Measurements. —Male,* winoj 145 mtn., tail IIH, tarsus 43, middle toe 
with claw 34, exposed cnlmen Id, culinen from cere 10.8. 
Geographical distribution. —Porto Pdco (iMaricao, on western end of the 
island, elevation 1500 feet). 
Remarks. —The single specimen upon which this description is based 
constitutes the only record of this genus in Porto Rico. One other bird 
was seen in the same locality but was not secured. 
In studying this bird I have l)eeu able to bring together the following 
material: three specimens from San Domingo, an adult and an immature 
male and an adult female ; and an adult and an immature male from Cuba. 
The birds from Cuba and San Domingo until now have been considered 
the same, though I do not believe that they have been critically compared 
l^efore. For many years tliey were known collectively as Accipiter 
fringilloides Vigors, described in 1827.t 
Recently Mr. J. H. Riley + called attention to the fact that this was 
antedated by Accipiter striatus Vieillot § so that for four years they have 
borne this name. As might have been expected, on careful examination 
the birds from Cuba and San Domingo are found to be distinct forms so 
that now the following three subspecies may l)e recognized; 
Accipiter striatus striatus Vieillot, San Domingo (Honduras, Catare, 
and Miranda in San Domingo; Recoup near Port au Prince, Haiti). 
Accipiter striatus fringilloides Vigors, Cuba (Guantanamo, Guama, 
San Diego de los Banos, Bayamo). 
Accipiter striatus Venator 'Wetmore, Porto Rico (Maricao). 
The characters of these three forms may be conveniently expressed by 
means of the following key; 
a. Deep neutral gray above; abdomen white; thighs white, faintly 
barred with mouse gray; no concealed white spot on inner tertials; 
sides of upper breast rood’s brown; forehead distinctly tinged 
with hazel. 
Accipiter striatus fringilloides. 
aa. Dark or dusky neutral gray above; center of abdomen white, sides 
barred with brown ; thighs white, heavily barred with hazel or 
pecan brown mixed with dark purplish gray; a large concealed 
white spot on three inner tertials on each side; sides of upper 
breast hazel; no hazel on forehead. 
b. Dark neutral gray above; upper side of tail with dark bars 
indistinct; black shaft marks of feathers on underside less 
distinct; thighs barred with pecan brown intermixed with 
distinct dark purplish gray. 
Accipiter striatus striatus. 
bb. Dusky neutral gray above; upper side of tail with sharply 
defined black bars; black shaft marks of feathers under¬ 
neath strongly defined; thighs hazel barred with white. 
Accipiter striatus Venator.
