3" Bocourf s (Mission scientifique au Mexique et dans TAmgrique centrale, Rept. livr. 12, 

 1S90, p. 722) name was proposed inadvertently in his synonymy of Drymobius {Eudryas) 

 laevis Fisclier by recording Jan's designation (never published) on some of the Paris 

 Museum's specimens. Although Jan obviously used the name for Mexican specimens, for- 

 tunately his intentions need not be considered ; if they were the name miglit well replace 

 one of those more recently proposed. Bocourt's use of the name, not Jan's intention, deter- 

 mines the allocation of it. Since Bocourt described both Guatemalan and Mexican speci- 

 mens (the latter either slevini or vcraec-rucis, or both), to avoid confusion the name 

 H. mexicanus Bocourt is restricted to the Guatemalan specimens (laevis). 



Another name proposed by Bocourt (op. cit., pp. 721-722, pi. 51, fig. 1) and not previously 

 allocated, is Drymobius (Eudryas) boddaerti var. californiensis. Although pattern and 

 number of ventrals are rather like those of some subspecies of melanolomus, the name 

 appears to be based upon a specimen of D. b. boddaerti.
