usually is found smaller. The back (mantle) is whitish to pale 
tan, or grayish, “with clouds and spots of brownish and blackish 
so arranged as to form three ill defined longitudinal bands.” On 
the variations of color, Binney has noted seven varieties, not 
named, and it has been suggested, recently, that at least some of 
them are probably distinct species. The question should be 
settled by examining the jaw, radula, genital organs, etc. 
2. Ph. dorsalis Binney (Pallifera dorsalis, in Morse) is the 
smallest known now, the animal attaining a length of only about 
eighteen millimeters. It£ color on the dorsal side is gray with a 
shade of blue, and a more or less interrupted dark median line. 
It is probably distributed all over Ohio, but has been overlooked 
or taken for the young of some other slug. 
3. Ph. sp. I collected two specimens in the woods east of 
Chippewa Lake, the only ones known from Ohio. They were 30 
millimeters long when extended, very slender, light tan colored 
over the back, with very slight darker mottlings, the sole anteri- 
orlv with a tinge of blood red. The jaw and radula were differ¬ 
ent from those of other species. Being possibly identical with 
Ph. pennsylvanicus Pilsbry, they were left unnamed for the 
present. 
4. Ph. sp. Of the same size as caroliniensis or rather some¬ 
what larger. The body is less opaque, and the surface gyrations 
are somewhat different. There is a series of irregular black 
spots along each side, and small irregular white spots are scat¬ 
tered over the whole mantle surface. Jaw and radula are dif¬ 
ferent. Fifteen and twenty years ago, this was found rather 
frequently in the vicinity of New Philadelphia, in company with 
caroliniensis, and taken for one of the color varieties of the latter. 
Both are more scarce now. Specimens carefully examined last 
summer showed that they are of a distinct species, which will 
doubtless be found in other parts of the state. It has been 
named Ph. hiseriatus. provisionally. 
5. Ph. wetherhyi W. G. Binney has not been meorded from 
Ohio; but known from Kentucky (Laurel Covnty), and also 
from northern Michigan, it should be found within our limits. 
It is rather small, with dark blotches in irregular transverse 
bands or longitudinal series. The jaw and radula are different 
from those of other species. 
Other forms, and species may be found, and it is unnecessary 
to state that every specimen from any part of the state will be 
of interest.
