M.janus Hudson. — In the following inland lakes of Michigan: McLaren Lake, Oceana County ; 
Crooked Lake, Newaygo County ; Horsehead Lake, Mecosta County ; Chippewa Lake, Mecosta County 
(Jennings, ’94). Mr. John Hood has recently called my attention to the fact that the Melicerta floccu- 
losa, described (without a figure) by Kellicott (’96), from Sandusky Bay, resembles in almost, if not 
quite, every respect M.janus, except in the possession of a tube without pellets. Now, Mr. Hood finds 
M.janus in Scotland inhabiting tubes without pellets, so that there is a strong probability that he is 
right in believing Kellicott’s M.flocculosa to be really M. janus. Kellicott’s description of M.flocculosa 
is so meager that it is difficult to find facts upon which to base a positive opinion; the only point in 
the description of M.flocculosa which might be held not to coincide with thatof M.janus is that Kelli- 
cott says the chin is spatulate, whereas in Hudson’s description the chin is said to be two-pointed. It 
will probably be best to consider M.flocculosa, at least provisionally, as a synonym of M.janus. 
M. tubicolaria Ebr. — Exhibited in New York (Helm, ’89). Sandusky Bay, Lake Erie (Kellicott, ’97). 
M. flocculosa Kellicott. — See M.janus.

(J. C. S., ’83). Shiawassee River at Corunna, Mich. (Kellicott, ’88.) Sandusky Bay, Lake Erie, and 
Niagara River (Kellicott, ’96). Exhibited in New York (Helm, ’97). Waters connected with Illinois 
River at Havana, 111. (Hempel, ’98). 
L. shiaivasseensis Kellicott. — Shiawassee River at Corunna, Mich. (Kellicott, ’88). Sandusky Bay, 
Lake Erie (Kellicott, ’96).

L. socialis Leidy = L. ceratophylli Schrank. 
Cephalo siphon limnias Ehrenberg. — Along shore of Niagara River (Mills, ’81). Buffalo, N. Y., and 
Shiawassee River Michigan (Kellicott, ’87). Corunna, Mich. (Kellicott, ’88). Olentangy Creek at 
Columbus, Ohio (Kellicott, ’89). Lake St. Clair (Jennings, ’94). Sandusky Bay, Lake Erie (Kellicott, 
’96j. Waters connected with Illinois River at Havana, 111. (Hempel, ’98). 
C. candidus Hudson. — Olentangy Creek, Columbus, Ohio (Kellicott, ’89). 
C. furcillatus Kellicott = CEcistes melicerta Ehrenberg. 
GZcistes melicerta Ehrenberg. — Olentaugy Creek at Columbus, Obio (Kellicott, ’89, under the name 
Ceplmlosiphon furcillatus). Swamp on the shore of Lake St. Clair (Jennings, ’94). This species is 
represented by Stokes (’81, fig. 2) without a name, probably from New Jersey. The two dorsal hooks 
are developed in many specimens into two great branched antler-like structures, which are shown in 
plate 14, fig. 3. There seems to be no justification for the change of the specific name from melicerta, 
as given by Ehrenberg, to ptygura, as given by Hudson and Gosse.
