132 PALEONTOLOGY OF NEW JEIiSEY. 



to have been the general opinion of authors, as it is seldom found in cata- 

 logues of Mollusca. The genus might be characterized as follows: 



Shell tubular, irregularly coiled like Vermetus Adamson, but sinis- 

 trally, adherent in its earlier stages; smooth or variously ornamented exter- 

 nally; internally divided at irregular intervals by transverse partitions. 



The substance of the shell is readily divided into two distinct layers, 

 but I fail to find a third, as is usual in the Vermetidae ; the shell is lamellar 

 and not vesiculose. In a single small specimen attached to a larger tube, 

 the spiral nucleus is distinctly seen; so I am inclined to think it a mollusk 

 and not an annelid. 



In regard to the validity of the genus I am not satisfied. It would 

 appear to rest principally upon the septate character of the tube, but as this 

 is not unfrequent among the Vermetidae, it would appear to be of doubtful 

 value, and I must leave others to judge for themselves as to its right to a 

 place, since the name has long ago entered into the literature of the Mol- 

 lusca.

" Terete, slender, adhering, with strong annular wrinkles; toward the 

 apex are contiguous volutions, somewhat angular or subcarinated; the 

 whorls with obsolete revolving lines and subcarinated near the base; inter- 

 nally furnished with vaulted septa." 



The specimens of this form which I have received are all of small size, 

 and represent only the apical portions of the shell. The earlier volutions 

 are more regularly coiled than below, but never appear to form regular 

 volutions, as do most species of Vermetus, being laterally divergent. The 

 surface of the shell is marked with fine longitudinal, but irregular and often 

 broken striae, which on the lower, or adherent side of the tube, are spiny or 

 strongly granulose, but more regular on the upper side; also by very irreg-
