36. Lampropeltis boylii (BAIRD & GIRARD). Three (4115, 

 4173-4174J from San Jose del Cabo, L. Cal. 



Prof, E. D. Oope, in Proo. Acad. Nat. Sci., Phila.. 1861, p. 301, 

 characterizes his L. boylii var. conjuncta by its having "the scales in 

 the white crossbands black bordered. Mr. Van Denburgh later * 

 raises this phase of this snake to specific rank. 



Now of the snakes of this species in th'^ Museum of the Zoologi- 

 cal Department here, as v/ell as a number of specimens from other 

 sources, all taken in the State of California, quite a number of adult 

 specimens are found to have black bordered scales in the white cro-s- 

 bands. Different degrees and phases are noticeable, so that I am in- 

 clined to doubt if those from ttie peninsula are of a distinct, tenable 

 form. 



37. Larapropeltis micropholes COPE. Two large specimens 

 of this snake are from Retalhuleu, Guatemala. They both have 

 seven superior labials and correspond to section B of Mr. Boulenger's
