NOTES ON THE BRITISH JURASSIC BRACHIOPODA. 239 



calminated in his posthumous " Monograph of the Recent 

 Brachiopoda" (11). 



In a footnote on page 40 of this valuable Avork reference 

 is made to the fact that Professor J. Hall, of America, 

 and Eug. Deslongchamps, of France, question whether the 

 term Waldheimia could be retained, as the name had been 

 given bj Brulle, in 1846, to a genus of hymenopterous 

 insects. 



So far as I am aware this is the first intimation by David- 

 son to the effect that any alteration of the name Waldheimia 

 would be necessary, which is strange, because Bayle, six 

 years previously, had proposed the name Magellania for the 

 shells under consideration. 



This term, Magellania^ is now generally in use among 

 those who study the brachiopoda, and as Miss Agnes Ci ane 

 says : " The substitute possesses the unusual merits of com- 

 memorating the exploits of a celebrated navigator, and of 

 indicating at the same time the region of the maximum 

 development of the genus it distinguishes ; for the Magel- 

 lanian province, as Darwin first pointed out, is remarkable 

 for the great size of the mollusca inhabiting it, and to this 

 rule the Brachiopoda form no exception " {Natural Science^ 

 Vol. II., No. 11, January, 1893). 



During the time Davidson was engaged in the compilation 

 of his Monograph, a period extending over thirty- four 

 years, Quenstedt, Douville, Deslongchamps, Bayle, Zittel, 

 and many other distinguished palaeontologists were at work 

 in their respective countries in elucidating the life-history 

 of the Brachiopoda, but it is unnecessary to review their 

 work in detail. However, a few words may be said con- 

 cerning the classification of the Terebratulidfe as proposed 

 by Eug. Deslongchamps in 1884 (12, p. 292). 



This author altogether ignored the greater or less length
