Nassa densecostata, A. Bell. Ann. and Mag. Nat. Hist, May, 1871. 



Locality. Cor. Crag, near Orford. 



A single specimen, not perfect, has been put into my hands for figuring. This came, 

 Mr. A. Bell informs me, from the Coralline Crag, near Orford. Its nearest resemblance is 

 to N. limata, Ch. (B. prismaticum, Broc), but is much more slender and more numerously 

 costated, as pointed out by Mr. Bell. I have seen only this specimen, and its specific 

 distinction will require some further evidence for its confirmation. 



Nassa propinqua, J. Sowerby. Crag Moll., vol. i, p. 30, Tab. Ill, fig. 2. 



Localities. Red Crag, Walton Naze, and Sutton ; Chillesford bed, Easton Bavent. 



This shell Mr. Bell gives ('Ann. and Mag. Nat. Hist.,' September, 1870) from the 

 Chillesford shell-bed of Easton Bavent Cliff, but I have not seen the specimen. He says 

 it is the same as N. trivittata, Say., Buc. trivittatvm, Gould (1st ed., ' Inv. Massach.,' 

 p. 309, fig. 211, and in 2nd ed., p. 364, fig. 632), neither of which figures well represent 

 the Crag shell, but the recent species is said to be very variable. This name {N. propinqua) 

 was given to me in MS. by S. P. Woodward as from the Cor. Crag (in Mr. Wigham's 

 collection), but I have not been able to find the specimen. Sowerby's name has, I believe, 

 priority over that of trivittata.

 intus, dentato. 



Ascis, \ an inch. 



Localities. Coralline Crag, near Orford. Red Crag, Waldringfield {Bell). 



The specimen figured was obtained by Mr. Bell from the Cor. Crag, near Orford, and 

 it was put into my hands with the name of N. pulchella, and it is the shell described under 

 that name in the ' Ann. and Mag. Nat. Hist.,' May, 1871, as N. pulchella, A. Bell, n. s.,
