us in Hep. Amer. 38 and by Macoun, Can. Hep. 19* Fortu- 
nately Lindberg, a year earlier than Spruce, had given the species 
a name that will effectually blot out the confusion arising from 
the use of the homonym, C. mud/tiffora. 
3. CEPHALOZIA SULLIVANTIAE ( Aust.) 
Jungermannia Sullivantiae Aust. Bull. Torr. Bot. Club, 3: 12. 
1872. (Not /. Suélivantit Aust. Proc. Acad. Phila. for 1869: 221. 
1869.) 
Gametophyte a short, close-creeping, sparingly branched stem ; 
leaves whitish, usually spaced, about 0.3-0.35 mm. long, two-thirds 
as wide, strongly narrowed just above the base, somewhat ovate, 
erect, spreading or nearly horizontal, bifid to one-half or two-thirds 
their length, with obtuse sinus and acute usually divaricate divi- 
sions; leaf cells 25-30 y in diameter; dioicous; perianth at the 
end of a very short branch, obovate-oblong, 1.2-1.5 mm. long, the 
mouth deeply to.cleft; involucral leaves mostly bifid with a large 
tooth on the outer margin near the middle or towards the base. 
Sporophyte a short-stalked mostly short oval capsule; mature 
Spores not seen. 
Apparently an uncommon species, seen only as yet from Ohio, 
Whence it was distributed by Sullivant: Musc. Alleg. 241 (as 
JSungermannia bicuspidata, var. 2); Austin also reported it from 
Illinois, but I have seen no specimens. The name is unfortunately 
too near C. Sullivantii and may need change to prevent confu- 
sion. 
4. CEPHALOZIA CATENULATA (Hiiben.) Spruce, On Cephalozia, 33. 
1882.

; *In my set of Macoun’s Canadian Hepaticae this species occurs under the fol- 
lowing numbers: 
No. 39 as Cephalozia Lammersiana., 
No. 18 as Cephalozia catenulata. 
No. 20 ( mostly) as Cephalosia pleniceps. | 
The Species thus appears in one set of exsiccatae under four distinct names! The 
Smaller species of Llepaticae, like Cephalosia and Marsupella, are likely to grow in 
termixed, so that the greatest care is necessary in selecting them for issues of exsic- 
Catae wh ch are to be used as works of reference. Spruce has called attention to the a
