BUCCINUM. 399 



spotted internally. The aperture is rounded oval, with its sym- 

 metry disturbed above by the prominence of the posterior pli- 

 ciform pad ; it ends below in a short canal. Both lips are 

 white. The outer one is convex above, arcuated below, strength- 

 ened externally, armed at the edge with a few anterior sharpish 

 denticles, and guarded within by numerous raised spiral lines. 

 The inner lip is much incurved, and has only a few obscure 

 pimple-like elevations near the base. The callus or enamel is 

 not very broadly spread upon the body. Length nearly an inch ; 

 breadth fully half an inch. 



A not uncommon species, of ivhich ive have seen examples from 

 the Philippine Islands (Cuming), d'c. ; it was introduced into our 

 Fauna as dredged at Weymouth ! Montagu, whose description of 

 it is excellent, states that he had received it from Dr. Pulteney, in 

 whose Catalogue of the Shells, d'c. of Dorset it was first indicated 

 as British. Rackett, who copied the diagnosis in his second 

 edition of the same scarce work (p. 44) has figured a very different 

 shell {pi. 15, /. 13) ivhich looks more like a worn shell of the N. 

 reticulata, var. paucicostata {Kiener, Coq. Viv. Bucc. pi. 19,/. 7), 

 of ivhich we have seen an example, of questionable indigenousness, 

 once owned by Mrs. Loscombe.
