Fossil. Pliocene : Yal di Andona (Brocchi) ; Coralline Crag 

 (S. V. Wood); Monte Mario (Conti, Rigacci)\ Eicarazzi {Monte - 

 rosato)\ 



An allied species from the Korean dredgings (35 fathoms) is of 

 a rhomboidal shape and more solid and it has a sharper keel 

 and transverse strise or riblets. Arcinella Icevis of Philippi, a 

 Sicilian fossil, is perhaps mj Decipula ovata from the ' Porcupine ' 

 dredgings of 1869, and from Osterfiord in Norway, as well as the 

 Tellimya ovalis of Prof. G. O. Sars from the LofToden Isles. See 

 Friele, ' Bidrag til Yestlandets Molluskfauna,' in Yidensk. Forh. 

 for 1875 ; and Sars, ' Bidrag til Kundskaben om Norges arktiske 

 fauna,' 1, Mollusca (1878), Suppl. p. 341, t. 33. f. 1, a-c.

Hal. Korea, 30-54 fathoms; young. Apparently world-wide 

 in its distribution, from low water to 1G22 fathoms. 



Fossil. Miocene, Pliocene, and Post-tertiary, throughout Europe 

 (including the Coralline Crag), Northern Asia, and N.E. America. 



Synonyms, both generic and specific, numerous.

Hah. Korea, 30-54 fathoms ; var. princeps, young. Type and 

 variety : from Greenland and Wellington Channel southwards to 

 Cape Cod, and from Spitzbergen to the Strait of Gibraltar ; Sea 

 of Okhotsk and North Japan: 4-250 fathoms. 'Lightning' 

 Exped., 170 and 189 fathoms. ' Porcupine ' Exped., 1869, 73-420 

 fathoms ; 1870, 292-1095 fathoms. 



Fossil. Miocene (?), Pliocene, and Quaternary or Post-tertiary 

 formations, in Scandinavia, Great Britain, and Sicily ; mostly in 

 glacial " deposits. 



As usual in the case of tolerably common species like this, P. 

 noachina has received several other names. 



Attached to a living specimen of P. noachina from 420 fathoms 

 in the first ' Porcupine ' Expedition was a Planorhulina (one of 

 the Eoraminifera) of the same kind that has occurred in the Korean 

 dredgings. Mr. H. B. Brady tells me that this Planorhulina
