beetles to 3.34 per cent. One bird had eaten nothing but four back swimmers 

 (Xotonecta sp.), and these made 16.66 per cent. Fly pupa figure largely in two 

 stomachs, forming 21.66 per cent of the total, and snails (Planorbis sp.) 13 per 

 cent, while miscellaneous animal matter amounts to 12.50 per cent. The small 

 quantity of vegetable matter present was rubbish. The numbers of Diptera 

 eaten speak well for this sandpiper. 



LEAST SAXTJPIPER. PisoMa minutUla (Vieillot). 



PUTILLA., PUTILLA MeXUDA, SAEAPICO PeQUEXO. 



Gundlach (1878, p. 376) records the least sandpiper as a winter visitant. It 

 is still common during migration. Stahl (1887, p. 449) says that the birds 

 arrived from the north at the end of August in 1886, and that a few indi- 

 viduals remained through the summer. Bowdish (1902-3, p. 360) notes the 

 first arrivals for Porto Rico September 23. 1900, and September 4, 1901. He 

 also found them common on Mona Island August 9 to 21, 1901. I saw one at 

 the Laguna de Guanica May 26, and August 2S one at Joyuda, near Cabo Rojo. 

 Further observations may show that they are more common in other localities. 



Food. — The stomach of the single bird taken contained the heads of more than 

 100 minute fly larvae (75 per cent) and fragments of small beetles (Heteroce- 

 rus sp.) (25 per cent). 



WHITE-RrMPED SA:\~DPIPER. Pisolia fuscicoUis (Vieillot). 



PUTILLA. 



The white-rumped sandpiper is a rare migrant and possibly a winter visitant 

 to Porto Eico. Bowdish (1902-3, p. 360) took one near Mayagiiez October 2, 

 1900, the first record for the island. April 15 I saw two on the north shore of 

 Culebrita Island. The species should occur on mud fiats bordering lagoons and 

 in similar localities. 



PECTORAL, SANDPIPER. Pisohia maculata (Vieillot). 



PUTILLA, PUTILLA PlXTA., SAEAPICO MAXCHADO. 



Gundlach (1878. p. 375) records the pectoral sandpiper as a winter visitant 

 from September to April, but it probably occurs more co mm only during migra- 

 tion. Stahl (1887, p. 452) says that it lingers late in spring and that a few 

 individuals are found through the summer. Bowdish (1902-3, p. 359) secured 

 specimens September 26. 1900, and October 2 near Aguadilla. I saw a flock of 

 about a dozen around a little tidal pool near Guayanilla August 24. 



STTLT SANDPIPER. Micropalama himantopus (Bonaparte). 



PUTELLA., SAEAPICO ZAXCUDO. 



On August 28 a pair of stilt sandpipers came driving swiftly down the coast 

 at Joyuda, near Cabo Rojo, and one was taken. They are winter visitants, 

 apparently rather rare, and are to be looked for on mud flats bordering lagoons 

 and about shallow pools of water with muddy shores. Gundlach (1878, p. 373) 

 says that they arrive in September. Sundevall (1869, p. 602) received three 

 specimens from Hjalmarson. Stahl (1883, p. 151) had one specimen in his 

 collection. The stomach of one bird, taken about 11 in the morning, contained 

 gravel alone, which would indicate that this individual was a migrant and had 

 come a long distance. 



WLLSON'S SNIPE. Gallinago delicata (Ord). 

 Becacixa. 



According to Gundlach (1878, p. 368) Wilson's snipe is a winter visitant, 

 occurring from September until spring. December 19, 1911, a dozen were seen 

 about a pool in a low field near Rio Piedras and one was taken; another was
