Todd-Carriker: Birds of Santa Marta Region, Colombia. 49 



fifty-six forms sixteen were positively identified in the field, but no 

 specimens were secured. On the other hand no less than seventy- 

 seven species and subspecies have been added to the Santa Marta list as 

 a result of the work of the junior author, while thirty-six species and 

 subspecies have been described as new to science on the basis of mate- 

 rial collected by him in this region. 



Species Described from the Santa Marta Region. 

 It will be of interest at this point to give a list of the various species 

 and subspecies which have been described from the Santa Marta region 

 from 1847 down to the present time, one hundred and sixty-one in num- 

 ber. Not all of these are valid names, of course, and not all of them 

 represent forms which are confined to this region; in fact, it is known 

 that in several instances the assigned locality must have been a mis- 

 take. But even after all allowances have been made, few continental 

 regions so restricted in area can boast so many peculiar forms. Of 

 such no less than seventy-two are now known, and very probably more 

 remain to be discovered. In addition there are fifty-four forms, now 

 considered valid, which were originally described from the region, 

 but have been found to range beyond its confines as here understood.
