118 Mr, Jeflfreys on British Mollusca. 



C. nitidula, iii. 515. Belfast Bay ; very rare. 



C. umbilicata, iii. 519. With the last. 



C. Lajonkaireana. Bulla Lajonkaireana (Basterot), S. Wood, 

 Cr. Moll. p. 178, tab. 21. f. 5 a-c. I found this species at Guernsey, 

 mixed with a dwarf variety of C. obtusa ; but it is rare. Mr. Barlee 

 has also taken it by dredging off Arran Isle, on the Galway coast. 

 The spire is produced and pointed, resembling in this respect Torna- 

 t ell a fascial a ; and the upper lip of the aperture joins the columella 

 considerably lower than in 0. obtusa. It had only been previously 

 known in a fossil state ; and Mr. Wood erroneously referred to it 

 the Bulla mammillata of Philippi, the apex of which is truncated. 

 Dujardin appears to have suggested the affinity of this species to 

 Tornatella. 



Scaphander lignarius, iii. 536 ; var. alba. Zetland ; but rare. 

 Dr. Lukis informs me that the shells of S. lignarius are almost in- 

 variably found broken when they are taken alive, and that the fisher- 

 men think the animal bites off the lip of the shell when it finds itself 

 a prisoner. 



S. zonatus. Bulla zonatUy Turton in Mag. Nat. Hist. vol. vii. 

 p. 352. S. librarius, Lov. p. 10. A young specimen has occurred 

 to me among the Zetland shells, and it exactly corresponds with spe- 

 cimens collected by Mr. M'x\ndrew in Norway. The form is more 

 oval and less oblong than that of a specimen of ^S". lignarius of the 

 same size, the upper lip is rather truncated, and not so acute, and 

 the crown is broader and umbilicated, which last is a character not 

 belonging to the common species. I believe, on reconsideration, that 

 this is Turton' s species, as he distinguished it from the young of 

 S. lignarius by its being of a more conic-oval shape, with the volu- 

 tions more loosely connected, and having the crown umbilicated. 

 The sculpture, however, appears to be the same in both species, as 

 Loven has remarked. In the young of S. lignarius are found the 

 alternate zones and minute granular dots noticed by Turton, but not 

 by Forbes and Hanley ; although these dots are not "raised," as stated 

 by the former : they are, on the contrary, impressed punctures. 

 Unfortunately, Turton' s specimen is in my cabinet at Swansea ; and 

 1 cannot at present compare it with the Zetland and Norwegian 

 shells. 



Philine punctata, iii. 547. Bantry {Rev. Mr. Norman). 

 Pleurobranchus plumula, iii. 559. Bantry {Rev. Mr. Norman). 



Gasteropoda Pulmonifera. 



Limax gagates, iv. 24. Tenby; Torquay; Guernsey; Cumbrae 

 {Rev. Mr. Norman). 



Testacellus Maugei, iv. 28. I found this species, in company 

 with the late Mr. Miller, who was then the curator of the Bristol 

 Institution, about thirty years ago, in Messrs. Miller and Sweet's 

 Nursery Grounds at Clifton ; and it appears to have since become 

 extensively spread and almost naturalized in this country. M. Moquin- 

 Tandon says that it has been found at Dieppe, and he adds that it 

 was probably brought there with some exotic plant. Mr. Norman
