Here and there the English used is not beyond question, being 
sometimes inelegant, sometimes confused. The term “ urinogenital ” 
has been cast into limbo by Huxley (Zife and Letters, Vol. II, p. 63), 
but language is a dangerous thing to discuss. So much depends 
upon the point of view, and. our authors have occupied. a peculiar 
position for seeing things, as we learn from the legend of Fig; 200, 
which represents the right half of a lamprey *seen from the inside 
of a female specimen." The mechanical part of the work is well 
done, and the illustrations, mostly zinc etchings, are clear, and: as a 
rule bring out well the points made in the text. K. 
Notes. — Wallengren (/enaische Zeitschrift für Naturwissenschaften, 
Bd. XXXVI, pp. 165-180, Taf. VII-VIII) gives a brief but interesting 
account of the innervation of the proboscis of some of the polychate 
worms. The sense cells always occur in the papillz of the proboscis, 
never on the surface between papilla. In Nephthys and Phyllodoce 
they are radially arranged within a papilla, but in Glycera and Goniada 
they are grouped into multicellular organs, and single sense cells do 
not occur. In all cases the distal ends of the sense cells pierce the 
superficial cuticula, and in Glycera at least they end externally in a 
brushlike expansion. Proximally the fiber from each cell body either 
passes undivided to the central organs, as in Nephthys, or gives off 
branches at the base of the papilla, forminga subcutaneous nerve 
plexus as in Glycera. No observations were made on the functions 
of these organs. 
The ganglion cells of the electric lobes in the Torpedo are said 
by Hatai (Journal Cincinnati Society of Natural History, Vol. XX, 
pp. 1-12, Pl. I) to show an apparent fibrillar structure suchas that 
described long ago by Max Schultze. Bundles of fibrils seem to enter 
the cell from the dendrites as well as from the neurite. This appear- 
ance, however, is due to the form of the protoplasmic reticulum, 
the meshes of which are much drawn out in the regions of the cell 
processes, and does not indicate the presence of true nerve fibrilla. 
While the bundles of fibrille as described by Schultze are thus. 
explained away, those discovered by Bethe and Apàthy belong to 
another category and probably are dun pin Gradations from
