being the largest specimeiTi of the genus yet found in the state. The 
surface is rendered irregular by large mastoid-like projections and by 
elevated maculae which are not very different from monticules. Macu- 
lae 5mm. apart, with fair elevation, surrounded by apertures slightly 
larger than the average. Zooecia average 0.28 mm. in diameter being 
nuich smaller than in typical specimens of the species ; the lunarium is 
more promi.ient. Tabulae a little farther apart ; the interstitial ves- 
icles vary more in size. This is a well marked variety and could be 
described as a new species. It may be a coral. Type in the museum of 
the University of Nebraska, Lincoln, Nebraska. 
Position and locality : Coal Measures ; Louisville, Nebraska.

The following description was furnished the writer by Mr. E. O. 
Ulrich, the author of the species. "Zoarium ramose dividing at rather 
long intervals ; branches sub-cylindrical, commonly from 7 to 12 mm- 
in diameter, but reaching 20 mm. in Texas specimens referred to the 
species. Maculae rather small, 5 or 6 mm. apart; zooecial apertures 
subcircular, nearly direct, separated by interspaces averaging a little 
less in width than their diameters, arranged in moderately regular 
rows, nine or ten in 5 nun. ; peristomes ring-like carrying, on the 
side opposite the lunarium, which is distinguished only by its slightly 
greater elevation and comparative smoothness, seven to ten small per- 
forated pustules. Similar pustules are scattered among the much 
smaller granules covering the depressed interspaces. Here and there, 
especially in the maculae, a small pore of uncertain functions may be 
observed. Liternal structure as shown in the' accompanying illus- 
trations. Named in honor of Mr. Manly D. Barber, of DeKalb, Illi- 
nois, from whom the first specimens seen of this well marked and 
widely distributed species were received. 
The generic position of C. barberi is uncertain, and we may add, 
so is that of a large proportion of the Fistuliporidae. The family 
requires thorough revision, and until that is attempted it would be, 
to saj'' the least, unwise to create generic groups." 
This is the first published description of the species, though its 
specimens are common in the collection of E. O. Ulrich, who not only 
gave the name, but has placed specimens in the National Museum 
under the above name- 
The species is quite readily distinguished from associated Fistuli- 
porae (to which genus it may belong) by its ramose form of growth, 
tigs. 3-8 were drawn by E. O. Ulrich.
