PRE-PENNSYLVANIAN (?) SPECIES. 
Fistulipora willisiana Girty.

Fistulipora willisiana Girty, 1907, Proc. U. S. Nat. Mus., vol. xXxxuil, p. 41. 
This species grows in thin epithecate expansions, occurring in considerable 
numbers in the limestone of which it appears to constitute a paleontologic feature 
of some importance. ‘The largest fragment seen measures 15 mm., but the original 
size may have been considerably greater. The thickness of the typical specimen 
is but little over 0.5 mm. ‘The growth is irregular and contorted. Macule are 
present, but their size and distribution have not been determined. The zocecia 
are quite small; they occur six or seven in a distance of 2 mm., and are situated 
at intervals of about one or two times their own diameter. A lunarium is well 
developed. Mesopores are usually large and as a rule separate the zocecia in single 
rows. ‘They are about the size of the zocecia themselves, and in some cases are 
even larger. 
This species is distinguished by its thin lamellate growth and by the small size 
of the zocecial tubes. 
Locality and Horizon.—Pre-Pennsylvanian (?); near T'a-miau-ssi, East Ssi- 
ch’uan (stations 6, 8, and 9). 
Fistulipora sp. 
Associated with the foregoing is another more massive species. The structure 
has, unfortunately, become so obscure in process of fossilization that it can not be 
studied by means of thin sections. One colony is 8 mm. thick, and, being fragmen- 
tary, measures I2 mm. across. 
Locality and Horizon.—Pre-Pennsylvanian (?); near Ta-miau-ssi, East Ssi- 
ch’uan (stations 6 and 9). 
Leioclema sp. 
This title is employed for a small, cylindrical, possibly branching bryozoan 
which occurs in some abundance at stations 6 and 8. The usual diameter is from 
2.5to3mm. In the course of fossilization the microscopic structure has been much 
obscured, so that an accurate determination of the genus is no longer possible. So 
far as can be made out, however, it seems to belong to Leioclema and to be related 
to the American species punctatum. 
Locality and Horizon.—Pre-Pennsylvanian (?); near Ta-miau-ssi, East Ssi- 
ch’uan (stations 6 and 8). 
Teniodictya ? sp. 
Of this species our collection affords a mere fragment, the length of which is 
about 10 mm. and the width, representing about the true dimensions, in the neigh- 
borhood of 2mm. ‘The growth indicated is a parallel-sided frond having a section 
of compressed elliptical shape. The cells are very small and slightly oval in outline, 
the long diameter being parallel to the axis. There are about ten longitudinal rows, 
which are arranged in alternation, so that the apertures are placed quincuncially. 
The distance between two apertures in diagonal or transverse rows is about the 
same, approximately equal to an apertural diameter, and it is considerably less than 
that between two apertures in the same row longitudinally. The interapertural 
spaces appear to be ornamented with many little raised points.
