Geographical Distribution of the Terebratulse. 173 



preceding, but it appears distinct. Great doubt, I think, at- 

 taches to the habitat, " West Australia, " given by M. Koch. 



6. Terebratula {Terebratulina) ahyssicola, Adams and Reeve, 

 Moll. Voy. Samarang, p. 72, pi. 21. f. 5 ; Conch. Icon. pi. 4. 

 f. 14. 



Hub. Corea; Belcher. 



]\lr. Davidson has truly remarked that this and the preceding 

 species require further examination; but no other specimens 

 have been collected since he wrote. One important error needs 

 to be corrected. In the original description of T. abyssicola 

 in * Moll. Voy. Samarang,' the habitat of Kraussia Deshayesii 

 was accidentally repeated. Mr. Cuming possesses the shell 

 correctly labelled " Corea." 



7. Terebratula [Terebratulina) radiata, Reeve, Conch. Icon. pi. 3. 

 f. 7a,b. 



Hab. Strait of Corea ? 



Of this black-rayed species, which appears to me to be a very 

 distinct one, Mr. Cuming possesses three exactly similar speci- 

 mens, procured, he fancies, from the dredgings of Capt. Sir E. 

 Belcher in the Strait of Corea. 



8. Terebratula [Terebratulina) Cumingii, Davidson, Proc. Zool. 

 Soc. 1852, p. 79, pi. 14. f. 17-19 ; Conch. Icon. pi. 4. f. 12. 

 Hab. China Seas. 



A small, well-defined species, rather prominently bifurcately 

 ridged. 



Subgenus 3. Waldheimia, King. 



Apophysis a free, largely-produced, riband-like loop, considerably 

 reflected. 



9. Terebratula ( Waldheimia) ^foiosa, Valenciennes apud Lamarck, 

 Anim. sans Vert. vii. p. 330 ; Conch. Icon. pi. 2. f. 3 a, b, c, 

 and pi. 6. f. 3 d, e. 



Terebratula Californica, Koch. 



Hab. California, Coquimbo. 



When publishing this species four months since, in pi. 2 of 

 my monograph in * Conch. Iconica,' I ventured to assign to it the 

 shell well known in collections as T. Californica, Koch. On 

 receiving subsequently from M. Valenciennes the original type 

 of his T. globosa, very clumsily figured in the * Encyclopedic 

 Methodique ' (which figure is copied, with all its infirmities, on 

 a reduced scale in De Blainville's ' Malacologie '), I found the 

 opinion that I had formed to be the correct one.
