BIRDS OF SOUTHERN VERACRUZ — WETMORE 319 



brighter red of the breast and abdomen, the less extensive white of the 

 under tail-coverts, and in the length of the tail, which is shorter than the 

 wing instead of the reverse. In three males the average length of the 

 wing is 66.7 and the tail 64.2 mm., and in one female these dimensions 

 are 62.4 and 61.5 mm., respectively. 



BASILEUTERUS CULICIVORUS CULICIVORUS (Lichtenstein) 



Sylvia culicivora Lichtenstein, Preis-Verzeichniss mexicanischer Vogel, 1830, 

 p. 2 (Jalapa, Veracruz). 



Carriker found this warbler to be one of the most common birds on 

 Cerro de Tuxtla, where he secured specimens on March 11, 19, and 29, 

 April 1, 3, and 9, and May 6, 1940. It was found mainly above 1,000 

 feet elevation, ranging in the undergrowth and lower trees. In the 

 lowlands it is a straggler, as Carriker secured one near Tlacotalpam on 

 February 7 and one at Tres Zapotes on January 26. 



BASILEUTERUS BELLI SCITULUS Nelson 



Basileuterus belli scitulus Nelson, Auk, 1900, p. 268 (Todos Santos, Huehue- 

 tenango, Guatemala). 



Carriker secured two males and a female on the higher slopes of 

 Volcan San Martin on April 20 and 22, 1940. They were found from 

 3,500 feet elevation to near the summit, in undergrowth and the smaller 

 trees of the forest. 



These birds are listed here under the name scitulus though with 

 more material the birds of Volcan San Martin may prove distinct. 

 They are definitely darker above than B. b. belli, agreeing in this with 

 scitulus, but appear slightly smaller, the wing in the two males being 

 56.3 and 57 mm. and in the female 53.2, dimensions that are within the 

 lower limits of the other forms. This is another case where a species 

 from this mountain shows affinity with mountain forms of Chiapas 

 and Guatemala rather than with those of the Mexican tableland proper. 



BASILEUTERUS RUFIFRONS SALVINI Cherrie

 (Coban, Vera Paz, Guatemala). 



Specimens were obtained at Tres Zapotes, March 24 and 28 and April 

 6, 1939, and January 20 and April 5 and 8, 1940 ; Tapacoyan, May 5, 

 1940; on Cerro de Tuxtla, May 4, 1940; and on Volcan San Martin, 

 April 21, 1940. In the mountains they occurred to 3,000 feet elevation. 

 They range in thickets, keeping well under cover and occasionally 

 venturing out into growths of weeds. On April 6 I shot a breeding 

 pair, and on April 9 I saw two more that were obviously mated. 



All these birds have the abdomen partly yellow, this condition 

 ranging from a faint wash to a condition of quite solid color. They
