MIOCENE MOLLUSCA AND CRUSTACEA. 131 
Judging from the condition of the remains of this species I think it 
may have been a rather thin and fragile shell, as the specimens are flattened 
and crushed almost out of shape. The volutions have been highly convex 
and rather short, somewhat more so than would be indicated by Mr. 
Say’s figure above cited, while the strize would seem to have had flattened 
interspaces, the strize themselves being distinctly raised lines of nearly equal 
width with the interspaces. I should suppose from the specimens seen that 
it would properly belong to the genus Mesalia Gray. 
Formation and locality: In a dark micaceous clay marl of the Miocene 
from the well-boring of Mr. L. Woolman, at Atlantic City, N. J. From the 
collection of the Academy of Natural Sciences at Philadelphia. 
Family VERMETID2. 
Genus ANGUINELLA Conrad. 
Miocene Fossils, pp. 77 and 78. 
It does not appear that any aescription of this genus was ever pub- 
lished by Mr. Conrad. The nearest approach to one is the simple compar- 
ison with Serpula and Petaloconchus of Lea, made on p. 78 of the Miocene 
Fossils, which is as follows: “This genus differs from Serpula in having 
septa, and from Petaloconchus Lea in wanting the revolving plates.” The 
bodies to which he applied the name are contortedly coiled tubes, closely 
resembling those of Serpula, or are like those of Vermetus, except that they 
do not form regular volutions during the earlier stages of their growth, as 
do those shells. They appear to have been adherent to foreign bodies, and 
to have formed straight tubes, or to have had a laterally spiral form for a 
time, after which they grew in an irregularly coilig manner. The distin- 
euishing feature, however, is that of having the tube divided into chambers 
as it advanced in length, by deeply concave or ‘vaulted septa” at irreg- 
ular distances. The first impression one receives of the shell is that it 
belonged to an annelid, and not to a true mollusk. This would appear
