368 Mr. T. Davidson on the Classification 



is the Ter. sanguinea, Leach (not Chemnitz), Ter. rubra, Sow., 

 by mistake Th. Conch, pi. 68. fig. 9-11, not T. rubra, Pallas. 



25. Terebratella crenulata, Sow. sp., 1846, Th. Conch, pi. 71. 

 fig. 96-98. 



Hob. Santa Cruz and Korea. In this species the loop is 

 doubly attached as in all Terebratella, but the central septum 

 forms an elevated plait almost reaching the larger valve; the 

 form of the loop is similar to that of T. Evansii, but slightly 

 different in its details. 



26. Terebratella Evansii, Dav. ; Zool. Proc, 1852. 

 Hab. New Zealand. 



27. Terebratella Labrador ensis, Sow. sp., Th. Conch, pi. 71. 

 fig. 89, 90. 



Hab. Labrador (Goodsir). 



28. Terebratella Algoensis, Sow. sp., Th. Conch, pi. 71. fig. 91,92. 



Hab. Algoa Bay. Only the larger or perforated valve is known, 

 but by analogy I suppose it to be a Terebratella. 



29. Terebratella transversa, Sow. sp., 1846, Th. Conch, pi. 72. 

 fig. 114, 115. 



Hab. Unknown. 



30. Terebratella rubella, Sow. sp., 1846, Th. Conch, pi. 69. 

 fig. 40, 42. 



Hab. Java. Mr. Sowerby states the loop to be simply attached 

 as in australis ; this however appears to me to be a mistake, as 

 Mr. Cuming has specimens showing traces of the double attach- 

 ment. 



31. Terebratella? sanguinea, Chemnitz sp., 1785; Sow. Th. 

 Conch, pi. 71. fig. 71, 73. 



Hab. Island of Zebu. This species appears to have the loop 

 attached somewhat as in Megerlia. 



32. Terebratella Cumingii, Dav. ; Zool. Proc. 1852. 

 * 



Hab. New Zealand. I am quite at a loss what to do with this 



form, which possesses many of the characters of Magas, Bouchar- 

 dia and Terebratella ; for the present I therefore leave it under 

 the latter genus, from whence it may be removed if future 

 discoveries render this necessary.
