166 J. WILFRID JACKSON ON 



Full particulars, up to 1892, of the various recorded stations, will be found in 

 FISCHER and OEHLERT'S memoir on the Brachiopodes du Cap Horn (1892), where 

 also is given the most complete description of the species. 



One citation, however, calls for special remark. 



Like Terebratella dorsata, this species has also been recorded from Kerguelen. 



E. A. SMITH (1879) mentions Waldheimia dilatata, Lam. (a synonym of M. venosa, 

 Sol.), as having been obtained at Observatory Bay, Kerguelen, on rocks at 4 fathoms. 



DAVIDSON (R. B., p. 52), however, remarks that the Challenger did not bring back a 

 single specimen of SOLANDER'S species. 



Without an examination of the original specimens it is impossible to say whether 

 these are rightly referred to M. venosa, but I am disposed to doubt the correct 

 determination, in the light of recent research on the Brachiopoda of both regions. As 

 BLOCHMANN (1906) has shown, the specimens formerly recorded from Kerguelen as 

 Terebratella dorsata have proved to belong to a new species, viz. T. enzenspergeri, Bl. 

 It does not seem unlikely, therefore, that the Magellaniae in question may likewise 

 have been erroneously referred to the characteristic Magellanic species. 



With regard to the fossil distribution of this species, little appears to be known. 



PILSBRY (1898, p. 329), in a reference to a collection of Tertiary fossils from Cape 

 Fairweather, Patagonia, remarks that M. venosa (Sol.) is abundant. 



According to ORTMANN (1902), however, this identification is incorrect, the species 

 in question being named by this author Terebratella giyantea.
