Measurements.— Five males: wing, 79-83.5 (81.5) ; tail, 79-83 (81.2) ; bill from 

 base, 15.5-16 (15.7); tarsus, 21.5-22.5 (22). Five females: wing, 76.5-80 

 (78.7); taU, 77.5-81 (79.3); bill from base, 15-16 (15.4); tarsus, 21-23 (21.7). 



Range. — Island of Barbados. 



Specimens examined. — 5 cf , 7 9,2 juvenals. 



Remarks. — This entire series is composed of badly worn and 

 abraded summer specimens and cannot be relied upon to show 

 the existence of any color characters. However, no authors have 

 remarked any color differences in this race that do not come with- 

 in the range of individual variation indicated under E. m. marti- 

 nica. 



Elaenia martinica riisii (Sclater) . 



Elainea riisii Sclater, P. Z. S., 1860, p. 314 (St. Thomas, W. I.). 



Subspecific characters. — Smaller than E. m. martinica; much grayer and paler 

 above (buffy olive or citrine drab) ; wing bars wider and whiter (less olive) ; a 

 well-defined grayish white tip to the tail; below much as in the typical form 

 and equally variable, but very much paler and grayer, particularly when seen 

 in series. 



Measure7nents. — Males: wing, 73.5-80; tail, 66-77; bill from base, 14-16.5; 

 tarsus, 19.5-23. Females: wing, 69-75; tail, 61-73; bill from base, 14-15; 

 tarsus, 18-21. 



Range. — Riise's Elaenia has a peculiar, rather anomalous 

 distribution. It occurs on Vieques, Culebra, and Culebrita 

 Islands just east of Porto Rico, though not recorded from that 

 island; neither does it seem to be definitely recorded from St. 

 Croix! It is common on the remaining Virgin Islands; examples 

 from Anguilla and Antigua would appear to be referable to this 

 form. I have not examined representatives from St. Barts, St. 

 Martins, or Barbuda. It occurs on some of the islands off the 

 north coast of Venezuela — Aruba, Curagao, and Bonaire; at least 

 specimens from these islands are indistinguishable from birds from 

 the northeastern Antilles. At the same time I feel confident that 

 here is not a case of discontinuous distribution, but a simple one of 

 parallelism or convergence. 



Elaenia martinica caymanensis Berlepsch. 



Elaenia martinica caymanensis Berlepsch, Proc. Fourth Int. Orn. Congress, 

 1907, p. 394 (Grand Cayman). 



Elaenia martinica complexa Berlepsch, Proc. Fourth Int. Orn. Congress, 

 1907, p. 395 (Cayman Brae). 



Suhspecific characters. — Similar to E. m. riisii, but much larger; more uni- 

 formly yellow below; wing bars and edging of the inner secondaries much wider. 



Measurements. — Males: wing, 82-88; tail, 72-83; bill from base, 14.5-16.25; 

 tarsus, 18-23. Females: wing, 77-81; tail, 69-76; bill from base, 13-16; tarsus, 

 19.5-21. 



Range.' — The Cayman Islands (Grand Cayman, Cayman Brae, 

 and Little Cayman). 



Remarks. — The specimens on which von Berlepsch based his 

 E. m. complexa were badly discolored by reason of the preserva- 

 tive used by the collector in their preparation. Our series from 

 the Caymans, collected by W. W. Brown in 1911, fails to show any 

 differences between the birds from the three islands.
