Dental characters.—A glance at the accompanying drawing of 
the crowns of the molar teeth shows that Arvicola longicaudus has 
the back upper molar of Myonomes. e middle upper molar, 
however, lacks any trace of the postero-internal loop or spur sup- 
posed to be characteristic of this subgenus, and the lower teeth 
present several peculiarities not mentioned in any description or

ZOOLOGICAL News.—GENERAL.—The zoological papers in the 
Journal of the Elisha Mitchell Scientific Society for 1888 are: “A 
List of Fishes in the Museum of the University of North Caro- 
lina,” by V.S. Bryant; “List of the Butterflies collected at 
Chapel Hill, N. G.,” by A. Braswell; “ Aquatic Respiration 
in the Muskrat,” by W. L. Spoon; ‘ New Instances of Pro- 
tective Resemblance in Spiders,’ and “Notes on the Tube- 
inhabiting Spider, Lycosa fatifera,” by G. F. Atkinson. 
_ Protozoa.—The genus Gromia is usually regarded as an 
inhabitant of moist earth, but Dr. H. Blane describes a species 
which he considers as a member of the genus from the ooze 
at the bottom of Lake Geneva. His paper, which occurs in the 
l Zool. Suisse (Vol. IV.) is illustrated by a plate.
