was trying to provide a new Ordinal name, but they cannot be 

 referred to Conularidd for any reason that he suggested or for 

 any other reason thus far put forth. We use the word Conularida 

 for pelagic shells having lime-phosphate and not in the sense in 

 which Waageu used it. It is the natural and proper Ordinal 

 name to include the family C'o«M/arn'r/<r and cannot be preoccupied 

 for any other purpose, besides, it has been used by others without 

 defining it, for substantially the same purpose that we now use it. 

 The family Conidariiihr does not belong to any living order of 

 animals, and hence the necessity for providing an Ordinal name 

 to receive it. And the same may be said of Enchosl<>»ii(l(c.

There have been described, from the Palasozoic rocks of North 

 America fifty-nine species of i'onularia, besides three that have 

 been named, but too poorly defined to be recognized. Among tlie 

 fifty-nine species is C. yatiingeri, which was named by Satl'ord, in 

 the Geology of Tennessee, p. 280, and compared with C. trenioii- 

 ensis, by saying, that it is larger and about ten inches long, and 

 that it was found by Dr. Gattinger, while digging a cellar for his 

 house, in the trenton limestone, in Nashville, Tennessee. This 

 definition is exceedingly imperfect, but Dr. Gattinger made num- 

 erous plaster casts of the specimen and distributed tiiem among 

 the scientific men of the country (one of which was presented to 

 S. A. Miller, by Dr. Gattinger, about twenty years ago), which 

 made the form very generally known, and the remarkable size, if 

 other specimens have been found, has prevented any synonym 

 from being made. The species has been recognized, in all cata- 

 logues, and Dr. Gattinger has kindly loaned the original specimen, 

 to S. A. Miller, for examination and description, and we pro- 

 pose to describe it, in order tiiat the form may be better known 

 and the specific name retained. We have an invariable rule to 

 never name a new species without describing and illustrating it; 

 but this is not our species, and as a single figure will cover half 

 a plate, we will content ourselves by writing a description of the 

 specimen. 



The shell rapidly expands, is subtjuadrate in transverse section, 

 but the diameter is greater in one direction than in the other. 

 The sides are concave, in the superior part, which may or may 

 not be the normal condition, because the shell is flexible in this 

 genua. The four angles are deeply furrowed. There is a longi- 

 tudinal line, in the middle of each side. The shell consists of an
