LEPTOTILA VERREAUXI RIOTTEI (Lawrence).

 cinnamon-drab to fawn* color.

 men, 17; tarsus, 29.5; middle toe, 24. '^

LEPTOTILA VERREAUXI NUTTINGI Ridgway. 



OMETEPE DOVE. 



Similar to L. v. verreauxi but with much less of vinaceous-russet 

 (or cacao brown) on inner webs of remiges, this color forming merely 

 a broad edging, at the widest part not more than one-fourth the width 

 of the web; upper parts browner (but much lighter brown than in 

 L. V. riottei). 



Adult male. — Length (skin), 260; wing, 141; tail, 107; exposed cul- 

 men, 15; tarsus, 30.5; middle toe, 24.5.'' 



Adult female. — Length (skm), 260; wing, 147.5; tail, 104; exposed 

 culmen, 17.5; tarsus, 31; middle toe, 25. ^ 



In the coloration of the inner webs of the remiges this form is pre- 

 cisely intermediate between L. verreauxi and L. fulviventris; since, 

 however, specimens of the latter from northern Nicaragua have no 

 more of the cinnamomeous or vinaceous coloring on the inner webs 

 of the remiges than those from extreme northern localities, actual 

 intergradation, while not improbable, is by no means proven. In 



O' One specimen (the type), from Navarro, on the Caribbean slope. Only one other 

 example seen by me; tliis being a specimen collected by Boucard, but without 

 locality and with sex undetermined. 



^According to Carriker, Bellavista is another name for Agua Caliente (sometimes 

 called Hervidero), "a small village, situated on a river of the same name [Agua Cali- 

 ente], about 4 miles south of Cartago, and at a considerably lower altitude (about 

 3,800 feet) . " I have not seen a specimen of this species from Agua Caliente, but think 

 that specimens from that altitude on the Caribbean slope probably represent this 

 form. Navarro, the type locality, is "on the Caribbean slope," south of the Rio 

 Reventazon, "at an altitude of probably 2,500 to 3,000 feet."
