131 of this volume. Th.ey were collected at San Telmo, 

 June 17; near Ensenada, June 12; and between San 

 Vincente and Salado, June 15, 1893. 



LiCHANURA ROSEOFUSCA Cope. 



A young specimen of this snake (L. S. Jr. U. No. 

 1125, vicinity of Ensenada, L. C, June 8, 1893) is in- 

 teresting because it shows the instability of the chief char- 

 acter upon which L. 07'cutti is based. On one side of the 

 head there are two true loreals, as in L. orciitti, while on 

 the other there are three, as in L. roseofiisca. The scale 

 rows are forty-one in number. 



Lampropeltis boylii (B. & G.) 



The single specimen (L. S. Jr. U. No. 1724) is typical 

 of this species. It was secured in the foothills of San 

 Pedro Martir Mt., July 11, 1893. 



Salvadora grahami.^ B. & G. 



One typical specimen (L. S. Jr. U. No. 1723) was 

 collected on San Pedro Martir Mt., July 6, 1893. With 

 it is the following note: " Sage brush — partly buried in 

 sand." 



Bascanion piceum Cope. 



That B . -piceitm is based on anything more than mela- 

 nistic individuals of B . flag ell mn frenatum, I have great 

 doubt. The evidence at hand, however, is not quite suffi- 

 cient to prove their identity, and it seems better to re- 

 cognize them as distinct forms than to run the risk of 

 premature ' lumping.' The difference seems to be purely 

 one of coloration, for although the type of B . ficeum 

 (from Camp Grant, Arizona) has nineteen rows of scales, 

 all the (5) specimens that have been found since have 

 seventeen.
