TURRIT ELLA. 19T 



T. terebra of Linn. Faun. Suec, but not of the Systeraa, and 

 some conchologists prefer this name ; it is more frequently known, 

 however, as T. cornea, Lam., although its identification is not 

 be^'ond question. Other synonyms are T. ungiclina, Loven, etc. 

 (not Linn.),2'. Linnsei^ Deshayes, and T. imbricosoluta, Gregorio, 

 the latter described as a variety. 



T. Capensis, Krauss. PI. 60, fig. 47. 



Whorls about 15, rounded, brownish, white-clouded, with 

 irregular obtuse revolving lines and deep suture, base a little 

 angulated, aperture light brownish. Length, 28 mill.

Yery slender ; whorls about 18, convex, four-ridged, suture 

 deeply impressed ; yellowish, chestnut banded at the suture.

Menke described his species without locality; the shell which 

 Reeve has figured for it is said, on the authority of Cuming, to 

 have been dredged in " Bay of Montija, Central America (in 

 coarse sand at the depth of seven fathoms)." That this habitat 

 is an error can scarcely be doubted ; not only has the locality 

 failed to yield additional specimens, but Mr. A. Adams has 

 recognized in the figure a Japanese species of which the unfigured 

 7'. gracillima, Gould, of Japan, likewise, is a synonym. My 

 type specimens of the latter confirm this. T. bicolor, A(}. and 

 Reeve (fig. 37), is another S3'nonym.
