Seite 32 - ... they cover the surface generally, and form dense groups round the spines. Each consists of a soft stem, bearing on its summit, or (when branched) at the point of each branch, a sort of forceps of calcareous matter not unlike a crab's claw, except that the two blades are equal and similar. When the point of a fine needle is introduced between the blades, which are for the most part open in a fresh and vigorous specimen, they instantly close and grasp it with considerable force.

The organs of the other known electrical fishes have not yet come under the notice of any anatomist. In all these instances the electrical organs are supplied with nerves of very great size, larger...

Seite 35 - This vessel lies immediately within the calcareous ring already described as connecting the rays at the commencement; from it a straight canal proceeds along the floor of each ray in the median line, and in its progress gives off lateral branches, which open into the vesicles of the feet. There are moreover connected with the circular vessel — First, a certain number of bodies (ten in five-rayed species) which Tiedemann compares to glands ; they are very small, brown, sacculated organs, each opening...
Seite 360 - Flexor brevis pollicis, into the outer side of the base of the first phalanx of the great toe.
