PROBOSCINA CRANEI, new species 
Plate 152, figs. 8, 9. 
Description. — The zoarium incrusts shells in large, short, triserial clavifonn 
branches. The tubes are indistinct, large, short, arranged in quincunx or in trans- 
verse rows. The peristome is very thick, orbicular, somewhat oblique. The zooecia 
are generally adjacent, two by two, but they are sometimes isolated. 
We dedicate this vigorous species to our friend, Mr. W. E. Crane, who has col- 
lected many bryozoa for us both in Europe and America. 
I Maximum width of zoarium 1.00 mm. 
Measurements . — ] Length of tube 0.40 mm. 
Diameter of peristome 0.28 mm. 
Occun'ence. — Vicksburgian (Marianna limestone) : Salt Mountain, 5 miles 
south of Jackson, Alabama (very rare). 
Holotype. — Cat. No. 65377, U.S.N.M. 
PROBOSCINA IDMONEOIDES, new species. 
Plate 117, figs. 1-A. 
D escription.- — The zoarium incrusts shells in rectilinear, multiserial branches. 
The tubes are distinct, cylindrical, arranged in divergent rows on each side of the 
zoarial axis. The peristome is thin, salient, elliptical, with a distal extremity often 
pointed ; the peristomie is short, bent upward, oblique, directed toward the lateral 
margins of the zoarium. All the branches are not clearly idmoneiform, but the 
zooecia are always arranged in oblique rows. Evidently the peristomes are always 
free and wide spread. 
I Maximum width of zoarium 1.5 mm. 
Measurements . — j Length of tube 0.30-0.40 mm. 
| Diameter of peristome 0.14 mm. 
Occurrence. — Upper Jacksonian (Ocala limestone) : Old Factory about 14 
miles above Bainbridge, Georgia (rare) ; Bed Bluff on Flint Biver, 7 miles above 
Bainbridge, Georgia (rare). 
Cotypes . — Cat. No. 65293, U.S.N.M. 
PROBOSCINA MAGNIRAMOSA, new species. 
Plate 11', figs. 6, 7. 
Description. — The zoarium is multiserial and incrusts Cellepores in undulated 
targe branches. The tubes are little distinct, cylindrical, arranged in quincunx, 
rather regular and crowded. The peristome is orbicular, very oblique, thin; the 
peristomie is long and oblique. 
Maximum width of zoarium 2.00 mm. 
, Length of tube 0.30-0.40 mm. 
Diameter ot peristome 0.16 mm. 
Length of peristomie 0.32 mm.
