in the deep caverns, however, in the sides of the island, where 

 the maidre is found in greatest abundance ; and accordingly, 

 we find that all those animals pursuing them are found there 

 in greater abundance also. 



The fishermen, during the earlier periods of the fishery take 

 advantage of this, and, shooting their nets across the mouths 

 of the caves, alarm the herrings in them, either by throw- 

 ing large stones from their boats or from the tops of the rocks 

 — and in this way sometimes succeed in taking great shots. 



These, however, are not the only animals which prey on 

 the immense bodies of maidre. 



Great numbers of cetacea often frequent the neighbourhood 

 of the island at this time ; droves of dolphins and porpoises, 

 swimming about with great activity ; and occasionally an im- 

 mense rorqual may be seen raising his enormous back, at in- 

 tervals, from the water, and is to be observed coursing round 

 and round the island. 



I have examined great numbers of these cetaceous animals 

 (dolphins and porpoises) within the last few years, and never 

 have seen anything resembling the remains of herrings, or 

 fish of any other kind, in the stomach, although the former 

 fish was very abundant at the same time in the Firth. I 

 make no doubt, therefore, that these cetacea only accompany 

 the herring in pursuit of their common food, viz., Entomostraca 

 and Acalephae. 



I have already stated that it was entromostracous animals 

 which formed the great mass of the maidre. Among these I 

 obtained a great number of nondescript species, one of which 

 I shall now describe. 



On one of my occasional visits to the Isle of May, I observed 

 that at a considerable distance from the island the sea had a 

 slightly red colour, that this became deeper and deeper as we 

 neared the island ; and also that the surface of the water pre- 

 sented a very curious appearance, as if a quantity of fine sand 

 were constantly falling on it. I thought at first that this last 

 circumstance proceeded from rain, but presently 1 found that 

 both phenomena were caused by a great number of small red 

 Entomostracea, which I had never before observed in such 

 abundance. Ou further observation, I found that it belonged 

 to the genus Cetochilus of M. Rousel de Vauzeme, who ha»
