median patch if they belong with iS. occldenlidh, and never have two 

 lateral patches if referable to S. Iiixen'nlux. Females of the latter 

 species have either one or two blue patches, while those of the 

 more northern form usually have two or none." 



Nov/ the specimens recently received and tabulated above all 

 have distinctly a ainijli' large spot on the tTirout; which sometimes cov- 

 ers a greater part of the legion under the htad. Besides these there 

 are a number "in which the two blue patches have extended to and 

 even njerged on the median line," and also others which show differ- 

 ent variations of the blue on the throat. In some 1 regret to say the 

 color has faded and would lend no evidence on either si<!e. The 

 black ventral coloration often present in the southern specimens is 

 also seen in the northern ones. In regard to the northern females: 

 a number of them in the collec!ion have one spot upon the throat, as 

 the males, and ottiers have either two or none, while I found none 

 of the southern females that had two distinct patches. The S. biseri- 

 aius form on the other hand have but one spot on the throat, in both 

 males and females, and at the best have but an extremely slight line, 

 not worthy of consideration, on the center of the throat. Tiie collec- 

 tion of the Department of Zoology also contains others, which per- 

 haps may have been anions!; the "many hundreds" Mr. Van Denburgh 

 exar.ined, that have distinctly but one throat patch. They are tab- 

 ulated below :
