ludoviciana for the southern form since the type locality was Lou- 

 isiana. 



So far as I can judge from the material in hand, I think it 

 hardly worth while to attempt such a division. 



The exact relationships of some of the races of Stumella is very 

 easily traced, while in the case of others it is less apparent. 



The true Stumella magna is found throughout the eastern United 

 States from Maine southward, and westward to the edge of the 

 Plains. In the southern portion of its range it tends to smaller size 

 and darker coloration, as already described. 



To the southwest, magna extends into northeastern Texas ; one 

 from Jefferson Co. (No. 41,444, Coll. Wm. Brewster) being very simi- 

 lar to the eastern bird. In the Rio Grande Valley, however, the larks 

 pass into a very light race, fully as light as the prairie neglecta, with 

 the wings even grayer. This is the form here named hoopesi. 



The exact range of this bird I am unable to trace ; all the speci- 

 mens I have examined were from Brownsville and Laredo. 



In southern Mexico and Central America we find the race mexi- 

 cana, a very dark bird, most nearly resembling the larks from Flor- 

 ida. This, in turn, passes into the South American meridionalis, 

 which is of about the same coloration, but differs in its proportions, 

 especially in the very large bill. The peculiar form called inexpectata 

 is known only from three specimens from Segovia River, Honduras. 

 They are remarkable for their extremely small size, but resemble 

 mexicana in coloration. 



On the north mexicana probably grades into hoopesi, but I have 

 no specimens from northern Mexico showing this gradation. One 

 individual from Huachuca, Arizona (March 1, 1887, male, No. 

 23,198, Coll. Wm. Brewster), however, may, perhaps, be so regarded. 

 It has the narrow breast band of mexicana, and is browner above 

 than hoopesi from the Rio Grande Valley, which, in other respects, 

 it much resembles, agreeing strictly with this form in the distribu- 

 tion of yellow on the throat. 11 



Having thus traced the races most clearly connected with magna 

 and their offshoots, it remains to speak of the relationships of neg- 

 lecta. This form is found from the eastern border of the plains 



"Another bird labelled as shot at the same time and place (No. 23,199, 

 Coll." Wm. Brewster) is a typical male neglecta. It has the plumage much 

 worn, as in a breeding bird, while in the one referred to above, the plumage 

 is but little worn, agreeing well with November birds from Arizona. It is 

 strange that two such specimens should be taken on the same date !
