Mr. T. Davidson on Recent Terebratulse. 35 



of but small importance, and easily corrected, and might have 

 occurred to any naturalist. The third point has reference to 

 Prof. Suess having followed me while quoting Corea as the ha- 

 bitat of Kraussia Deshayesii, instead of the Cape of Good Hope, 

 as given in the f Moll. Voy. Samarang :' but here, again, I was 

 misled by Mr. Cuming, just as Mr. Reeve was himself when 

 doubting his own original statement relative to the habitat of 

 T. abyssicola ; for he, as well as myself, had been misled by a 

 displacement of the labels in Mr. Cuming's collection. 



The fourth and last point has reference to the supposition 

 made by Prof. Suess that T. frontalis might perhaps be identical 

 with T. transversa, which is in all probability a mistake, but 

 a point to which Prof. Suess did not attach any importance, 

 and could not be blamed for having stated that T. frontalis was 

 " quasi the representant of T. spitzbergensis in the North Pacific," 

 recognizing at the same time that both were specifically distinct. 



Notwithstanding the high value of the monograph and revised 

 lists of recent Terebratulse recently published, the subject will 

 still demand further attention and study, on account of the 

 great difficulties connected with the classification of some of the 

 species ; it will therefore perhaps be as well for me to conclude 

 by reproducing the list of species as determined by Prof. Suess, 

 Mr. Reeve, and others, to which I will add some suggestions and 

 alterations which have appeared to me desirable. 



Family Terebratulidse. 



[An * is placed before those species of which I have not seen spe- 

 cimens, and a 1 before those whose generic or specific claims have not 

 been, to my mind, satisfactorily established. For all details and full 

 descriptions the reader is referred to Prof. Suess's ' Wohusitze ' and 

 to Mr. Reeve's 'Monograph ' and other papers.] 



Genus Terebratula, Lhwyd (restricted). 



1. Terebratula vitrea, Born, sp. Hab. Mediterranean. 



*2. Terebratula minor, Philippi and Suess. Hab. Mediterranean. 



I am not acquainted with this shell, which Prof. Suess assures 



me is distinct from T. vitrea, that it is smaller, with stronger 



valves and blunt margins, and that Philippi has pointed 



out the constant differences between the two, though he 



possessed only fossil specimens, while the Imperial Museum 



of Vienna has it both fossil and recent. T. euthyra, Philippi, 



as Prof. Suess has shown, is a Waldheimia with a long loop, 



as figured in pi. 1. fig. o of his German edition of my 



' General Introduction ;' and therefore Dr. Gray and Mr. 



Reeve were mistaken in supposing it a synonym of T. 



vitrea. W. euthyra is a fossil 'species, and not known in 



the recent condition. 



3. Terebratula uva, Brod. Hab. Falkland Islands.
