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 undescribed Gymnopthalmatous Medusa, 

 By T. Strethill Wright, M.D., &c. 



Three specimens of this medusa were taken 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
