544 NOTES ON COSTA KICAN BIRDS. 





Single male from Costa Rica, has the dull yellowish orange flecks on 

 the crown larger, ami the stripes on the sides, etc., narrower and more 

 distinct, thus showing a departure toward the characters of the Colom- 

 bian form and suggesting possible inosculation of the two types. 



Myiopsitta lineola (Cass.). 



An adult male from Naranjo de Cartago (No. 1819, coll. National 

 Museum of Costa Rica, August, 188G, J. Cooper), agrees closely with 

 specimens from Southern Mexico.* 



Mimus gilvus, ViEILL. 



An adult from Costa Rica (E Zarcero, alt. 7,000 ft., March 1, 1887; 

 Jose C. Zeledou), in the collection of the Costa ltica National Museum 

 (No. 893), exactly resembles in coloration an adult male from Bogota 

 (U. S. Nat. Mus., No. 32G91), its measurements being as follows : Length 

 (skin), 9.70; wing, 1.70; tail (feathers worn at tips), 4.90; exposed call 

 men, .80; tarsus, 1.35; middle toe, .95. 



Carpodectes nitidus Salv. 



Immature male (No. 1509, coll. National Museum of Costa ltica, 

 Pacuare, Costa Rica, 1870; Carlos Cervantes).— Similar to the adult 

 male, but terminal third, or more, of five outer primaries and greater 

 portion of the others, slate-dusky; three or four innermost secondaries 

 also marked medially with the same color, which prevails on the last, or 

 terminal half; primary coverts and alulae also mottled with dusky. 

 Length (skin), 8.50; wing, 5.50; tail, 2.90; exposed culmeu, .72; tar- 

 sus, .95. 



Dendroniis punctigula, sp. nov. 



Sp. Char.— Similar in general coloration to I), triangularis (Lafk,), 

 but throat spotted instead of squamated, and rump chestnut instead 

 of olive, as in I), crythrojnjgia; differing from the latter in much more 

 olivaceous coloration, narrow streaks instead of ovate spots on back, 

 longer bill, and other characters. 



Hah. — Costa Rica and Veragua. 



Adult male (type, No. 115040, Naranjo, Costa Rica, Aug., 18G6; J. J. 

 Cooper).— Pileum deep olive, most of the feathers with very narrow and 

 indistinct shaft-streaks of buff; hind-neck, back, and scapulars, brown- 

 ish olive (approaching raw umber), the back with mostly narrow and 

 concealed streaks of pale buff; lesser and middle wing-coverts similar 

 to the scapulars, but browner; greater coverts light olive or hair- 

 brown; secondaries, and about the basal half of inner webs of primaries 



k A South American form— Myiopsitta lineola tigrina (SouANCti)— is readily disti J 

 guishable by the following characteristics: 



Myiopsitta tigrina Souanck, Rev. et Mag. de Zool., 1656, 141 (Venezuela). 



Similar t<> M. lineola (Cass.), but rather larger, brighter and darker in color, with 

 black markings on wings, ramp, upper tail-coverts, and tail much heavier. {Of.
