446 Mr. L. Reeve on the Recent Terebratulse. 



that locality), that a mistake had really been made by Mr. Adams 

 and myself in repeating the same habitat and bathymetrical par- 

 ticulars for this species as are given in the preceding paragraph 

 for K. Deshayesii. The two habitats originally published have 

 been just proved to be correct by a most singular coincidence. 

 Mr. Davidson, while looking over his stores of recent Terebratulee 

 a few days since, discovered a group of Kraussia rubra (an un- 

 doubted Cape species) with three specimens of true Terehratulina 

 abyssicola attached to it, — dredged, beyond all question, like the 

 original specimens, together. 



4. The point of my criticism under this head is, that I object 

 to any sort of comparison between T. spitzbergensis and frontalis 

 and T. transversa. T. spitzbergensis^ as its name implies, is a 

 small, semitranspareut, subarctic form of Terebratula. T. fron- 

 talis, which is unknown to me (and I cannot gather much from 

 Middendorf 's figure in ' Reise Sib.^), is also a northern form of 

 Terebratula, the " quasi representative," as I have no reason for 

 doubting, of T, spitzbergensis in the North Pacific. But what 

 relationship can there be between either of these species and T. 

 transversa ? Prof. Suess has not seen T. transversa. The shell 

 in the collection of Mr. Norris which bears that name appears 

 to me to be nothing more than a huge worn monstrosity of the 

 bold T. magellanica, which ranges along the western coast of 

 South America from the Straits of Magellan to Chili. There is 

 no vestige of a loop in the shell, but its general resemblance to 

 Terebratella magellanica leaves no room for doubt as to the 

 genus to which it belongs. 



I am indebted to Prof. Suess for pointing out some errors in 

 my ' Revision -/ but they are unimportant, and little affect the 

 question of geographical distribution. I give Japan, instead of 

 Java, as the habitat of T. rubella, on the authority of a memo- 

 randum in the collection of Mr. T.Lombe Taylor, which I believe 

 to be correct. His specimens were procured from Capt. Sir E. 

 Belcher, who, according to this memorandum, dredged them in 

 that locality. My insertion of T. labradorensis (only known 

 from Labrador) among the North European instead of the 

 North American types is an unlucky blunder. The only error 

 which I admit in the whole list of my synonymy is that of 

 citing Waldheimia euthyra as a synonym of Terebratula vitrea. 

 The species is unknown to me ; and I followed Dr. Gray, in the 

 Museum Catalogue, not having seen the German edition of Mr. 

 Davidson's ' Classification of Brachiopoda,' in which the loop is 

 figured. 



Prof. Suess says, " Nor do I approve the altered generic posi- 

 tion of several species. Every one familiar with the fossil type 

 of the genus Magas must see that the generic position assigned
