naga Grande, not far from the town of Cienaga, October i8, 1913. 

 A few others were seen, but evidently it is not a common species, and 

 is of course a winter resident only. 



89. Thalasseus sp. 



Thalasseus eurygnathus Ridgway, Bull. U. S. Nat. Mus., No. 50, VIII, 1919, 

 474 (Buritaca). 



One specimen: Buritaca. 



A single specimen of a tern in juvenal dress, collected September 

 19, 1899, appears to belong to some species of this generic group, but 

 in the absence* of suitable material for comparison it cannot be cer- 

 tainly identified at present. Mr. Ridgway, who handled the specimen 

 some years ago, indeed referred it to Sterna eurygnatha Saunders, but 

 it seems much too small for this species, having a wing only 250 mm. 

 long, and a bill not at all corresponding to the description. These 

 peculiarities may of course be due to the youth of the individual in 

 question, which was probably reared not far away from the locality 

 where it was taken. 



Family RECURVIROSTRID^. Avocets. 



90. Himantopus mexicanus (MuUer). 

 Himantopus nigricollis Wyatt, Ibis, 1871, 383 (Cienaga). 



Five. specimens: Punto Caiman and Gaira. 



A few were seen around the salt ponds at Gaira on May 21, 1913, 

 while it was fairly common along the sea-beach at Punto Caiman in 

 late September and early October of the same year. Wyatt says that 

 he met with this species in the shallows of a lagoon near Cienaga in 

 December, 1869, and several specimens were taken at the same locality 

 in August, 1913, by the University of Michigan party. Both of the 

 Gaira specimens are birds of the year, one of them so young as to 

 render it very probable that it was hatched in the immediate vicinity. 

 All but one of the Punto Caiman specimens are also immature. 



Family SCOLOPACID^. Snipes, Sandpipers. 



91. Bartramia longicauda (Bechstein).
