10. Terebratula {Waldheimia) physema, Valenciennes, MS. in 

 Mus. Jardin des Plantes ; Conch. Icon. pi. 6. f. 23 a, b, c. 

 Hab. Coquimbo ; Gaudichaud. 



This fine shell, belonging to the Museum of the Jardin des 

 Plantes, had been regarded as a variety of T. {Waldheimia) 

 dilatata ; but when M. Valenciennes was making a selection of 

 the specimens of Terebratula to send me, it appeared to him to 

 be distinct, and he made the following note on the back of the 

 tablet : — " Grande et belle espece de Terebratule ( Waldheimia) 

 confondue avec mon T. dilatata, vsLpTporiee de Coquimbo en 1833 

 par M. Gaudichaud, et donnee par lui h. M. Ferussac. Achetee 

 en 1837 avec la collection." It is intermediate in its characters 

 between W. globosa and W. dilatata, inclining rather to the 

 former species, of which it may possibly be only a colossal, 

 broadly inflated variety.

 and pi. 6. f. 2 b, c. 



Terebratula Gaudichaudi, De Blainville. 



Hab. Coquimbo ? Strait of Magellan ? 



This species I have also had the pleasure of verifying from the 

 original type, formerly belonging to M. Dufresne, and now in 

 the Paris Museum. The habitats rest in doubt. Coquimbo 

 seems the most likely to be correct; but I have just been fa 

 voured with a visit from a gentleman recently arrived from the 

 first-named habitat, who assures me that he collected some 

 mutilated remains of a large shell, like W. dilatata, at the Falk- 

 land Islands. Unfortunately he threw them away.

Hab. New Zealand (dredged in the Strait of Faveau at the 

 depth of 15 fathoms) ; Deshayes. 



Except in colour, this species is scarcely distinguishable from 

 T. {Waldheimia) globosa.
