36 Mr. T. Davidson on Recent Terebratulse. 



Subgenus Terebratulina, D'Orbigny. 



4. Terebratulina caput-serpentis, Linn., sp. Syn. Anomia pu- 

 bescens and A. retusa, Linn. = jT. nucleus, Midler = T. cos- 

 tata,Ijnm. = T. emarginata and quadrata, Risso. T. au- 

 rita, Fleming=7\ striata, Leach = 7\ septentrionalis, Cou- 

 thouy=7 1 . conica, WOrh. =Delthyris spatula, Menke. 

 Hab. This species has probably a more extended range than 

 is usually supposed, viz. the North and South European 

 and North American seas. 



?5. Terebratulina cancellata, Koch. Hab. West Australia. 



? 6. Terebratulina abyssicola, Adams & Reeve. Hab. Cape of 

 Good Hope. 

 It is probable that these two so-termed species should be 

 united, and it is also possible that they may be nothing 

 more than varieties of T. caput-serpentis. 



1 7. Terebratulina japonica, Sow. Hab. Corea, Japan. Mr. 

 Reeve justly observes that this species (?) is closely allied 

 to T. caput-serpentis. 



8. Terebratulina radiata, Reeve. Hab. Corea. 



9. Terebratulina Cumingii, Dav. Hab. China Seas. 



Dr. Gould describes and figures, in the 'United States Ex- 

 ploring Expedition, Mollusca,' under the name of T. pata- 

 ffonica, a shell which Prof. Suess believes to be perhaps a 

 new Terebratulina ; but to determine this point an exa- 

 mination of the specimen itself would be absolutely neces- 

 sary. Hab. Coast of Patagonia. 



Genus? Waldheimia, King. 



10. Waldheimia venosa, Solander, 1/89. Syn. T. globosa, Val. 



apud Lam. 181 9 = T. californica, Koch = T. Kochii, Kris- 

 ter = T. eximia, Philippi=7 T . physema, Val. apud Reeve. 

 Hab. Falkland Islands ; California ; Coquimbo. First 

 discovered about a century ago by Capt. Cook, this is the 

 largest known among the recent species, and has received 

 many names. It appears to me that the T. physema, 

 Val., is only a slightly different shape of T. venosa ; and 

 I am somewhat inclined to look upon T. dilatata also as 

 another modification. The term venosa has been known to 

 M. Deshayes and myself for several years. 

 ? 1 1 . Waldheimia dilatata, Val. apud Lam. Syn. T. Gaudichaudi, 

 Blainv. Hab. Same locality as the preceding species. 



12. Waldheimia lenticularis, Desh. 1839. Hab. New Zealand. 



The same species is found fossil in the neighbouring cliffs. 



13. Waldheimia picta, Chemnitz. Syn. T. erythroleuca, Quoy 



= T. sanguinea, Sow., not Chemn. Hab. Java. 



14. Waldheimia cranium, Muller. Syn. T. subvitrea, Leach = 



Macandrevia cranium, King. Hab. North European 

 seas. 



15. Waldheimia septigera, Loven. Hab. Norway; Finmark.
