TelUna obliqua, Sow., is a very extreme form of Macoma sahulosn 

 ( = TeUina calcarca, lata, ■proxima, &c.), very abundant in all the 

 English Crags, from the Coralline upwards. The typical form does 

 not occur till higher up in the Crag series, and then but rarely at 

 first. 



Astarte sulcata, DaCosta. — The group for which Dr. Gould suggests 

 the name ictulata is identical with the Astarte OmaVii, La Jonkaire, 

 a very characteristic English and Belgian Crag shell, in which de- 

 posits all the forms mentioned are to be found. 



YoJdia Umatilla, Say, and Y. myaJis, Couthouy. — Dr. Binney is 

 in error in supposing Y. myaJis and Nucida hyperhorea, Loven, to be 

 the same species. The latter is the shell often quoted in European 

 lists as Y. limatala, Say. Both Y. myaJis and hyperhorea are fossils 

 of the English Tertiaries. Y. myaUs and the typical Y. Kmatula are 

 not known as members of the European fauna. Y. hyperhorea is 

 excellently figured in Torell's ' Spitsbergen Mollusker.' 



Margaritana arcuata, Barnes. — I confess I am unable to separate 

 American examples of this shell which have passed through my hands 

 from Unios obtained in different European localities. Like all the 

 freshwater shells, it varies according to circumstances. The same 

 may be said of Anodonta fiuviatiUs. 



Littorina palUata, Say, is probably the same as the Turbo littoralis, 

 Linne, = Z/. limata, Loven. 



Scalaria multistriata, Say. — Under this heading two shells are 

 mentioned, for one of which, if distinct. Prof. Adams has proposed the 

 name S. piilchella. Bivona (1832) has already appropriated the 

 specific appellation (Philippi, En. Moll. Sic. vol. i. t. 10. fig. 1). 



Nassa trivittata, Say, = Nassa {Buc.) projjinqua. Sow. Min. Con. 

 t. 477. f. 2 (1824). — A Crag shell no longer kno^Ti in the European 

 seas. 



Fusus islandicus, Gould (not Chemnitz). — This handsome shell 

 differs in several respects from the type both in form and sculpture, 

 and is the shell which Mr. Jeffreys has proposed to call F. ciirtus, 

 and myself F. americanus (Ann. & Mag. Nat. Hist. Sept. 1870). 

 This is another of the English Tertiary shells no longer found living 

 in European waters.

Gentlemex, — Please add to my paper as a note, or, if too late, as 

 an addendum in your miscellaneous articles : — 



" The bodies described by Hering as the testes agree in number 

 and position with those I have seen ; but he does not give illustra- 

 tions of their microscopical structure.
