 pcnita, n.sp. ; Bullina petrosa, n.sp. ; Pyrula modesta, n.sp. ; Fusus

The following species were collected by the writer at Astoria, and 

 sent to the American Museum at New York. As the list is unpub- 

 lished, it may be well to include it as a note to Mr. Conrad's paper : 

 yucula divaricata, Con. ; ^. imprcssa, Con. ; Tellina alharia, Con. ; 

 Solemya vcntricosa, Con.; Pecten propatulus, Con.; Area devincta, 

 Con.; \'<')nis hisecta, Con.; Pectunctilus nitcnfi, Con.; Venus an- 

 gui^li Irons. Con. ; Tellina emacerata, Con. ; T. arctata, Con. ; Lucina 

 aculitmeata. Con. ; Cardita snhlenta, Con. ; Terebratnla nitcns, 

 Con. ; Dolium petrosiiim, Con. ; Rostellaria indurata, Con. ; Fusns 

 geniculus; Sigeretus (Lumatia) scopulosa; Teredo suhstriatus; A. 

 dentalium; NauUtus angulatus, Con. Besides these there are three 

 or four species of bivalves and four of Gasteropods, undetermined, 

 and one Brachiopod. These fossils were collected from the cement 

 stones and argillaceous shales ; all belong to one geological period, 

 as -the same species are found in each to some extent, though most 

 are different.
