Jan., 1903.] Ohio Reptiles and Batrachians. 361 



A rgzs ior April, 1891. The paper is based on personal work in 

 several parts of the State and on the material in the museums of 

 the State University and the State Experimental Station. Several 

 species of which Mr. Wilcox was uncertain as to identification 

 were submitted to the late E. D. Cope, and hence bear the stamp 

 of high authority. This Exerimental Station collection is at 

 present in the State University Museum. 



Those in charge of several of the museums of the State have 

 been so kind as to furnish me lists of the specimens in these 

 museums bearing Ohio labels. I have gone over the two mono- 

 graphs of E. D. Cope, "The Crocodiles, Lizards and Snakes of 

 North America," published in the Annual Report of the United 

 States National Museum for 1898, and " The Batrachia of North 

 America," being Bulletin 34 of the same institution. Several 

 records are given there of the occurrence of these forms that are 

 additions to the other lists. 



From all sources I have found thirt^'-four batrachians and fifty- 

 one reptiles recorded for the State. Several more could be in- 

 cluded from less certain sources, but this number includes only 

 tho.se that have been published or are in the several museums of 

 the State. There are many doubtful species which are said to 

 occur in certain localities, and only collections made in such 

 regions can settle the questions at issue. The true moccasin of 

 the South has been reported from the southern part of Ohio. 

 Such is possible, but it is very easy to confuse this poisonous 

 reptile with Natrix faciata sipedon.

F.DO. Cr.AASSEN. 



This moss, which is suppo.sed to be ver}- rare in the United 

 States, was found by me in six localities in Cuyahoga county, 

 always on the north side of ditches, river-banks or steep moist 

 embankments adjoining country roads or railroads. Although ot 

 a very .small size (barel>' that of a pin), its presence on the clayey 

 soil may be easily ascertained, in the fall of the year, by its yel- 

 lowish-green protonema. Many thousands of inciividuals were 

 ob.served in several localities, the protonema covering many square 

 feet, often with no less than 300 specimens to the square inch. 

 In October the moss-plants have several small .scales and a short 

 wire-like setae, with here and there the beginning of the capsule. 

 In April the plants are about an inch long and the capsules are 

 nearly full grown, while there may be no ripe capsules before 

 June.
