sc. 

 73; Mirador, Vera Cruz, sc. 05; g. 238; u. 53. There are then thi-LO well-Cefined specie.-? of Boa: the 

 B. constrictor, B. imperator, and B. divinilo'juax. The B. ortonii must be referred to the Jt. imperator^ 

 and the B. mcxicana has not yet been sati: factorily separated from the B. diviniloquax. The JB. 

 aques continues to be represented by the type specimen otdy.
