Appendix to Part II 617 



The shell to which this hears the greatest resemhlance is a fossil 

 named Fasciolaria Burdigalensis, Defr. by De Bastoret in the 

 ' Alemoires de la Soc. d'Hist. Nat. de Paris ; ' in our shell there is, 

 however, no appearance of oblique folds on the anterior part of the 

 columella, consequently it is generically distinct ; while in other 

 respects it is sufficiently different, as may be seen by comparison. 

 Its spire is longer in proportion to the last volution, and its canal 

 shorter. 



Navidad, Chile. 



Fusrs Noachi^us. — PL IV. figs. 58, 59. 



Fusus testa ovato-fusiformi, utrdqwe subacuminatd, csquali, an- 

 jraetibus quinque spiraliter sulcatis, svlcis plerumque seriatim 

 2)ertusis ; posticis longitudinaliter obtuse costatis ; canali me- 

 diocri, subascendente ; suturd distinctd. 



A species which bears some resemblance to Fusus Noce, Lam. ; 

 still it is not nearly related to that species. In shape it resembles 

 F. lamellosus, to which it is really related, but it is quite destitute 

 of the lamellar varices, so that it may easily be distinguished. 



San Julian, Patagonia. 



FT7STTS PATAG027ICTTS. — PL IV. fig. 60. 



Fusus testa ovato-oblongd, tenuiusculd, multifariam varicosd, an~ 

 fractibus postice angulatis; varicibus lamelliformibus, antice 

 deflexis, postice acuminatis, interstitiis transversim sulcatis ; 

 aperturd subcirculari, canali breviusculo, umbilico valido. 



Nearly related to Fusus lamellosus and F. Magellanicus, and 

 apparently connecting the two. 



Pyrttla dista^s. — PL IV. fig. 61. 



Pyrula testa Jiciformi, tenuiusculd, spird brevissimd obtusd, anfrac- 

 tibus quatuor, ultimo tnaximo, decussatim striato, et carina to, 

 carinis 11—12, distant ibus, nonnullis interstitialibus minus 

 elevalis : long. 1*8; lat. 1*2, poll. 



A very elegant species of true Pyrula, somewhat resembling 

 P. nexilis (a tertiary fossil) in general appearance, but differing 

 from that species in its proportions, being much wider in com- 

 parison with its length, and having a much shorter spire. 



Navidad, Chile.
