C H. Lankester Collection : Mouth of Matina River. 



A rare inhabitant of the lagoons and sluggish rivers on both the 

 Caribbean and Pacific lowlands. Few specimens have been recorded 

 and I never saw the birds alive in that country, although I quite 

 thoroughly searched the lagoons about the mouth of the Matina River 

 where Mr. Lankester secured his bird the previous year.

S. leucogastra is the Booby found along the Caribbean coast. The 

 only locality where it occurs along the eastern coast of Costa Rica is 

 in the vicinity of Port Limon. A large colony is resident on the 

 Island of Uvita in Port Limon Harbor, while two small rocky islets 

 off the mouth of the Moin River, a short distance up the coast, have 

 other colonies. I never saw them anywhere south of Limon, between 

 that point and Boca del Toro, Panama.
