Mr. Jeffreys on British MoUusca. 129 



O. acuta, iii. 269. Mr. M'Andrew has taken this species in Nor- 

 way with O. insculjita. 



O. pUcata, iii. 2/1. Guernsey. 



O. EuHmoides, iii. 273. A comparison of fresh specimens just 

 received from Mr. Barlee, of what I considered at first a distinct 

 species, and named O. notata, has satisfied me that the latter is only 

 a variety of this Protean species. 



O. dubia, iii. 27G. Guernsey. 



O. alba, iii. 2/8, var. gracilior et scalarlformis. Guernsey, Skye, 

 and Zetland {Mr. Barlee & J. G. J.). 



O. cylindrica, iii. 287. Torbay. 



O. insculpta, iii. 289. Guernsey. 



O. Warrenii, iii. 292. With the last. 



O. truncatula, iii. 294. Adult specimens have a prominent and 

 sharp tooth on the columella ; but it is scarcely visible from the out- 

 side of the aperture. 



O. decussata, iii. 303. With the last. 



Eulimella Scillse, iii. 309. Torbay {Dr. Battershy). 



E. acicula, iii. 311. Guernsey {Br. Lnkis & J. G. J.). 



E. atfinis, iii. 313. Torbay {Dr. Battershy). Mr. M'Andrew 

 has taken it in Norway with E. acicula. 



Otina Otis, iii. 321. var. alba. Guernsey (Dr. Ln/iis). Dr. Gray 

 has very properly placed this genus in the family of JuricaladcB, to 

 which it has conchological as well as malacological relations. 



Cerithiopsis tubercularis, iii. 36."), {tuLerculare) var. alba. Ply- 

 mouth {Mr. Barlee). 



C. Clarkii, iii. 368. Another (being the second) specimen of this 

 remarkable shell has occurred to me in dredged sand from Guernsey 

 with C. tubercularis, which is not uncommon there ; and it confirms 

 the suggestion of the authors of the ' British MoUusca,' that it might 

 prove to be a distinct species. Besides having only two rows of 

 tubercles, the volutions are scalariform, and the suture is much deeper 

 than in C. tubercularis. 



C. pulchella, n. s. PI. V. fig. 8 a-c. 



Testa cylindrica, solidula, rufescente, costis longitudinalibus 18-20, 

 transversis 4, cancellata, quarum 2 mediae longinque prominent ct 

 infima carinam simulat, ad juncturam tubcrculos cfformantibus ; 

 anfractibus 7, convexis, ultimo rcliquos subaequante ; sutura pro- 

 funda ; apertura ovata ; canali brcvissimo ; operculo membranaceo ; 

 long. Jj, lat. Jj unc. 



Falmouth, Plymouth, and Guernsey ; but rare. Although the 

 C. tubercularis is very varial)lc in size, this species has a peculiar 

 aspect, which is unmistakeable for that of any variety of the last- 

 named species. Specimens of that species, of the same size as C. 

 pulchella, have no less than twelve volutions ; and the cancellations 

 are invariably closer, and the transverse rows of tubercles equally 

 prominent.
