30 ARKIV FÖR ZOOLOGI. BAND 13. N:0 4. 



In the populär account of his travels Dr. Bovallius says, 

 that he in Pedro Gonzalez met with flocks of « small graceful 

 döves, not bigger than a house-sparrow». In a foot-note he 

 indicates them as Chamcepelia passerina. He observed them 

 in the few open places in the island; they were, however, very 

 shy and disappeared at his approach into the bushes. As he 

 therefore brought no skins of this supposed Ground Döve, it is 

 impossible to verify his statement. The occurrence of Ch. 

 passerina in the islands would be very interesting, but I sup- 

 pose, that in reality it dealtes with Ch. rufipennis rujipennis.

Thayer and Bångs say that if it should be found ne- 

 cessary to recognize the Central American form as L. v. riottei 

 Lawr., the Pearl Islands bird is to be included with true L. 

 verreauxi of South America. Mr. Ridgway, however, found 

 the range of the typical L. v. verreauxi extending över Central 

 America up to the extreme southwestern corner of Nicaragua. 



The present specimens agree with the typical form. The 

 measurements of the male are as follows: wing 141, tail 116,5, 

 exp. culmen 15, tarsus 25,5, middle toe 24,5 mm.
