106 PLANARIA. 
I have had numerous specimens, but without being able to identify 
them with either the Planaria tremellaris, or Planaria atomata. How- 
ever, this is not on account of the scalloped margin with which these species 
are represented, for I doubt if any of the marine species shew any 
marginal irregularity, unless from constraint, so that such distinctions 
are delusive.

e.—PLANARIA HAUSTRUM— Lhe Scoop Planaria.—Plate XIV. Figs. 36,37, 38. 
Length above a line ; breadth about a third of the length ; snout 
straight, body flat, flexible, the sides often folding so as to resemble a 
scoop. The body tapers from about the middle to the posterior extremity, 
which is pointed, whereon the animal rises erect ; also adhering by it. 
Colour brown, speckled. Motion swift, beg the most active of any of 
the Planariz. 
No specks or eyes perceptible. Marine. 
This species dwells in the pools among the rocks at Eyemouth, at 
somewhat within half tide. Specimens may be obtained by washing a 
quantity of marine plants, especially the Fuci, in a white basin, or a large 
white saucer. 
Some have survived nine months. 
The Planaria convoluta of Miiller, has considerable analogy to this 
species.
