196 FIELD MUSEUM OF NATURAL HISTORY ORNITHOLOGY, VOL. I. 



Family Plataleidse. 



Ajaia ajaia (Linn.). 



i specimen taken, a female. Apparently not previously recorded 

 from these islands. Mr. Ferry also took a specimen on Margarita. 



Family Ardeidre. 

 Egretta candidissima (Gniel.). 



Recorded by Mr. Hartert as having been seen on Aruba and Bon- 

 aire; not observed by Mr. Ferry. 



Hydranassa tricolor Mull. 



Given by Hartert as occurring on Aruba, who states, " Not plenti- 

 ful but of regular occurrence on Aruba and Bonaire. Identical with 

 South American specimens but different from the Mexican sub- 

 species, which is spread over the West Indies." (Ibis, 1893, p. 307.) 

 Its regular occurrence on Aruba is surprising, as all specimens which 

 I have examined from the islands (including Margarita and Trinidad) 

 are H. t. ruficollis. 



Hydranassa tricolor ruficollis (Gosse). 



Mr. Ferry procured four specimens on Aruba and others on Mar- 

 garita, all of which agree very well with specimens from the West 

 Indies and are readily distinguished from specimens of H. tricolor 

 from British Guiana and Brazil. 



Florida caerulea (Linn.). 



One adult specimen taken by Mr. Ferry. 



Butorides virescens robinsoni (Richmond). 



Two specimens taken, which I refer provisionally to this form, 

 as they approach nearer to it than to virescens. Hartert refers his 

 Aruba specimens to B. virescens (Ibis, 1893, p. 307) and suggests it 

 is probably the bird called B. striata by Peters (J. f. O.', 1892, p. 121). 



This group of Herons is decidedly in need of careful revision. 



Family Scolopacidre, 



Pisobia maculata (Vieill.). 

 3 specimens, i cT, 2 9.
