Table for the determination of Pelagic Fish Eggs. 



By Heincke and Ehrenbaum. 



(Translated by J. Johnstone.) 



The folloAving Talkie is translated from that given by 

 Heincke and Ehrenbaum in the Kiel Kommission Report* 

 for 1900. It refers to the species found in the German 

 part of the North Sea, but will most probably appl}^ to 

 many of those inhabiting the Irish Sea as well. * 



In some cases the determination of the species is 

 uncertain. These are indicated in the table (i.e., " Trigla 

 sp.," where no attempt is made to distinguish the various 

 species) . 



The eggs of the species marked with an asterisk are 

 as yet imperfectly known. The Roman numerals indicate 

 the months during which the fishes spawn. The authors 

 claim that the table is useful chiefly as the means of a first 

 determination of the eggs, and more detailed information 

 as to special characters is given in the sj^stematic part of 

 their paper.

t Certain other species, of economic importance in our district, 

 are not included in this Table. These are: — Labrax lupus (Bass), 

 Merhiccius vulgaris (Hake), Molva vulgaris (Ling), Lepidorliomhiis 

 megastoma (Megrim), Mugil chelo (Lesser grey mullet), and Hippo- 

 glossus vulgaris (the Halibut). The main characters of the eggs of 

 some of these species are known but others still require investigation.
