collected during the voyage of the St. George. In 1930 Li^^ published 

 a paper in which he described several new species from a mixture of 

 Miocene and Recent shells dredged in Panama Bay. Pilsbry^i reviewed 

 Li's paper and from a study of the collection concluded that only 8 of 

 the species cited by Li were Miocene forms and the remainder were 

 Recent shells from Panama Bay. In this paper Pilsbry described several 

 new species. The following year Pilsbry and Lowe^^ published a paper 

 dealing chiefly with west Mexican and Central American mollusks. In 

 this paper many species were cited from Panama and several new species 

 were described from there. In a recent paper several new species from 

 the Panamic Province were described by Pilsbry and Olsson.^^ Mollusks 

 from Cocos Island some 300 miles northwest of Panama City have been 

 listed by Biolley,!^ Pilsbry and Vanatta,i^ Da.11,^^ and Hertlein.^''' 

 The Recent Pectinidae in the collections secured by the Templeton 

 Crocker Expedition to the Galapagos Islands were described by Hert- 

 lein.^^ These included 3 species of Pecten collected by Hertlein at 

 Panama during the Allan Hancock Expedition to the Galapagos Islands. 

 The Gulf of Panama lies well within the tropics in 7° to 8° north 

 latitude and contains a tropical marine fauna. In it dwell such tropical
