Marta. A male from Calamar is intermediate between the species and 

 nigra. Two other Calamar specimens are referable to nigra.

This is the only Jacana we have taken in northern Colombia and the 

 Magdalena Valley, though as remarked above, one of two specimens from 

 Calamar is intermediate between nigra and melanopygia. Since J. spinosa 

 is the only species known from Brazil, it is obvious that with this form as 

 well, doubtless, as with melanopygia the "type-locality" is incorrect. I 

 list below all the specimens of nigra contained in our collections.
