More recently a species of Loxosoma., the first actually 
described from the American side of the Atlantic, has been 
made the subject of an interesting paper by N. S. Nickerson, 
and named L. Davenporti, also from the tube of a 
Maldanid, namely Clymene producta. This species clearly 
has close affinities with the other Maldanid Loxosoma, L. 
ann el i dicola, as is shown for instance, by the possession of 
the wing-like expansion of the body and the arrangement of 
the foot muscles, but is quite distinct in many characters, such 
as the far longer stalk, peculiar epidermic “flask organs,” 
the more numerous tentacles, and the curious “ mammary 
organ” which the female of L. Davenporti possesses. 
The two new species which form the subject of this present 
paper are also from the tubes of Maldanid worms, and, as 
one might expect, bear certain i-esemblances to L. Daven- 
porti and L. aunelidicola, buttheyare clearly distinguish- 
able from these, as may be noted from a glance at prepared 
specimens. 
Loxosoma loxalina. 
Loxosoma loxalina was found in September, 1909, 
in ihe Sound of Mull, near the entrance to Loch Aline, in 
association with a iUaldanid, of which I have oidy an imper- 
fect specimen, and which I have been unable to identif}'. 
External Characters. — It is characterised by its long 
stalk as compared with the other known Maldanid associates, 
the stalk being longer than the body and calyx together, 
though very much shorter than the stalk of L. Phascolo- 
somatum, aud the presence of curious projecting glands 
placed with some regularity on the sides of the body (tig. 1), 
which, though more numerous and smaller, are no doubt 
cotnparable to the “ flask organs ” described by Nickerson on 
L. Davenporti, although they occupy a different position. 
Ectodermic glands, unicellular or multicellular, occur on 
other species, e.g. L. Tethyae, L. crassicauda, and L. 
phascolosomatum, though in these cases they are sunk
