52 Ft^SIN^. 



A rare species, iiihahitiug- deep waters. It is found fossil in 

 the miocene and pliocene of the adjacent countries. 



h. Tubercles compressed ; not ribbed. 

 P. PROBOSciDiFERUS, Lam. PI. 82, fig. '.IS. 



Yellowish brown, covered by a light biown epidennis. 



Length, 8 to 12 inches. 



Audralia. 



This species is remarkable for its shelving shoulder, forming 

 a conical spire with flat sides, for the ridge at the angle of the 

 shoulder, which on the body whorl is onl^^ slightly or not at all 

 tuberculate, for the absence of longitndinal ribs, and for the sepa- 

 ration of the lip from the canal, forming a long, narrow, uml)ili- 

 cal channel. It is an aberrant form which I have been tempted 

 to place in Hemiftiftus, or to make it the type of a new genus. 

 Dr. Tiinney identified this s[)ecies with Mnrcx Aruaitus^ Linn., 

 which is exceedingly (piestional)le, as that name is usually cited 

 for a veiy different shell belonging to the genus Fulgur. It 

 appears to me to be more advisable to retain Tjamarek's well- 

 known name. 



F. VENTRicosus, II. Adams. PI. 32, fig. 94. 



Yellowish white. Length, 130 mill. 



D'AguUias Bank, Gape of Good Hope. 



Evidently related to the preceding species and showiug even 

 more clearly than it does the separation of the inner lip from 

 the columella. Kobelt has changed the name to Adamxii^ because 

 the original specific name is preoccupied l)y Beck and Gray, but 

 as I do not adojit either of these in the genus, I retain Adams' 

 designation. 



c. Tubercles compressed, shell ribbed longitudinally. 

 F. COLLS, Linn. PI. 32, figs. 89-92. 95. 



White, the upper whorls of the spire and a part of the canal 

 stained with brown ; i)eriphery sometimes brown-banded between 

 the nodules. Length. 6 to 7 incthes ; diameter 1-5 inches. 



Ceylon, Tonga Tabou. 



Var. TOREUMA, Martyn (fig. 95), is distinguished from the 

 typical form only by being more higldy colored. 'I'he shell is 

 yellowish bi-own, with chestnut-brown between the tubercles on
