A REVIEW OF THE MYSIDACEA 



27 



fathoms, and the other from 858 to 2,033 fathoms in 1883. I think 

 the former must refer to those specimens of G. gigas from Albatross 

 stations 2083 and 2099. Fowlers paper (1912) is merely a compila- 

 tion of previous literature and I think his records of G. gigas must be 

 based on Ortmann's paper. In error he gave Thomson as the authority 

 for both G. gigas and G. zoea, and curiously enough he refers both 

 species to the Stomatopoda. 



On the west coast of America Ortmann recorded this species from 

 four localities off the coast of Alaska and most of the specimens from 

 the Pacific in the list of records came from localities in the North 

 Pacific more or less in the same area as Ortmanirs. This species 

 penetrates into northern latitudes in the Pacific farther than any 

 other species of the genus, and Stephensen (1933) has recorded it 

 from near the coast of Greenland, in the North Atlantic Ocean. 



Remarks. — In table 4 I have given measurements showing the total 

 length of the specimens, measured from the eye to the end of the 

 telson, the percentage of that length of the rostrum and the postero- 

 lateral spines, and also the number of teeth on the antennal scale 

 excluding the terminal spine.
