jugulum, the shafts being white; on its sides alone are there indications of 
these, which on the sides of the breast and belly become more distinct than 
in M. bahamensis, owing to the purer white of the under parts. There is 
rather more white on the end of the tail feathers, this covering .70 in the 
outer one. 
An immature specimen (26,202) is similar to the adults, but has a little 
more white on the end of the tail, and the feathers of the breast and jugulum 
show triangular spots of brown at the ends. 
Length (of 24,376), 11.75; wing, 4.90; tail, 6.30; graduation, 1.00; Ist 
quill, 1.50; 2d quill, 3.00; bill from nostril, .70; tarsus, 1.51; middle toe 
and claw, 1.22; claw, .35. 
This species is very closely related to the JZ. bahamensis, but 
appears to differ in some appreciable features. The distinction in 
coloration has already been adverted to. It is a larger species, and 
the tail is more graduated—the difference in length between the 
lateral and middle feathers being 1.00 instead of .70. The wings 
are more rounded ; the 5th quill longest instead of the 4th; the 2d 
shorter than the 8th, instead of longer. : 
A larger series of specimens of Jf bahamensis will perhaps be 
necessary fully to ascertain the relationships between the Bahaman 
and Jamaican birds, and prove whether they be really distinet or not. 
How they stand in reference to WM. gundlachi, of Cuba, it is even 
more difficult to determine, as our only guide is the brief comparison 
by Cabanis of his species with I. saturninus of Brazil. To this, 
however, there is very little resemblance on the part of the Jamaican 
and Bahaman birds, as shown by comparing them with a specimen 
presented by the Berlin Museum. Cabanis speaks of the white 
tip of the tail feathers being but 3-4 lines long in gundlachi ; in the 
others it is from one-half to three-quarters of an inch. 
Of the South American Jimi in the museum of the Smithsonian 
Institution, the relationship is closest to I. thenca, of Chile, much 
more than to saturninus. 
Mr. Hill thinks that this species is the Turdus orpheus of Linneus. 
A careful examination, however, of the descriptions of Brown and 
Edwards, upon which the species was founded, will, I think, show 
conclusively that both authors had in view the small Mocking bird 
of Jamaica, rather than the large one.
