FUSING. 67 



F. HEMIFUSUS, Kobelt. PL 58, fig. 397. 



Locality unknown. 



This species, published in the Conchylien Cabinet in 1880, came 

 to me too late to insert in its proper position in the genus Fusus. 

 It is precisely like F. coins, var. Brenchlyi, and is therefore a 

 synonym. 



F. LINEOLATUS, Costa. This is evidently not a Fusus. It is said 

 to inhabit the Mediterranean Sea, but I do not find it in Wein- 

 kauff or Monterosato. 



F. PUSILLUS, Pfeiffer. Probably a very young shell, if a Fiisus, 

 as it only measures two lines in length. It has not been recog- 

 nized. 



West Indies. 



F. APERTUS, Carpenter. " The six specimens found of this spe- 

 cies were either young or fragmentary." The length of the 

 shell is one-tenth of an inch ! Why will naturalists cumber the 

 nomenclature with species founded upon such insufficient ma- 

 terial ? 



F. MODESTUS, Gould. An unfigured shell, collected by the North 

 Pacific Expl. Exped. in ten fathoms, shelly sand, at Hakodadi, 

 Japan. The description is useless for recognition of the species, 

 and the types were destroyed, I presume, in the great Chicago 

 fire. 



F. GILVUS, Phil. This may be a Hemifusus, as there is a per- 

 forate umbilicus. The species is from China, and has not been 

 figured. 



F. OBSCURUS, Phil. PI. 40, fig. 176. 



Nearl}' black, the upper part of the whorls, the keel, the 

 tubercles and a central band on the last whorl are lighter. 



Length, 1-65 inches. 



Hob. unknown. 



The color, the flexure of the coluniella, etc., are not typical of 

 the genus, and would indicate some relationship to the Perister- 

 niinse: there is no mention made of columellar plaits, however. 

 Is this possibly a discolored fossil ? 



F. NUCLEUS, Brod. PI. 40, fig. 187. 



Whitish. Length -5, lat. *33 inch. 



Galapagos.
