Notes on the above List. 



Hake (Merluccius vidgaris, L.). The egg which has been provisionally 

 regarded as that of the hake has a diameter of 1*31-1 '36mm., with an oil 

 globule measuring *25-'35mm. Holt* gives the size of this egg as 1*35 X 

 l-08mm. • oil globule, -3mm. According to Raffaele,f the egg of the 

 species measures -94-1 '03mm. (O.G. | -27mm.). Mr. H. M. Kyle has 

 informed me that ripe eggs taken from a hake at Banyuls measured less 

 than 1mm. in diameter, while other eggs measuring l*07mm. (O.G. 

 •23-* 2 7mm.), captured in the Mediterranean, produced larvae agreeing 

 exactly with Raffaele's description of the hake embryo. The disparity 

 between the sizes given by Holt and Raffaele is too great to be accounted 

 for merely by the variation found among the eggs of every species. 



Mackerel (Scomber scombrus, L.). The size of the egg of this fish is 

 given by Cunningham § as l'22mm. in diam., O.G. , 32- , 33mm. In 

 the Loch Fyne collections, ova measuring 1*2-1 -25mm. diam., O.G. 

 •3-3 7mm., were obtained. The eggs of the mackerel have not, so far, 

 been described from Scotch waters, but numbers of ripe mackerel are 

 caught each year in Loch Fyne, and it is extremely probable that the 

 diagnosis of the latter egg as mackerel is correct. 



Pollack (Gadus pollachius, L.). Holt || gives 1*1 3mm. as the size of 

 this egg. This agrees closely with the dimensions given by M'lntosh* 1 !]', 

 viz., l*14mm. A number of eggs measuring l'llmm. were captured in 

 Loch Fyne, and as this size is a little smaller than the average size of the 

 saithe, they were regarded as Pollack. In the case of preserved eggs, a
