fathoms water Loch Fyne. Three specimens were found, one 

 alive and in fine condition. Mr. Barlee has since dredged 

 a single example in the same locality. A comparison 

 of British specimens with those of Neara sulcata, sent 

 from Sweden by Professor Loven, and now in the cabinets 

 of Mr. Hanley and Mr. Cuming, has proved the identity of 

 the species, and examples from the ^gean, where it was 

 first discovered in a living state by one of the authors, who 

 found it not uncommon, living in various depths of water, 

 through the great range of from 20 to 185 fathoms, agree 

 equally well. The shell varies not a little in shape, and 

 the Mediterranean specimens are usually intermediate in 

 character between those of Norway and of our own seas. 

 The species was originally described and figured by Des- 

 hayes from fossil examples brought to France from the 

 tertiaries of Greece. His figures agree well with the i-e- 

 cent shell, but that figured by Philippi (Enum. Moll. 

 Sicil. V. ii. p. 13, pi. 13, f. 9), is too doubtful to permit of 

 our quoting it as a synonym. Some species of Neecra in 

 the Curaingian cabinet, chiefly from the Indian seas, come 

 remarkably near Necera costellata, especially N. concimia, 

 Gouldiana, and Singaporensis.

In general shape and appearance this, our smallest 

 NcfBra, bears no inconsideiable resemblance to the young of 

 cuspiclata, but is easily recognised by the linear elevation
