24 Dy. A. Giinther on new Species of Snakes 
Hist.’ Dec. 1864, t. 9. f. 1-5, may be possibly different from 
the typical 7h. Laureri, Flot. Should this prove to be the 
case, the name he proposes, 7h. anglicum, must be adopted for 
the English plant, limiting 7. Laureri to the German speci- 
mens. Dr. Koérber, to whom I forwarded a specimen, com- 
pared it with his authentic specimen (but whether micro- 
scopically or merely externally, I know not), and thought 
them identical. Dr. Nylander has kindly afforded me an op- 
portunity of examining his Zh. intermediellum, which corre- 
sponds with the characters he has given of it. Recurring 
to my own specimens, I am disposed to think that the plant 
found by me parasitically on Baomyces rufus (see Ann. /. c.) 
will eventually prove to be another species (for which I would 
propose the name Thelocarpon epithallinum). In it I find the 
paraphyses to be stronger, unbranched, and shorter than in 
others, the asci more elongated, lineari-cylindrical, and the 
spores (which I could not disengage from the asci, and therefore 
may be optically deceived by the appearance of their close ap- 
proximation or packing) to be of an irregular spherical shape. 
There also appears a difference in the gonidia. But the plant 
was in too unsatisfactory a state to determine this decisively.

of the British Museum. By Auzert Gintusr, M.A., M.D., 
Ph.D. 
[Plates VI. & VII.] 
Tue followmg species of Ophidians have been added to the 
Collection of the British Museum since the publication of the 
last paper on the sare subject in this Journal (February 1865, 
p. 89). The total number of species in that collection amounts 
now to 827, and that of the typical specimens to 808. Our 
numerous specimens of Typhlopides have been examined by 
Prof. Peters, who has been for some years engaged upon a 
monograph of this family. 
In the following lists some of the species are marked with an 
asterisk (*): they will be described in this paper.
