that it is a seasonal feature, characteristic of the fr(>sh i)liimage, 

 and fading; with the adxance of the breeding season. Althoujjh con- 

 spicumis ii\ hotli the New Pro\idence and dreat Inagiia hirris, it is 

 bareh' indicated in the specimens from Andros and Abaco, and 1 hnd 

 precisely i)arallel changes in a scries of the allied form from Cuba. 



45. Blacicus bahamensis (Br>ant). 



Twelve specimens: New Providence (Blue Hills); Andros (Staniard 

 Creek); Abaco (Sand Bank). 



The examples from Andros and Abaco, being more or less worn and 

 faded, have almost entirely lost the yellowish suffusion of the under 

 parts, so obvious in the fresh-])lumaged specimens from New Provi- 

 dence, while the grayish white edgings of the secondaries have also 

 become obsolete. These changes are the same as take place in the 

 last species, as above noted. 



While I follow Mr. Ridgway in recognizing Blacicus, it is difficult 

 to see any good reason for its separation from Myiochanes, judging 

 from the present species alone. 



46. Mimus polyglottos polyglottos (Linnaeus). 

 One specimen: Abaco (Spencer's Point). 



In common with Messrs. Cory, Allen, and Ridgway, I find that the 

 Mockingbird of the northern Bahamas, represented by the above 

 specimen, is clearh- refcral)le to the continental form. The specimen 

 in question is somewhat worn, but agrees well in color and size with a 

 Florida example in similar condition, especially as regards the tail- 

 pattern. It measures: wing 115 mm.; tail 122; culmen 18. 



47. Mimus polyglottos orpheus Linnaeus. 



Twelve specimens: Great Inagua (Alfred Sound, Mathcwtown). 



Compared with M. p. polyglottos, the Great Inagua bird, by reason 

 of its decidedly smaller size, whiter under parts, and more extensively 

 white tail, would seem to be sufficiently distinct to stand as a full 

 species, but its distinctness from the other Antillean forms is open to 

 question. After examining the fine series of West Indian Mocking- 

 birds in the Field Museum, as well as considerable additional material 

 in other collections, I am very doubtful as to the propriety of recog- 

 nizing more than one form. The characters relied on by Mr. Ridgway 

 to separate orpheus, dominicus, and elegans from each other prove upon 

 comparison to be all very subtle and more or less inconstant — the 

 relative proportions, relative amount of white on the wings and tail,
