course this does not preclude a trip of which no written record 
is made. Our party (1912) of thirteen was in the heart of the 
swamp for six weeks with no fever contracted thereafter and our 
record accords with the experiences of the Thompson brothers in 
Civil War times, with those of the surveying parties of 1879, and 
with those of the Harper brothers (1902-17). 
In 1894 Dr. Einar Loennberg compares the source of the 
marine and fluviatile elements in the ichthyfauna of Forida as 
follows: “From this it is thus evident that in the marine fishfauna 
of Florida the tropical components really are ruling. But this is 
not the case in regard to the ‘ichthys’ of the freshwater. If we 
completely omit all marine fishes, which not few in number, 
ascend streams and rivers and sometimes penetrate deep into 
the country, we can divide the real fresh-water fishes of Florida 
into two classes. 1) Fishes with wide distribution and which 
can be found far north from Florida. To this belong Lepidosteus, 
Amia, most of the catfishes, Erimyzon, Notemigonus, Dorosoma, 
the eel, Esox reticulatus, Eabidesthes, Pomoxys, Chaenobryttus, 
Enneacanthus, Lepomis pallidus and Micropterus. Some other 
ones do not extend so far north, but go at least to South Caro- 
lina,* as Zygonectes chrysotus, Gambusia, Girardinus and Lepomis 
holbrooki. All in all this class will embrace about a quarter of 
a hundred. The second class should include the typical Florida- 
fishes, but they are only half as many. To them belong Amiurus 
erebennus, Jordanella, Fundulus seminolis and F. ocellaris, Zygon- 
ectes henshalli and craticula, Lucania goodei, Elassoma ever- 
gladei, Lepomis punctatus and mystalis. A few are found in 
Florida and also in Georgia as Notropis roseus, Etheostoma qui- 
escens. Molliensia latipinna extends westward to Mexico and 
Lepidosteus tristaechus southward to Cuba and Central America. 
As this second class however is not but about half as large as the 
first, the fresh water fauna of Florida with respect to the fishes 
can be said to have originated from the North and is thus not 
tropical. This is the more the case as most of even these fresh- 
water fishes that are typical for Florida have relatives belonging 
to the same genera in other parts of North America.” 
At present there are few freshwater fishes which might be termed 
strictly Floridan, to wit: — Jordanella doridae, Lucania goodei, 
Fundulus seminolis, Fundulus henshalli and Ameiurus erebennus 
(the latter probably synonomous with Ameiurus natalis and not so 
important in this discussion). 
In this connection it is interesting to note two casual collections
