 Professor Suess describes an unpublished Terebratdla received 

 from Dr. Gould with the habitat "Hakodadi" and name in 

 manuscript " T. miniataJ" Can it be our T. Coreanica ?

An examination of more than a dozen specimens of this 

 charming little species, most of them with the soft parts mace- 

 rated, so as to afford excellent comparisons of the loops, has 

 convinced me that Mr. Sowerby's T. pulchella is merely a variety 

 of his T. sanguinea {Anomia sanguinea, Chemnitz), in which the 

 deltidium plates are forced asunder by circumstances in its mode 

 of attachment. The apophysis is the same in both forms, 

 differing somewhat from tlie typical form of the apophysis in 

 Terebratella, and partaking of that in Megerlia.

T. Spitzbergensis is a small, narrowly-ovate species, smooth 

 and semipellucid like the large T. vitrea. Professor Suess 

 remarks that the figure of a species of Middendorf, which is 

 unknown to me [T. frontalis), is like it. Can they be one and 

 the same species? But Professor Suess goes on to ask, is T. 

 frontalis the same as T. transversal — which has no relation 

 whatever, as a comparison of our figures of that species in ' Conch. 

 Icon.' with T. Spitzbergensis will show. 



Subgenus 5. Magas, Sowerby. 



Apophysis a loop resembling that of Terebratella, but contracted, 

 and having the cross piece broadly laminated next the central 

 septum.
