14 SIMPULUM. 



T. LINEATUS, Brocl. PL 8, fig. 51. 



Yellowish brown, the raised revolving lines chestnut-brown ; 

 columella and aperture chocolate, the plications white. 



Length, 2'25 inches. 



Galapagos Isles, iu sand ; 6 fathoms. 



T. GRANULATUS, 1) linker. 



An unfigiired species, 35 mill, in length, from Bass' Straits, 

 Australia. Said to belong to the group Simpulum. I cannot 

 it. 



T. CONTABULATUS, Alltoil. 



Unfigured and not identified ; placed by the author in his 

 "jrileare" group. 



T. LIROSTOMUS ^ Described by Mr. Arthur Adams in Ann. Mag. 

 T PAPILLOSUS Nat. Hist. 1870. All from Japan. No figures. 

 T TRING\ f dimensions, nor comparative characters are 



T. NODILIRATUS given ; so that I am unable to give an opinion 

 as to their novelty. 





# * # Group Linatella, Morch. r 



The species of this group approach more nearly to the Doliidae 

 in form and sculpture than any other Tritons. 



T. TRANQUEBARICUS, Lain. PI. 8, figs. 52, 53. 



Light yellowish brown, the revolving ridges chocolate-brown ; 

 whitish within. Length, 1'25 to 2 inches. 



W. Coast Africa ; West Indies. 

 T. POULSENII, Morch. PI. 8, fig. 54. 



Thin, inflated, orange-brown; white within the aperture; lip- 

 teeth orange color. Length, 2 inches. 



West Indies. 



Two specimens in the Swift Cabinet (Mus. Philad. Acad.). It 

 is possibly a variety of T. cingulatus, although much more 

 inflated and with shorter canal than the typical form of that 

 species. Very much like the genus Dolium in its general 

 appearance.
