fDon Die<ro, ex Allen) 



Additional records: Cienaga (Univ. Mich. Exp.). 



Three specimens : Don Diego and Gaira. 



As these are all in immature plumage they are not determinable as 

 to subspecies, but are probably referable to ruficollis, since the typical 

 form, so far as we know, is restricted to the Guianas and Brazil. 



A pair of Louisiana Herons were taken in a swampy pasture near 

 Gaira, September 11, 1913. Mr. Smith's collectors secured two speci- 

 mens at Don Diego, May 5 and 9, 1901, and the University of Michi- 

 gan Expedition secured two more at Cienaga in August, 1913. Evi- 

 dently it is rare in this section. 



8. Florida caerulea (Linnaeus). 



Ardea cmrulea Wyatt, Ibis, 1871, 384 (Cienaga). 



Florida ccerulea Todd, Ann. Carnegie Mus., X, 191 6, 179 ( [Santa Marta re- 

 gion], Colombia; crit.). 



Additional records: Gaira (Carriker). 



Fourteen specimens: Bonda, Cinto, Trojas de Cataca, and Punto 

 Caiman. 



In the paper last cited the writer has. given reasons for declining to 

 recognize a southern subspecies carulescens. Since this was written 

 Cayenne examples have come to hand; they prove to be inseparable 

 from either Colombian, West Indian, or Florida birds, and confirm the 

 conclusions already reached. 



The Little Blue Heron is the most abundant of its family in this 

 whole region, and is found throughout the littoral Tropical 'Zone 

 wherever there is a little water, from Santa Marta to Fundacion, and 

 also to the eastward as far at least as Dibulla. 



9. Pilherodius pileatus (Boddaert). 

 Two specimens : Cinto and Tucurinca. 



Mr. Smith's collection contained one fine adult of this species, 

 which he said was taken at Cinto (the label having inadvertently been 

 left blank). This appears to be the first specimen of this beautiful 

 heron ever collected in Colombia. A second specimen was shot by the
