penter^ in several papers added many species to the known fauna of 

 Panamanian mollusks. De Folin^ published three volumes, now rather 

 rare, which included descriptions of a number of species, mostly small 

 gastropods, from Panama. Dall^ in 1908 published a report describing 

 the mollusks dredged by the U. S. Fish Commission Steamer Albatross. 

 In this paper he described many new species from Panama and also cited 

 many other species from that region. The following year the same author 

 published an excellent paper on the marine mollusks of Peru^ in which 

 he cited and gave references to many species known to occur at Panama. 

 Dall and Bartsch*^ in 1909 described and figured many species of 

 the Pyramidellid mollusks from western North America, including those 

 known to them from Panama. Zetek^ in 1918 published a paper listing 

 the marine mollusks of Panama and mentioned their distribution and 

 synonymy. Olsson^ in 1924 cited a number of marine mollusks from 

 Peru and Ecuador, many of which also occur in Panamanian waters. 

 Tomlin^ in 1928 cited a number of species from Panama which were
