Explanation of the Plate. 

 All the Fifjures were drawn idth the Camera lucida. 



Fig. 1. — Stem showing (obverse ?) face with cells of various sizes, some no 

 larger than pores. X 40. 



Fig. 2. — Portion of stem showing cell without pores; groups of pores without 

 cells; and an intercalated row of cells. X 40. 



Fig. 3. — Well preserved fragment showing tubercular ridges surrounding 

 cells, pores, and (aborted ?) cells. At one point in the left hand row a space is 

 enclosed between two transverse tubercular ridges, but no cell nor pore is 

 visible in it. X 120. 



Fig. 4. — Transverse division of cell aperture, the upper chamber seeming to 

 replace pores. 



Fig. 5 shows cells of various sizes, and pores, surrounded by tubercular 

 ridges. In the middle row one cell is transversely divided, while immediately 

 below it two cells are associated with one group of pores. 



Fig. 6 shov/s numerous tubercular ridges, some without intervening cells. 



Fig. 7. — Single cell, from worn specimen, with two pairs of pores. 



Fig. 8. — Bifurcating stem, showing confluence of intercalated rows, irregular 

 arrangement of pores, and abortion (?) of cells at angle of bifurcation. X 60. 



Fig. 9. — Branch '028 in diameter, showing, in left hand row, transverse 

 division of a cell, while in each of the two upper cells of the same row, the 

 lowest of the three pores is included by a A shaped ridge within the same area 

 as the cell aperture. 



Figs. 10 and 11. — Fragments showing irregularity in number, size, and 

 position of pores.

SPECIMENS EXHIBITED. 



Mr John Kirsop exhibited a horn and portion of the skull of 

 the extinct ox Bos longifrons, found at Pollokshaws Road in 

 sandy clay six feet below the surface. It had been forwarded 

 by Mr Gillespie, inspector to the Water Commissioners, and is 

 the second recorded specimen found in the West of Scotland. 

 Mr Kirsop also showed a collection of fishes from the river 

 Amazon, and from Rio Grande do Sul, South America. The 

 collection embraced examples of a flying fish of the gurnard 

 family Frionotus; a trunk fish, Ostracion; a skate or ray, Eaia; a 

 spinous globe fish, Diodon; a sucking fish, Echineis, 21 inches in 

 length; a speat fish, Loricaria; and two species of lobsters. 

 These had been forwarded by Mr James Albert Smith, and with
