Jordan and Ever mann. — Fishes of North America. 2597 



tbo fact that of those observed ou the British and Scandinavian coasts 4 

 were observed iu the month of January, 5 in February, 8 in March, 2 in 

 April, 1 in May, 1 in June, 1 in July, 2 iu August, 1 in Sex)tember, and 1 in 

 October. He also calls attention to the fact that by far the greater pro- 

 portion of their capture, in the Northern Hemisphere at least, is in the 

 stormy season. This agrees with what we know of the capture of Tra- 

 bhijptirus, which likewise seems to be brought to the surface only by great 

 commotions of the oceau. The popular name of lUtjalecus is oartish, in allu- 

 sion to the blade-like expansion of the extremities of the 2 ventral lins. 

 Bvfialecus is also called in the books the ''king of the herrings." Strano'ely 

 enough, no represeutative of this genus has been found on the coast of 

 North America. Giinther is of the opinion that the distribution of this 

 fish iu the depths of the sea is the same as that of Trachypterus. The simi- 

 larity in their geographical distribution is quite remarkable. (Goode &
