epidermic glands ol L. loxalina, and may be compared 
with the figures of sections of the similar organs of L. 
saltans (figs, 15 and 16), which resemble far more closely 
the “flask organs” of Nickerson on L. Davenporti. It is 
pretty clear that they are all essentially similar morpho- 
logically, whatever their function may be. From the distinct 
character and constancy in position of the lowest pair we 
may assume that these particular ones have a special function. 
They are more deeply set than the others. 
The foot is circular and devoid of any special gland such 
as L. tethy ^ and L. leptocli ni possess. It has, however, a 
peripheral row of unicellular structures, which may be mucous 
or some form of adhesive gland which project beyond the 
general contour as the toes of a frog- project beyond the web 
(fig. 13). But quite possibly they may be of firmer con- 
sistency and serve as stiffening rods. 
The lophophore of this species as well as L. saltans 
is not circular in outline, but slightly indented along the oral 
region, at first sight suggesting the condition in the Phylacto- 
laemata, but in them the inflection is of the anal region. The 
tentacles in every case I have counted number sixteen, and 
are not all of the same size. Four along the anterior or 
indented part are longer than the rest, and a gap occurs 
between the two inner ones of the four. The same characters 
are seen in L . sa 1 tan s, and apparently also in L. tethym 
according to Salensky, thoug-h only two tentacles are shown 
by his figures to be longer than the others. 
Alimentary Canal. — The whole body is very much com- 
pressed in the oro-anal axis, but does not show auy features 
very strikingly different from those of other species of 
Loxosoma. The rectum is carried far along the hood of the 
lophophore, so that the anus lies near the rim of the lophophore 
as in L. crass'icauda, butunlike L. Davenporti, where the 
rectum ends about the centre of the lophophoi-e hood. The 
rectum is wider than the intestine and its walls contain cells 
with brown inclusions, which are probably excretory products 
(vide L. saltans). The whole body being longer in L. loxa-
