Fusus. 375 



curved. Length, two and a half inches; breadth, one and one fourth 

 inches ; divergence, fifty degrees 



From the Bank Fisheries. Taken from codfisli. Several good 

 specimens of various ages are now before me, for most of which I 

 am indebted to the kindness of Colonel Totten. St. Anne {Bell) ; 

 fossil, ^lontreal {Dau'son). 



This shell is undescribed, unless it be the much debated and 

 equivocal Marex despectus of Linnteus, about which British writers 

 seem to have been so much puzzled. It differs from the early state 

 of the FusKS antiguus of Linnceus, the F. despectus of most British 

 conchologists, in the more rounded form of the whorls, and in being 

 destitute of the network formed Ijy the close revolving and longitu- 

 dinal striae, and it would evidently never assume the appearance of 

 a mature F. aniiquus. 



The only figures I have seen at all resembling this are figure 

 1295 of Martini, which he regards as a variety of Murex aniiquus, 

 as indeed he does the M. despectus of Linnceus also ; and the 

 figure of Donovan in his " British Shells," Vol. V. pi. 180, under 

 the name of Murex despectus. I have very little doubt that it 

 is the genuine M. despectus of Linneeus ; but as another shell is 

 now universally received under that name, it seems the most ju- 

 dicious way to ap})ly a new name to this, with the above explana- 

 tion. 



This shell probably never becomes three inches in length. It is 

 inelegant and coarse, in general smooth and somewhat shining, 

 though seeming to be made up of small, plane surfaces, rather than 

 curved ones. The elevated lines are broad, and smoothly rounded, 

 of a darker color than the rest of the shell, and give it an appear- 

 ance as though it might have been turned in a lathe, but left in an 

 unfinished state. In general outline it very strongly resembles the 

 fossil F. conlrarius of the English crag formation. 



Pusus decemcostatus. 



Fig. 202. 



Shell oval, turreted, ash colored, with ten elevated, rounded, horn colored ribs 

 on the lower whorl, and two on the upper ones.
