Ai\ derived from figure 44 of Walker's " Testacea Minuta." j\Ir. Jeffreys 

 thinks this may probably be a form of 7?. labiosa. 



The following Rissoa are figured in Brown's " Illustrations of the Recent 

 Conchology of Great Britain and Ireland ;" but, from the imperfection of the 

 magnified representations of the more minute species in that work, we have not 

 been able to recognize them. 



/?. Binghami, p, 10, pi. 9, f. 29. — Has the general aspect of R. jMontagui, of 

 Payraudeau. Of the known British Shells, R. iiico7ispicua, perhaps, comes 

 nearest to its description. 



R. obtusa, p. 10, pi. 9, f. 27, 28. — Has the general aspect of R. Zetlandiva. 



R. laciea, p. 11, pi. 9, f. 77. — Allied to R. Bryerea. Exotic? 



R. sulcata, p. 10, pi. 9, f. 69. 



R. Candida, p. 1 1, pi. 9, f. 75. — Somewhat allied to R. Bryerea. Exotic ? 



R. turricida, p. 10, pi. 9, f. 18. — Not like any of our known shells. Exotic ? 



R. vitlaia, p. 15, pi. 8, f. 29. — Slightly resembles the \av.fasciata oi R. parra.

 Cingula Brugieri, Brit. Marine Conch, p. xli. fig. 38. 



A Mediterranean shell ; introduced, in the British Marine Con- 

 chology, as 2)^'obahly taken at Scarborough. The specimen was 

 forivarded as British by Mr. Bean, who, it aj^pears, had received it 

 as from the Channel Islands, and sent it as the t7Xiditio7ial Turbo 

 coniferus of Montagu. Its identity with that shell is likewise 

 asserted by Professor Forbes, in his account of the Egean Inver- 

 tebrata.
