tlio sizes of these varying from 0'36 to 0*18 mm. There were few inter- 
mediate between the large and small. The total number contaiaed in the 
ovaries would bo :— Large, 23,744; small, 118,720=142,464.

The greater part of the ovaries consisted of ripe eggs, from 0*72 to 0*77 
mm. in diameter. The small ova were all sizes, between 0*37 and 0"06 mm.

The ovaries of two specimens of this fish were examined, both caught 
off the east coast of Scotland, one on the 4th and the other on the 24th 
April. The roe is deeply coloured, orange-brown. The particulars are as

In the first specimen there were no large clear eggs, the whole 
mass of the ovaries being composed of eggs of a nearly uniform size, 
thus dilfering from the Gadidae, in which very various sizes are found. 
Mr Mair, who obtained the second specimen, thinks that it had voided 
some of its ova, a supposition supported by the relative weights of the 
ovaries in the two specimens. Large clear ova were found in this speci- 
men, having a diameter of from 1*4 to 1*32 mm., but very few, not above 
forty or fifty, in the 3612 counted. The opaque ova ranged from 1 to 
0-7 mm.

The Greate-r Sand-eel (Ammodytes lanceolatus). 
The reproduction of the sand-eel has hitherto been involved in much 
obscurity. The spawning and ovum of this fish have now been determined 
by Professor M'Intosh {vide p. 331). Three specimens, caught at Elie,
