24 Dr. A. Gunther on new Species of Snakes 



Hist/ Dec. 1864^ t. 9. f. 1-5, may be possibly clifFerent from 

 the typical Th. Laureri, Flot. Should this prove to be the 

 case, the name he proposes, Th. anglicum, must be adopted for 

 the English plant, limiting T. Laureri to the German speci- 

 mens. Dr. Korber, 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 Th. 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 Bceomyces 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. 



VI. — Fifth Account of new Species of Snakes in the Collection 

 of the British Museum. By Albert Gunther, M.A., M.D., 

 Ph.D. 



[Plates VI. & VII.] 



The following species of Ophidians have been added to the 

 Collection of the British Museum since the publication of the 

 last paper on the same subject in this Journal (February 1865, 

 p. 89) . The total number of species in that collection amounts 

 now to 837, and that of the typical specimens to 303. 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.
