NO. 2207. WEST AMERICAN MELANELLID MOLLUSKS—BARTSCH. 299 



De Folin unfortunately cites as type-locality for all the shells 

 described in this paper two places — one the environs of Negritos 

 (which may mean Negros Island, Philippines), and the other Isle 

 aux Pcrles — i. e., Margarita Island, Bay of Panama. In order not 

 to miss any West iVmerican members, I have quoted all the described 

 forms. 



In 1878 G. B, Sowcrby published his Monograph on the genus 

 StyVfer} In this he redescribes and figures plate 1, figure 3, Styhfer 

 astericola Broderip. 



Six years later G. B. Sowerby's Monograph on the genus Stylifer 

 appeared.^ In this we find Stylifer astericolus Broderip described 

 on page 159 and figured on plate 479, figures 4 and 5. 



Two years later Tryon, in his Manual, reached our family.' 

 Besides giving a treatment of the superspecific groups he describes 

 and figures ail those previously figured. He also gives figures of 

 such as he had represented in his collection and he cites all those 

 known to him to date. From the West Coast of -Vmerica the follow- 

 ing are listed :
