Bos primigenius in the north of Scotland ; and Dr J. A. 
Smith mentioned that its remains had been found in Selkirk- 
shire and Roxburghshire, and referred to notes he had col- 
lected some time ago, in regard to the skulls preserved in the 
Museum of the Society of Antiquaries of Scotland, which he 
might lay before the Society at another meeting. 
II. On Goodsirea mirabilis, an undescrihed Gymnopthalmatous Medusa, 
By T. Strethill Wright, M.D., &c. 
Three specimens of this medusa were ta,ken in the Firth, near 
Queensferry, in September last, one of which the author placed 
on the table this evening. In general form it resembled the 
Plancia gracilis of Forbes ; but it differed from that animal 
in the shape of its smaller tentacles, the absence of eye-specks, 
and the presence of auditory organs. The disc was hemisphe- 
rical, depressed, in some specimens elevated in the centre, and 
about an inch in diameter. Its margin was furnished with 
two large colourless tentacles, which were capable of being 
produced to the length of about two and a-half inches. For 
about one-third of their length they were hollow, and per- 
meated by the circulating fluid of the lateral canals. The 
proximal portion of the large tentacles was covered with long, 
narrow, curved thread- cells, arranged in clusters or cones, 
like the piled muskets of a regiment of soldiers. These, to- 
wards the distal ends, became mixed with large, scattered 
thread-cells, of an ovate, or rather almond shape, in the inte- 
rior of which a long, loosely-coiled, smooth thread was very 
distinctly visible. The tips of the large tentacles were almost 
entirely furnished with the last kind of thread-cell. In addi- 
tion to the large tentacles, the margin of the disc bore ninety- 
six small tubercles, each of which was connected with two ex- 
ceedingly minute and delicate tentacles, of very complicated 
structure. The tubercles themselves were covered with the 
long, narrow thread-cells above-mentioned. The proximal 
ends of the smaller tentacles, for about one-third their length, 
were destitute of thread-cells, but were furnished with very 
thick, short palpocils. This portion of the tentacle terminated 
in a knob or swelling, which was covered with exceedingly 
minute thread-cells ; then succeeded a portion formed of
