with some general remarks on the vexed question of the 

 variation of the phimage in the sexes and ages of these little 

 Parrots. His " key to the species/^ which follows, contains 

 short characters by which both sexes of the eleven species 

 and subspecies may be recognized. Of these four are now 

 described as new, namely : — Psittacula passerina vivida, from 

 Bahia ; P. insularis, from the Tres Marias Islands ; P. ex- 

 quisita, from Colombia ; and P. deliciosa, from Diamantina, 

 Lower Amazons. Dr. Hartlaub has pointed out (Ibis, 1888, 

 p. 493) that Mr. Ridgway appears to have overlooked* his 

 lately-published article on Psittacula (P. Z. S. 1885, p. 614), 

 and that P. exquisita, Ridgway = P. spengeli, Hartl., and 

 P. deliciosa, Ridgw. = P. cyanochlora, HeiYtl.^ P. insularis 

 ("similar to P. cyanopygia, but larger and darker '') can 

 hardly be considered more than a subspecies. 



35. Ridgway on Birds from the Caribbean Islands and 

 Honduras. 



[Catalogue of a Collection of Birds made by Mr. Cbas. 11. Towusend 

 on Islands in the Caribbean Sea and in Honduras. By Eobert Ridgway. 

 Proc. U.S. Nat. Mus. 1887, p. 572.] 



The collection was made in the islands of Grand Cayman, 

 Swan Island, and Ruataii, and in two localities in Honduras. 

 In Grand Cayman, 175 miles south of Cuba, which had been 

 already visited by Mr. Cory's collector in 188G, examples of 

 thirteen species were obtained. Of these Dendroeca auri- 

 capilla (a form of D. petechia) is described as a new species, 

 and Columbigallina passerina insularis as a new subspecies. 

 In Swan Island, which lies 200 miles south-west of Grand 

 Cayman, examples of thirty species were found. Of these 

 Contopus viciims (allied to C. virens) and Butorides saturatus 

 (like B. virescens, but darker !) are described as new. In 

 Ruatan only three species were met with. At Truxillo, in 

 Honduras, examples of 56 species were procured. Of these 

 Mr. Ridgway separates a Thamnophilus (of the doliatus 

 section) as T. intermedins, a Centurus as C. santacruzi pauper, 

 subsp. nov., and a Pigeon of the genus Engyptila, allied to
