Centropages hradyi Wheeler was taken in Acadia stations adjoining the Gulf 

 Stream in the vertical hauls, viz., at 41, 42 ; in deep surface haul and vertical haul at 

 75. C. typicus was taken by Dr. Huntsman in the Bay of Fundy at Prince stations 

 2, 3 and 4. 



14. Temora stylifera. — WTiereas Temora longicornis is as widely distributed as is 

 Centropages hamatus, Temora stylifera occurred in some numbers only at Acadia 

 station 44. Most of the animals were females in the adolescent stage which differs so 

 remarkably from the adult form that I was for some time in doubt as to their identifi- 

 cation. The lateral ang-les of the head are drawn out into two free processes like those 

 of trilobites (fig. 26). Unfortunately I have not had access to the original description 

 of the species by Claus, but the processes are not mentioned in the works of reference 

 which I have consulted as they do not occur in the full-grown stage. Otherwise the 

 structure of the appendages is typical. An adult male, 1-75 mm. had no prolongations 

 of the lorica.
