﻿256 SMITHSONIAN MISCELLANEOUS COLLECTIONS [VOL. 47 



Barrande in Waag'en states the following : 



" The family of Lobolithes is known only by the publication of 

 Prof. J. Hall under the name of Caniarocrinus. 



" Indeed for more than forty years we have shown visiting" savants 

 these remarkable specimens in our collection, which, however, we do 

 not suppose have made a deep impression on their minds. We an- 

 nounced these under the new name, Lobolithes, but have not called 

 attention to them by a proper publication. The time has been 

 lacking. 



" We now show the very diverse forms of this family on 13 plates 

 numbered 67 to 79 [not yet published]. 



" At this time we will not make comparisons between Lobolithes 

 and related families as the Cystidea and Crinoidea. A cursory ex- 

 amination of the 13 plates by an intelligent student will at once show 

 him that our new echinoderms are distinguished by the absence of all 

 regularity in their structure." 



Zittel's description, as translated by Eastman, is as follows : 



" Family 3. Camarocystidae. Barrande. 



" Calyx globose or discoid, composed of numerous polygonal plates, 

 and sometimes fixed by the ventral surface [this seems to refer only 

 to Lichcnocrinus as will be seen later] . Interior of calyx divided 

 into four to six compartments by partitions corresponding in posi- 

 tion to lobes on the exterior. Stem long and slender. Silurian. 



" This family embraces two genera whose systematic position is 

 still doubtful. The larger, Caniarocrinus, Hall (= Lobolithes, Bar- 

 rande), occurs in the middle and upper members of the Silurian in 

 North America and Bohemia, and attains considerable size. The 

 smaller, Lichenocrinus, Hall, is more or less crateriform, has a very 

 long, tapering stem, and is invariably attached by its flattened ventral 

 surface. It is found in the Ordovician (Hudson River Group) of 

 North America." 



It should be stated that Lichcnocrinus has no direct relationship 

 with Caniarocrinus, as it is a sessile body with a long column; the 

 base is composed of an upper series of small porous plates beneath 

 which is a very thin chamber with the basal layer finely striate 

 radially. There are no camarje like those in Caniarocrinus. The 

 latter, on the other hand, is a free body, and is never sessile nor 

 cemented to foreign objects as is Lichenocrinus. 



Haeckel's remarks, translated, are as follows: 



" In the Silurian System of Bohemia Barrande discovered quite 

 50 years ago the remains of large Echinoderma to which, in the 

 ' Programme Generale ' of his large work on Cystidea, he has applied 

 the name Lobolithus (Syst. Sil. du Centre de la Boheme, vn, 1887,
