Family CORVIDAE 



XANTHOURA YNCAS LUXUOSA (Lesson; 



Garrulus luwuosus Lesson, Rev. Zool., Apr. 1839, p. 100 (Mexico). 



The green jay was noted only in the Sierra de Tuxtla, where 

 Carriker shot a male and saw another bird on May 19 on Cerro de 

 Tuxtla, and secured a pair on April 22 and a male on April 23 on 

 Volcan San Martin, between 2,500 and 3,500 feet elevation. There are 

 specimens in the National Museum taken by Nelson and Goldman at 

 Catemaco on May 5 and at San Andres Tuxtla on May 10, 1891, and by 

 A. E. Colburn at Paso Nuevo, April 22, 1901. 



The seven specimens listed are so definitely intermediate that they 

 arc cited under the name luxuosa only because there is a very slight 

 preponderance of their characters toward that race. With luxuosa 

 they agree in size, including especially the bill and length of wing, 

 and in the restricted amount of white on the forehead. Actually they 

 look very similar to vivida with which they agree in brighter, more 

 yellowish coloration of the ventral surface, the under tail coverts 

 especially being yellow with only a slight wash of green. True vivida, 

 however, is larger and has more white on the forehead. The southern 

 Veracruz birds thus appear intermediate between the race named 

 centralis and its slightly differentiated ally maya of van Rossem, 50 

 which have clear yellow underparts, with little or no green, that color, 

 where present, being confined to the sides, and true luxuosa of farther 

 north. The characters found do not warrant separation of the series 

 from the Tuxtla area under a distinct name. 



PSILORHINUS MORIO MORIO (Wagler) 

 Pica Morio Wagler, Isis, 1829, p. 751 (Veracruz, Mexico). 



Called pepe universally like the related species, this great jay, 

 marked by its uniform color without the white tips on the tail, ranged 

 everywhere through groves and woodlands around Tres Zapotes. The 

 two species were found often in company and were about equally 

 common. The three skins preserved were taken on March 28 and 

 April 3, 1939, and February 24, 1940. These have the duller colora- 

 tion of the southern race. Hellmayr, in the reference cited under 

 P. m. mexicanus, groups all these jays under the name morio. From 

 Nuevo Leon and Tamaulipas south into Chiapas and Tabasco these 

 birds present an unbroken series, specimens from the north being pale 

 and those from the south dark. Differences between the extreme 

 north and the south are striking, and the distinctions are definitely 

 joined with geographic distribution. It appears to me proper to
