without the use of its eyes longer than any other known vertebrate.” 
« More than this, 7: rose is probably the oldest resident in the region 
it inhabits.” 
The remaining genus of blind-fish, Amblyopsis, has ventral fins, and 
must therefore have had a distinct ancestry, as in the three other 
genera ventral fins are absent. All this points to an earlier time 
when the Amblyopsidz were represented in the lowlands of the South 
by at least three distinct-eyed genera, but one of which, Chologaster, 
is now extant. Eigenmann regards Troglichthys as “in many ways 
the most interesting member of the North American fauna.”

Trout of the Olympic Mountains. — Some three years ago Rear- 
Admiral L. A. Beardslee brought from Crescent Lake, in the Olympic 
Mountains, two new forms or species, or subspecies, of trout, called 
by Dr. Jordan Salmo crescentis and Salmo beardsleet. 
These forms are products of isolation and land-locking, the prob- 
able ancestor of both being the Steelhead trout, Sa/mo gairdneri. 
Lately Dr. Daniel G. Elliot, of the Field Columbian Museum, has 
made an extensive survey of these and other lakes in the same moun- 
tains. Other land-locked forms, also differentiated by isolation, are 
found, and these have been described in detail by Dr. Seth E. Meek 
in the publications of the Field Columbian Museum. 
Dr. Meek recognizes Sa/mo bathoiceter, the long-headed trout from 
Lake Crescent; Salmo clarki jordani, the spotted trout of Lake 
Southerland ; and Salmo clarki declivifrons, the salmon trout of Lake 
Southerland. 
The question of the ultimate rank as species, subspecies, etc., of 
our western trout is one of the most difficult in taxonomy. For- 
tunately, the question is one of nomenclature only, for the real 
origin and relation of the various forms admit in no case of 
serious question. 
In the same paper Dr. Meek describes new garter snakes from the 
same region as Thamnophis leptocephalus olympia and Thamnophis 
rubrostriatus. DS 
Fishes of the Revillagigedos. —In the Report of the U. S. Fish 
Commission for 1898, Dr. Jordan and Mr. R. C. McGregor give a 
list of the fishes taken by Mr. McGregor on the cruise of the 
Wahlberg about the Revillagigedos, off the west coast of Mexico. 
The interesting feature of the collection is the large number of
