Sullivant’s Muscology. ae 
RICHEN, &c., here removed to Leskea. No. 70, L. flaccida, is a 
re-discovery of a well marked species sent to Bripet by Torrey. 
No. 71, L. fragilis, Hoox. and Wits., which has a range from 
Montreal to New Orleans, is still distributed without fruit, which 
is a great desideratum. To No. 72, L. intricatula, Hepw., a 
goodly number of nominal species are referred. 
No. 79, Neckera breviseta of Hooxer and Witson, is deemed 
by Mr. Suxtivanr to be much more nearly allied to N. Cladorrhi- 
zans, than to the species with which these authors compare it. 
To No. 80, Clasmatodon pusillus, Hoox. and W1ts., Mr. Sut- 
Livan refers with some doubt the Leskea parvula of Hamre, and 
also Pterigynandrum marginatum of Micwavx ; if incorrectly, 
then this species of Micwavx still remains to be identified. 
No. 81, Cryphea filiformis, Brm., which is very common in 
the Southern States, is said to have spores four times larger than 
those of Daltonia heteromalila. 
No. 82, Anacamptodon splachnoides, Brio. Mr. SuLLIVANT 
has discovered that the genus Campylodontium of ScHw#GRICHEN 
was founded on specimens of this moss, which had lost their 
opercula and inner peristome! (Cf. Schwegr. Suppl. t. 52, cum 
t. 211.) 
No. 84, Pterigynandrum intricatum, Hepw., has as a syno- 
nym the Pylaisea heteromalla, Br. and Scuimp., which these 
authors detected in Drummonv’s Northern Mosses, (given by mis- 
take as Hypnum polyanthum,) but did not recognize. The P. 
julacerem, Hepw., here becomes No. 87, Leucodon julaceus. 
No. 88, Leptodon trichomitrion, Mour., is ‘distinguished from 
the new species that follows it by “statura majore, ramis pinna- 
tim ramosis, foliis humectatis erecto-patentibus ecostatis.” Sut- 
No. 92, Mnium affine, var. minor, is the M. Drummondii, Br. 
and Scump. 
No. 115, Pogonatum capillare, Brip., the Polytrichum capil- 
lare of Micwavx, is kept separate from P. urnigerum, and addi- 
tional characters are given for distinguishing it. ‘The specimens 
are from the White Mountains of New Hampshire. 
No. 135, Ptychomitrium pusillum, Br. and Scume., has some 
important synonyms for the first time referred to it, viz. Grrim- 
mia incurva, Muut., G. Muhlenbergi, Brww., G'. Hookeri, Drum- 
monp, and Notarisia Virginica, Hamre. ‘ ap
