62 FUSING. 



Not figured, but compared with Fusus constrictus, Koch, a 

 species which I have placed in the genus Coralliophila (Yol. II, 

 p. 208). It is said to possess a narrower umbilicus and to differ 

 in proportions and somewhat in color. Judging from the 

 description I think it possible that F. Bruijnii belongs also in 

 Coralliophila. 

 F. NIGRIROSTRATUS, E. A. Smith. PL 37, fig. 151. 



Brownish, streaked with darker color between the plications, 

 the revolving lirse whitish, the rostrum purplish black ; aperture 



bluish or purplish within. Length, 50 mill. 



Japan. 



I know nothing of this species beyond the description and 

 figure. 

 F. PHILIPPII, Jonas. PL 38, fig. 152. 



Strigate with brown on a yellowish brown ground ; white 



within. 



Australia. 



This species has not been recognized by local collectors, nor is 

 it found in the Monographies : it is probably not a true Fusus. 



2. Shell with rounded shoulder, no distinct carina. 



This division is made to include a few species, which, so far as 

 our information goes, do not become sharply angulate upon the 

 shoulder ; there is no marked demarkation, however, between it 

 and the preceding group, because some of the latter, normally 

 carinate, vary to rounded whorls without carina. 

 F. NOBILIS, Reeve. PL 38, fig. 153. 



White ; interstices of the ribs faint reddish brown. 



Length, 10-5 inches. 



Hob. unknown. 



Too closely allied to the varieties of F. distans, Lam., having 

 rounded whorls : the only differences being larger size, and per- 

 haps a little more ventricose growth. The specimen figured is the 

 only one known ; a shell sent to me by a London dealer under 

 this name, as from the island of Tortola, West Indies, proving to 

 be identical in all respects with forms of F. distans, var. closer. 

 F. nobilis much resembles F. longissimus, GmeL, also, in size 

 and proportions. 

 F. TURRICULA, Kiener. PL 38, fig. 154. 



Uniform yellowish white. Lentgh, 3*5 to 4'5 inches. 



China.
