PROBOSCINA CRANEI, new species 



Plate 152, figs. 8, 9. 



Description. The zoarium incrusts shells in large, short, triserial claviform 

 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. 



Maximum width of zoarium- - - 1.00 mm. 



Length of tube 0.40 mm. 



Diameter of peristome 0.28. mm. 



Occurrence. Vicksburgian (Marianna limestone) : Salt Mountain, 5 miles 

 south of Jackson, Alabama (very rare).

PROBOSCINA IDMONEOIDES, new species. 



Plate 117, figs. l-A. 



Description.^^ 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. Length of tube 0.30-0.40 mm.

Occurrence. Upper Jacksonian (Ocala limestone) : Old Factory about H 

 miles above Bainbridge, Georgia (rare) ; Eed Bluff on Flint River, 7 miles above 

 Bainbridge, Georgia (rare).

PROBOSCINA MAGNIKAMOSA, new species. 



Plate 11', figs. 6, 7. 



Description. The zoarium is multiserial and incrusts Cellepores in undulated 

 large brandies. 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.
