of development in as many different locations, starting from the same 
species and leading to such practical identity of result.” 
Ably arguing the case from the data on hand, Garman came to the 
conclusion “that these blind fishes originated in a particular locality, and 
have been and are being distributed among the caves throughout the 
valley” (of the Mississippi). 
Two of the specimens from Missouri served Kohl (“Rudimentire 
Wirbelthieraugen,” 1892) for his account of the eyes of North American 
blind fishes. At my request Mr. Garman sent me two of the Missouri 
specimens. He urged me at the same time to make a more extensive 
comparison between them and the Mammoth cave specimens. A compari- 
son of the eyes of specimens from the two localities not only proved that 
they represented distinct species, but that they are of separate origin. 
An announcement of the species without further description was published 
(Proce. Ind. Acad. Sci. for 1897, p. 231, 1898). The species was “named 
ros@ for the rediscoverer of the California Typhlogobius, a pioneer in the 
study of biology among women, Mrs. Rosa Smith Eigenmann.” In the 
spring of 1897 I visited various caves in Missouri to secure additional 
material of what was recognized as in many ways the most interesting 
member of the North American fauna. No specimens were secured, but 
a liberal number of bottles of alcohol and formalin were scattered over 
the country. During this fall, through a grant from the Elizabeth Thomp-
