over to the late Dr. E. Schellwien at the University of Konigsberg, 

 who was generally considered as the leading authority in the world 

 upon the Paleozoic Foraminifera. After examining the specimen 

 he wrote me a letter which has been translated as follows by Berthold 

 A. Eisenlohr, associate professor of the Germanic languages and 

 literatures in the Ohio State University:

My dear COLLEAGtJE: 



I have examined the Fusulinas, which -you were so kind as to send me for 

 investigation, after making thin sections of them. They are genuine Fusulinas 

 of the Fus. regularis Schellw. type, a form which is rather widely distributed in 

 America and also occurs in lower horizons as the Cottonwood limestone. I beg 

 to remark that I have at my command a rather large amount of material in North 

 American Fusulinas, most of which comes from the National Museum. Ftisul. 

 cylindrica does not occur at all in America. I hope to be able to finish my work 

 on the Fusulinas next winter and will then send it to you. I regret that I have not 

 enough separates of my earlier papers in this subject 



With my kindest regards, 



_ Yours very truly, 



{Signed) E. Schellwien 



Since the above letter was written H. Yabe, of the Imperial Univer- 

 sity of Tokyo, has published "A Contribution to the Genus Fusulina" 

 in which occurs the following statement concerning specimens of 

 Triticites secalicus Say sent him by Dr. Girty : 



As I examined their sections under the microscope, I was fully convinced of 

 the correctness of his remarks on the peculiar structure of the form; yet I am still 

 in doubt whether it is possible to separate satisfactorily the American form from 

 the group of Schwagerina with a fusiform shell, such as 5. fusulinoides Schellwien 

 and S. fusijormis Krotow. The former, according to Schellwien, has "die grosse 

 Centralkammer, die Hin- und Herbiegung der Septen, die in der median Ebene 

 nie den Boden erreichen, Merkmale welche den Fusulinen zukommen," while 

 Triticites secalicus possesses, besides these characters, the thick septa of a Fusulina 

 s. s. Therefore, until more important differences from Fusulina s. s. and Schwa- 

 gerina are found, it seems to me unnecessary to keep Triticites as a distinct genus, 

 or even as a new subgenus. ^ 



Dr. Schellwien in his last monograph on the Fusulinas under the 

 observations relating to the species F. montipara (Ehrbg.) Moller 

 makes the following statement:
