DAPHNELLA. 309 
Michaud, D. gracilis, Scacchi, D. Payraudeauti, Weinkauff (not 
Deshayes), and perhaps D. Bivone and D. Valenciennesit, 
Maravigna, and D. vulpina, Bivona, are also referred to this 
species. 
D. costuLaTA, Blainv. PI. 21, figs. 19, 23. 
Narrowly but distinctly shouldered, ribs 9-10, crossed by fine 
revolving lines, which are almost microscopic; buff or pale 
yellow, sometimes with a chestnut band on the periphery, or 
below the suture, or with several narrower bands. 
Length, 12-15 mill. 
Europe, Madeira. 
The synonyms are D. striolata, Scacchi (fig. 19), D. Leviana, 
Forbes (fig. 23), D. Smithii, Forbes, D. elegans, Brown, D. Far- 
ranivi, Thompson, and possibly D. fenestrata, Desh., D. Steveni, 
Krynicki, and D. costulata, Cantraine. The latter was supposed 
identical with Columbella Halixeti, Jeffreys (Manual, v, 160, t. 
56, f. 77), with which opinion that author himself agreed, until 
recently (Zool. Proc., 392, 1883)—when he refers it to the present 
species. 
D. semicoton, S. Wood. PI. 4, fig. 56. 
Strongly shouldered, forming a carinated and tuberculated 
periphery, with well-marked sculpture. Length, 10 mill. 
Mediterranean, Shetland Islands, North Sea. 
Reported in a recent state by Dr. Jeffreys, from the above 
localities, under the name of D. galerita, Phil. (figured), but that 
Species, a Sicilian fossil, appears to differ. The figure given by 
Jeffreys corresponds with that of D. semicolon, in Wood’s Crag 
Mollusca sufliciently to justify Monterosato in uniting the two 
species. 
D. mrnutA, Forbes. PI. 21, fig. 16. 
Shell strongly ribbed, distantly spirally striate; reddish brown. 
Length, 5 mill. 
Aigean Sea. 
Perhaps a variety of D. turgida, Forbes. 
D. asyssicona, Forbes. PI. 21, fig. 15. 
Ribs strong, crossed by rather distant raised striz ; chocolate- 
brown. Length, 4 mill. 
Aigean Sea.
