BRACHIOPODA. 233 



St. John shells are preserved as external and internal casts, and from some of 

 these there is reason to infer that the substance of the shell was punctate. 

 Mr. Matthew, in a private note, intimates that his Kutorgina Latourensisf may 

 belong to the same group of shells. This species has been discussed in the 

 preceding pages, under the genus Kutorgina,^ and although an examination of 

 the more complete material received from Mr. Matthew, w"ith his identifica- 

 tion, has not proved entirely conclusive, there are reasons in favor of adopting 

 the views of this author.
