creeping, often united into an irregular membrane ; fertile erect, 

 generally slightly branched, but sometimes subdichotomous ; 

 pycnidia serai-ovate ; pcrithecia curved, acuminate. 



It is difficult to say what is a species in this genus, which will 

 ultiaiately coalesce with Capnodium, of which it appears to present 

 one form of fruit. A few curved acuminate perithecia without 

 fruit were scattered amongst the threads.

XLIV. — A Reply to Prof. Sedgwick's Article published in the 

 Annals and Magazine of Natural History, 2nd Series, No. 76, 

 April 1854. By Prof. Milne-Edwards. 



To the Editors of the Annals of Natural History. 



Gentlemen, 



Professor Sedgwick having inserted in the Number of your 

 Journal that I have just received (April 1854), an extensive 

 article on certain passages in the 'Monograph of the British 

 Fossil Corals ' published two years ago by M.J. Haime and 

 myself, I hope you will allow me to lay my reply before your 

 readers. 



Two points are discussed in Prof. Sedgwick's article : the first 

 is relative to the refusal of the loan of fossil corals belonging to 

 the Cambridge Museum ; the second to what we considered as 

 being our scientific property, and had seen presented to the 

 public in Prof. McCoy's last work, without any reference to its 

 origin. 



' § 1. When some of the Members of the Council of the Palseon- 

 tographical Society proposed to me the laborious task of de- 

 scribing the Fossil Corals of England, Mr. Bowerbank, Sir H. 

 de la Beche, Mr. Davidson, and some more of my friends, kindly 

 undertook to obtain for me the loan of the necessary specimens. 

 The efforts of those gentlemen were so successful, that I soon 

 received in Paris ample materials for most parts of the intended 

 work : the Corals belonging to the Geological Society, the Mu- 

 seum of Bristol, the collections of Mr. Bowerbank, Mr. Stokes, 

 Sir H. De la Beche, Mr. Searles Wood, Mr. Fred. Edwards, 

 Mr. Wetherell, Mr. Pratt, Mr. D. Sharpe, Mr. Walton, Dr. 

 Wright, Dr. Battersby, Mr. Pengclly, Mr. Fletcher, Mr. J. 

 Gray, Prof. Phillips, and several other geologists, were in the 

 most liberal manner placed at my disposal for publication, and 

 I eagerly seize this opportunity to renew my thanks for the 

 aid so afforded to my researches. In order to complete some
