Twelve specimens of this species were secured in the Cape Region of 

 Lower California by the Albatross Expedition. The localities represented 

 are: Cape San Lucas (A. M. N. H. Nos. 5437, 5473); San Jose del Cabo

Sceloporus lineatulus Dickerson

Range. — Santa Catalina Island, Gulf of California. 



Two specimens collected by the Albatross Expedition on Santa 

 Catalina Island were distinguished from S. zosteromus by Dickerson on 

 the basis chiefly of the strongly lineate lateral scales. In this character, 

 the single paratype (A. M. N. H. No. 5477) agrees excellently with the 

 type, each scale bearing two sharply defined brown lines, which combine 

 to form very irregular, curved lines extending from the black throat patch 

 nearly as far back as the groin. This specimen measures 96 mm. from 

 snout to vent, thus considerably exceeding the average for the penin- 

 sular zosteromus. The ventral color in both specimens is dark blue with- 

 out the broad light mid-ventral band common in S. zosteromus. I do not 

 find any distinctive characters in addition to size and coloration, and 

 Van Denburgh and Slevin (1921, p. 60) refer to lineate lateral scales as a 

 character of adult male zosteromus. I prefer, however, to maintain 

 lineatulus as distinct until further evidence bearing on the question is 

 available.
