FAMILY LIMACID2 — LIMAX. 21 
distinct concentrical furrows, centering on its posterior portion. Breathing-hole on the right 
side,* above the lower edge, and in the posterior third portion of the mantle. Vent adja- 
cent, and slightly above and anterior to it. Upper tentacles terminating in a small bulb ; lower 
tentacles much shorter. 
Color. Various, but most usually dark reddish or chocolate-brown, varied with numerous 
minute blackish brown dots and lines ; the mantle somewhat darker. Occasionally the gene- 
ral color is greyish. ‘Tentacles darker than the general color. Foot beneath flesh-colored. 
Breathing-hole greyish or white on its margin. 
Length 1°5 — 1-7. 
Found on the underside of leaves and decayed branches lying on the ground; also under 
stones and boards. Their chief food appears to consist of succulent leaves. Rarely seen 
during the day. I make no reference to names of species published by myself some years 
since, as the descriptions have been anticipated. This species varies much in its color and 
markings, and is invariably smaller than the following.

L. variegatus. Lam. An. sans. vert. Vol. 3, p. 266, No. 15. 
L. flavus. Binney, Limacide, Bost. Jour. Vol. 4. 
Description. Surface with iong narrow prominent tubercles. Mantle short, broad, oval, 
concentrically striated. Breathing-hole large, near the posterior part of the mantle, and cleft 
tothe edge. Neck smooth. Body terminating acutely behind, with a short ridge. 
Color, varying from deep reddish brown to light ferruginous, mottled with oblong-oval 
greyish spots. Mantle with rounded spots. Head, neck and upper tentacles much lighter 
than the general hue: the latter lineated with dusky at their bases. Foot greyish on the 
margin. 
Length, 2:0 - 2°8. 
This species was obtained from gardens in the city of New-York. It has also been noticed 
in Philadelphia. I have adopted the names proposed by Mr. Binney, but with much scepti- 
cism in relation to the introduction of foreign species of this family. I have, however, had 
no opportunity of studying the foreign species to which these have been referred. 
+ Through inattention, both the figures of Limaccs in Plate I. are represented with the breathing-holes on the left side.
