PlETEOTOJIA. DISCOES. — PI. IV. fig. 54. 



Fleurotoma testa fusiformi-turritd, spird acuminatd, anfractibus 

 octo, postice tenuissime transversim striatis, medio tuberadatis, 

 ultimo antice striis crassis subtuberculatis instructo ; canali 

 elongato, tenuiter transversim striato ; columelld recta: long. 

 1-8; lot. 0-62, poll. 



A species -which appears to he nearly related to PL catenata f 

 Lam. Desh. II. t. 62, f. 11, 12, 13 (a fossil of the Paris Basin), 

 and which may perhaps he merely a variety of that species. In 

 stature and general characters it resembles it very closely ; its striae 

 are however very different. 



Fusrs begutabis ? — PI. IV. fig. 55. 



A single very imperfect specimen which may probably be a 

 variety of this species. It is not sufficiently complete to allow of 

 its being decided, or of its characters being given. It is not even 

 certain that it belongs to the genus. M. d'Orbigny considers it as 

 a distinct species. 



Navidad, Chile.

Fusus testa turbinate*, antice spiraliter sulcata, spird subdrpresso- 

 conicd, rudi ; anfractibus 3-4, medio tuberculatis, tuberculis 

 transversim sulcatis, in costas subdecurrentibus ; canali elongato, 

 transversim sulcata. 



This somewhat resembles the Triton clavator, Lam. (a recent 

 species), in form ; its spire is however more elevated, and its 

 canal shorter in proportion, I judge it to be a Fasus from the 

 general external appearance, but cannot be quite certain, for the 

 stone about the mouth is so much indurated that it cannot be 

 cleared away. 



Xavidad, Chile.
