NEW TUBULIPOROID BRY0Z0A—BA88LER. 



521 



This species is represented in the collections of the U. S. National 

 Museum by two excellent specimens from the type-locality, and 

 by a third form from Minnesota, all of which agree with the descrip- 

 tion and measurements given above. The exceptionally large 

 swelling of the zocecia, and the very short and narrow stolonal por- 

 tion are in such contrast that little difficulty should be experienced 

 in recognizing the species. The amount of divergence of the zooe- 

 cium proper is about 50°. A similar abrupt swelling of the same 

 region is present in C. curta and C. abrupta from the Richmond 

 group, but each of these has zooecia only one-third the size of those 

 of C. turgida. 



Occurrence. — Rare in the Richmond group (Fernvale shale) at 

 Wilmington, Illinois, and in the same group at a locality 3 miles north 

 of Spring Valley, Minnesota.

CORYNOTRYPA DEVONICA (Oehlert). 



Eippothoa devonica Oehlert, Bull. Soc. d'Etudes Scientifiques d'Angers, vol. 17, 

 1888, p. 104, pi. 10, figs. 2-2f. 



This species is known to me only from Oehlert's illustrations^ 

 which are here reproduced. Judg- 

 ing from these figures and from 

 the magnifications ascribed to 

 them, C. devonica belongs to the 

 C. injlata section of Corynotrypa, 

 but differs in its conspicuously 

 smaller size. C. injlata has eight ' 



a 



or more zooecia m 5 mm.

fourteen to fifteen occur in the 

 same diameter in C. devonica. It 

 is probable that more careful study 

 and illustrations of Oehlert's spe- 

 cies will reveal other differences, 

 although present knowledge is suffi- 

 cient to place the form generically 

 and to point out its specific rela- 

 tionships. 



Occurrence. — Devonian, La Baconniere, Department de la Mayenne, 

 France.
