Lorraine Faunas of New York and Quebec 315 
found. The tubes are crossed by annulations, which are rather 
angular on the crest, sloping with about equal rapidity into the 
concave constrictions both above and below each annulation. 
Tube very thin, the interior cast also annulated; annulations 
sloping gradually in the distal direction, and abruptly on the 
proximal side; in fact, on the proximal side these annulations 
often are slightly incurved. Exterior with very fine and numer- 
ous longitudinal striations, often alternating slightly in size. 
At each annulation these longitudinal striae begin as very fine 
striae on the distal side of the crest, dip into the constricted parts, 
and become stronger on rising up the proximal slope of the next 
annulation. Of these longitudinal striae there are about 8 or 9 
in a width of 1 mm. around the circumference, with an equal 
number of still finer, intermediate ones, visible under a lens in 
specimens preserved in fine grained strata. Transverse striations 
are present in some specimens, but can be seen only with a magni- 
fier and under strong cross illumination. The length of the speci- 
mens at hand scarcely exceeds 15 mm. This is the species figured 
by Hall on plate 78 of the Paleontology of New York, in vol. I. 
Two miles west of Worthville, on the road to Lorraine, another 
form occurs associated with Trinucleus and other fossils suggesting 
a fauna very similar to that east of Pulaski. In this form of 
Cornulites the annulations also are rather sharp along the crest, 
but they tend to slope more rapidly on the distal than on the 
proximal side. Their chief characteristic, however, is the coarse- 
ness of the longitudinal striae, which become so strong on ascend- 
ing the proximal slopes that they give an almost nodular or 
scalloped appearance to the crest of the annulations. Of these 
nodules there are about 5 in a width of 1 mm. around the circum- 
ference. Under strong cross illumination very fine intermediate 
longitudinal striae can be seen, a single node sometimes represent- 
ing the distal termination of two or even three striae. Transverse 
striae are readily distinguished under a lens in some specimens. 
Although the two forms here described present quite a different 
general appearance, the second may be only a more vigorous form 
of the first, and a much more extended study is necessary to 
determine their degree of relationship. 
In referring these tubes to Cornulites, the writer has merely 
followed Hall.^ Cornulites flexuosa, Hall, was founded on a form
